We see, enjoy, and criticize the end result of writers' work, but there's so much more to these pieces than what the public consumes. After all, millions of books get published every year, joining the vast libraries that have been built up over time, but we regard few as classics, greats or masterpieces. So what makes the difference between just another piece of writing and a literary success ? Often, it's the writer.

Here's a collection of thoughts from world-famous writers on what literature means to them and why they pursued the written word as a means to express themselves.

Quotes About Writing and Literature

• Henry Miller : "Develop an interest in life as you see it; the people, things, literature, music-the world is so rich, simply throbbing with rich treasures, beautiful souls, and interesting people. Forget yourself."
• Ezra Pound : "Great literature is simply language charged with meaning to the utmost possible degree."
• Joseph Heller : "He knew everything about literature except how to enjoy it."
• John Steinbeck : "I hold that a writer who does not passionately believe in the perfectibility of man has no dedication nor any membership in literature."
• Alfred North Whitehead : "It is in literature that the concrete outlook of humanity receives its expression."
• Henry James : "It takes a great deal of history to produce a little literature."
• C. S. Lewis : "Literature adds to reality, it does not simply describe it. It enriches the necessary competencies that daily life requires and provides; and in this respect, it irrigates the deserts that our lives have already become."
• Oscar Wilde : "Literature always anticipates life. It does not copy it but molds it to its purpose. The nineteenth century, as we know it, is largely an invention of Balzac."
• G. K. Chesterton : "Literature is a luxury; fiction is a necessity."
• Virginia Woolf : "Literature is strewn with the wreckage of those who have minded beyond reason the opinion of others."
• Salman Rushdie : "Literature is where I go to explore the highest and lowest places in human society and in the human spirit, where I hope to find not absolute truth but the truth of the tale, of the imagination and of the heart."
• William Somerset Maugham : "The crown of literature is poetry."
• Johann Wolfgang von Goethe : "The decline of literature indicates the decline of a nation."
• Robert Louis Stevenson : "The difficulty of literature is not to write, but to write what you mean."

Like a Woman Who Gives Herself Without Preference

• Anatole France : "The duty of literature is to note what counts and to light up what is suited to the light. If it ceases to choose and to love, it becomes like a woman who gives herself without preference."
• E. M. Forster : "What is wonderful about great literature is that it transforms the man who reads it towards the condition of the man who wrote."
• Samuel Lover : "When once the itch of literature comes over a man, nothing can cure it but the scratching of a pen. But if you have not a pen, I suppose you must scratch any way you can."
• Cyril Connolly : "While thought exists, words are alive and literature becomes an escape, not from, but into living."

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Literature Reviews

What this handout is about.

This handout will explain what literature reviews are and offer insights into the form and construction of literature reviews in the humanities, social sciences, and sciences.

Introduction

OK. You’ve got to write a literature review. You dust off a novel and a book of poetry, settle down in your chair, and get ready to issue a “thumbs up” or “thumbs down” as you leaf through the pages. “Literature review” done. Right?

Wrong! The “literature” of a literature review refers to any collection of materials on a topic, not necessarily the great literary texts of the world. “Literature” could be anything from a set of government pamphlets on British colonial methods in Africa to scholarly articles on the treatment of a torn ACL. And a review does not necessarily mean that your reader wants you to give your personal opinion on whether or not you liked these sources.

What is a literature review, then?

A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period.

A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant.

But how is a literature review different from an academic research paper?

The main focus of an academic research paper is to develop a new argument, and a research paper is likely to contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.

Why do we write literature reviews?

Literature reviews provide you with a handy guide to a particular topic. If you have limited time to conduct research, literature reviews can give you an overview or act as a stepping stone. For professionals, they are useful reports that keep them up to date with what is current in the field. For scholars, the depth and breadth of the literature review emphasizes the credibility of the writer in his or her field. Literature reviews also provide a solid background for a research paper’s investigation. Comprehensive knowledge of the literature of the field is essential to most research papers.

Who writes these things, anyway?

Literature reviews are written occasionally in the humanities, but mostly in the sciences and social sciences; in experiment and lab reports, they constitute a section of the paper. Sometimes a literature review is written as a paper in itself.

Let’s get to it! What should I do before writing the literature review?

If your assignment is not very specific, seek clarification from your instructor:

• Roughly how many sources should you include?
• What types of sources (books, journal articles, websites)?
• Should you summarize, synthesize, or critique your sources by discussing a common theme or issue?
• Should you evaluate your sources?
• Should you provide subheadings and other background information, such as definitions and/or a history?

Find models

Look for other literature reviews in your area of interest or in the discipline and read them to get a sense of the types of themes you might want to look for in your own research or ways to organize your final review. You can simply put the word “review” in your search engine along with your other topic terms to find articles of this type on the Internet or in an electronic database. The bibliography or reference section of sources you’ve already read are also excellent entry points into your own research.

Narrow your topic

There are hundreds or even thousands of articles and books on most areas of study. The narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good survey of the material. Your instructor will probably not expect you to read everything that’s out there on the topic, but you’ll make your job easier if you first limit your scope.

Keep in mind that UNC Libraries have research guides and to databases relevant to many fields of study. You can reach out to the subject librarian for a consultation: https://library.unc.edu/support/consultations/ .

And don’t forget to tap into your professor’s (or other professors’) knowledge in the field. Ask your professor questions such as: “If you had to read only one book from the 90’s on topic X, what would it be?” Questions such as this help you to find and determine quickly the most seminal pieces in the field.

Consider whether your sources are current

Some disciplines require that you use information that is as current as possible. In the sciences, for instance, treatments for medical problems are constantly changing according to the latest studies. Information even two years old could be obsolete. However, if you are writing a review in the humanities, history, or social sciences, a survey of the history of the literature may be what is needed, because what is important is how perspectives have changed through the years or within a certain time period. Try sorting through some other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to consider what is currently of interest to scholars in this field and what is not.

Strategies for writing the literature review

Find a focus.

A literature review, like a term paper, is usually organized around ideas, not the sources themselves as an annotated bibliography would be organized. This means that you will not just simply list your sources and go into detail about each one of them, one at a time. No. As you read widely but selectively in your topic area, consider instead what themes or issues connect your sources together. Do they present one or different solutions? Is there an aspect of the field that is missing? How well do they present the material and do they portray it according to an appropriate theory? Do they reveal a trend in the field? A raging debate? Pick one of these themes to focus the organization of your review.

Convey it to your reader

A literature review may not have a traditional thesis statement (one that makes an argument), but you do need to tell readers what to expect. Try writing a simple statement that lets the reader know what is your main organizing principle. Here are a couple of examples:

The current trend in treatment for congestive heart failure combines surgery and medicine. More and more cultural studies scholars are accepting popular media as a subject worthy of academic consideration.

Consider organization

You’ve got a focus, and you’ve stated it clearly and directly. Now what is the most effective way of presenting the information? What are the most important topics, subtopics, etc., that your review needs to include? And in what order should you present them? Develop an organization for your review at both a global and local level:

First, cover the basic categories

Just like most academic papers, literature reviews also must contain at least three basic elements: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper. The following provides a brief description of the content of each:

• Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
• Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
• Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?

Organizing the body

Once you have the basic categories in place, then you must consider how you will present the sources themselves within the body of your paper. Create an organizational method to focus this section even further.

To help you come up with an overall organizational framework for your review, consider the following scenario:

You’ve decided to focus your literature review on materials dealing with sperm whales. This is because you’ve just finished reading Moby Dick, and you wonder if that whale’s portrayal is really real. You start with some articles about the physiology of sperm whales in biology journals written in the 1980’s. But these articles refer to some British biological studies performed on whales in the early 18th century. So you check those out. Then you look up a book written in 1968 with information on how sperm whales have been portrayed in other forms of art, such as in Alaskan poetry, in French painting, or on whale bone, as the whale hunters in the late 19th century used to do. This makes you wonder about American whaling methods during the time portrayed in Moby Dick, so you find some academic articles published in the last five years on how accurately Herman Melville portrayed the whaling scene in his novel.

Now consider some typical ways of organizing the sources into a review:

• Chronological: If your review follows the chronological method, you could write about the materials above according to when they were published. For instance, first you would talk about the British biological studies of the 18th century, then about Moby Dick, published in 1851, then the book on sperm whales in other art (1968), and finally the biology articles (1980s) and the recent articles on American whaling of the 19th century. But there is relatively no continuity among subjects here. And notice that even though the sources on sperm whales in other art and on American whaling are written recently, they are about other subjects/objects that were created much earlier. Thus, the review loses its chronological focus.
• By publication: Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on biological studies of sperm whales if the progression revealed a change in dissection practices of the researchers who wrote and/or conducted the studies.
• By trend: A better way to organize the above sources chronologically is to examine the sources under another trend, such as the history of whaling. Then your review would have subsections according to eras within this period. For instance, the review might examine whaling from pre-1600-1699, 1700-1799, and 1800-1899. Under this method, you would combine the recent studies on American whaling in the 19th century with Moby Dick itself in the 1800-1899 category, even though the authors wrote a century apart.
• Thematic: Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For instance, the sperm whale review could focus on the development of the harpoon for whale hunting. While the study focuses on one topic, harpoon technology, it will still be organized chronologically. The only difference here between a “chronological” and a “thematic” approach is what is emphasized the most: the development of the harpoon or the harpoon technology.But more authentic thematic reviews tend to break away from chronological order. For instance, a thematic review of material on sperm whales might examine how they are portrayed as “evil” in cultural documents. The subsections might include how they are personified, how their proportions are exaggerated, and their behaviors misunderstood. A review organized in this manner would shift between time periods within each section according to the point made.
• Methodological: A methodological approach differs from the two above in that the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the “methods” of the researcher or writer. For the sperm whale project, one methodological approach would be to look at cultural differences between the portrayal of whales in American, British, and French art work. Or the review might focus on the economic impact of whaling on a community. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed. Once you’ve decided on the organizational method for the body of the review, the sections you need to include in the paper should be easy to figure out. They should arise out of your organizational strategy. In other words, a chronological review would have subsections for each vital time period. A thematic review would have subtopics based upon factors that relate to the theme or issue.

Sometimes, though, you might need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. Put in only what is necessary. Here are a few other sections you might want to consider:

• Current Situation: Information necessary to understand the topic or focus of the literature review.
• History: The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
• Methods and/or Standards: The criteria you used to select the sources in your literature review or the way in which you present your information. For instance, you might explain that your review includes only peer-reviewed articles and journals.

Questions for Further Research: What questions about the field has the review sparked? How will you further your research as a result of the review?

Begin composing

Once you’ve settled on a general pattern of organization, you’re ready to write each section. There are a few guidelines you should follow during the writing stage as well. Here is a sample paragraph from a literature review about sexism and language to illuminate the following discussion:

However, other studies have shown that even gender-neutral antecedents are more likely to produce masculine images than feminine ones (Gastil, 1990). Hamilton (1988) asked students to complete sentences that required them to fill in pronouns that agreed with gender-neutral antecedents such as “writer,” “pedestrian,” and “persons.” The students were asked to describe any image they had when writing the sentence. Hamilton found that people imagined 3.3 men to each woman in the masculine “generic” condition and 1.5 men per woman in the unbiased condition. Thus, while ambient sexism accounted for some of the masculine bias, sexist language amplified the effect. (Source: Erika Falk and Jordan Mills, “Why Sexist Language Affects Persuasion: The Role of Homophily, Intended Audience, and Offense,” Women and Language19:2).

Use evidence

In the example above, the writers refer to several other sources when making their point. A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid.

Be selective

Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the review’s focus, whether it is thematic, methodological, or chronological.

Use quotes sparingly

Falk and Mills do not use any direct quotes. That is because the survey nature of the literature review does not allow for in-depth discussion or detailed quotes from the text. Some short quotes here and there are okay, though, if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Notice that Falk and Mills do quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. But if you find yourself wanting to put in more quotes, check with your instructor.

Summarize and synthesize

Remember to summarize and synthesize your sources within each paragraph as well as throughout the review. The authors here recapitulate important features of Hamilton’s study, but then synthesize it by rephrasing the study’s significance and relating it to their own work.

Keep your own voice

While the literature review presents others’ ideas, your voice (the writer’s) should remain front and center. Notice that Falk and Mills weave references to other sources into their own text, but they still maintain their own voice by starting and ending the paragraph with their own ideas and their own words. The sources support what Falk and Mills are saying.

Use caution when paraphrasing

When paraphrasing a source that is not your own, be sure to represent the author’s information or opinions accurately and in your own words. In the preceding example, Falk and Mills either directly refer in the text to the author of their source, such as Hamilton, or they provide ample notation in the text when the ideas they are mentioning are not their own, for example, Gastil’s. For more information, please see our handout on plagiarism .

Revise, revise, revise

Draft in hand? Now you’re ready to revise. Spending a lot of time revising is a wise idea, because your main objective is to present the material, not the argument. So check over your review again to make sure it follows the assignment and/or your outline. Then, just as you would for most other academic forms of writing, rewrite or rework the language of your review so that you’ve presented your information in the most concise manner possible. Be sure to use terminology familiar to your audience; get rid of unnecessary jargon or slang. Finally, double check that you’ve documented your sources and formatted the review appropriately for your discipline.

How To Write A Literature Review - A Complete Guide

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning to write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

• What sources do you need to answer these questions?

• What information do these sources contain?

• How can you use this information to answer your questions?

2. What to include in a literature review?

• A brief background of the problem or issue

• What has previously been done to address the problem or issue

• A description of what you will do in your project

• How this study will contribute to research on the subject

3. Why literature review is important?

The literature review is an important part of any research project because it allows the writer to look at previous studies on a topic and determine existing gaps in the literature, as well as what has already been done. It will also help them to choose the most appropriate method for their own study.

4. How to cite a literature review in APA format?

To cite a literature review in APA style, you need to provide the author's name, the title of the article, and the year of publication. For example: Patel, A. B., & Stokes, G. S. (2012). The relationship between personality and intelligence: A meta-analysis of longitudinal research. Personality and Individual Differences, 53(1), 16-21

5. What are the components of a literature review?

• A brief introduction to the topic, including its background and context. The introduction should also include a rationale for why the study is being conducted and what it will accomplish.

• A description of the methodologies used in the study. This can include information about data collection methods, sample size, and statistical analyses.

• A presentation of the findings in an organized format that helps readers follow along with the author's conclusions.

6. What are common errors in writing literature review?

• Not spending enough time to critically evaluate the relevance of resources, observations and conclusions.

• Totally relying on secondary data while ignoring primary data.

• Letting your personal bias seep into your interpretation of existing literature.

• No detailed explanation of the procedure to discover and identify an appropriate literature review.

7. What are the 5 C's of writing literature review?

• Cite - the sources you utilized and referenced in your research.

• Compare - existing arguments, hypotheses, methodologies, and conclusions found in the knowledge base.

• Contrast - the arguments, topics, methodologies, approaches, and disputes that may be found in the literature.

• Critique - the literature and describe the ideas and opinions you find more convincing and why.

• Connect - the various studies you reviewed in your research.

8. How many sources should a literature review have?

When it is just a chapter, sources should equal the total number of pages in your article's body. if it is a self-contained paper in itself, you need at least three times as many sources as there are pages in your work.

9. Can literature review have diagrams?

• To represent an abstract idea or concept

• To explain the steps of a process or procedure

• To help readers understand the relationships between different concepts

10. How old should sources be in a literature review?

Sources for a literature review should be as current as possible or not older than ten years. The only exception to this rule is if you are reviewing a historical topic and need to use older sources.

11. What are the types of literature review?

• Argumentative review

• Integrative review

• Methodological review

• Systematic review

• Meta-analysis review

• Historical review

• Theoretical review

• Scoping review

• State-of-the-Art review

12. Is a literature review mandatory?

Yes. Literature review is a mandatory part of any research project. It is a critical step in the process that allows you to establish the scope of your research, and provide a background for the rest of your work.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Here's why students love Scribbr's proofreading services

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Literature reviews

Writing a literature review.

The following guide has been created for you by the  Student Learning Advisory Service . For more detailed guidance and to speak to one of our advisers, please book an  appointment  or join one of our  workshops . Alternatively, have a look at our  SkillBuilder  skills videos.   

Preparing a literature review involves:

• Searching for reliable, accurate and up-to-date material on a topic or subject
• Reading and summarising the key points from this literature
• Synthesising these key ideas, theories and concepts into a summary of what is known
• Discussing and evaluating these ideas, theories and concepts
• Identifying particular areas of debate or controversy
• Preparing the ground for the application of these ideas to new research

Finding and choosing material

Ensure you are clear on what you are looking for. ask yourself:.

• What is the specific question, topic or focus of my assignment?
• What kind of material do I need (e.g. theory, policy, empirical data)?
• What type of literature is available (e.g. journals, books, government documents)?

What kind of literature is particularly authoritative in this academic discipline (e.g. psychology, sociology, pharmacy)?

How much do you need?

This will depend on the length of the dissertation, the nature of the subject, and the level of study (undergraduate, Masters, PhD). As a very rough rule of thumb – you may choose 8-10 significant pieces (books and/or articles) for an 8,000 word dissertation, up to 20 major pieces of work for 12-15,000 words, and so on. Bear in mind that if your dissertation is based mainly around an interaction with existing scholarship you will need a longer literature review than if it is there as a prelude to new empirical research. Use your judgement or ask your supervisor for guidance.

Where to find suitable material

Your literature review should include a balance between substantial academic books, journal articles and other scholarly publications. All these sources should be as up-to-date as possible, with the exception of ‘classic texts’ such as major works written by leading scholars setting out formative ideas and theories central to your subject. There are several ways to locate suitable material:

Module bibliography: for undergraduate dissertations, look first at the bibliography provided with the module documentation. Choose one or two likely looking books or articles and then scan through the bibliographies provided by these authors. Skim read some of this material looking for clues: can you use these leads to identify key theories and authors or track down other appropriate material?

Library catalogue search engine: enter a few key words to capture a range of items, but avoid over-generalisations; if you type in something as broad as ‘social theory’ you are likely to get several thousand results. Be more specific: for example, ‘Heidegger, existentialism’. Ideally, you should narrow the field to obtain just a few dozen results. Skim through these quickly to identity texts which are most likely to contribute to your study.

Library bookshelves: browse the library shelves in the relevant subject area and examine the books that catch your eye. Check the contents and index pages, or skim through the introductions (or abstracts, in the case of journal articles) to see if they contain relevant material, and replace them if not. Don’t be afraid to ask one of the subject librarians for further help. Your supervisor may also be able to point you in the direction of some of the important literature , but remember this is your literature search, not theirs.

Online: for recent journal articles you will almost certainly need to use one of the online search engines. These can be found on the ‘Indexing Services’ button on the Templeman Library website. Kent students based at Medway still need to use the Templeman pages to access online journals, although you can get to these pages through the Drill Hall Library catalogue. Take a look as well at the Subject Guides on both the Templeman and DHL websites.

Check that you have made the right selection by asking:

• Has my search been wide enough to ensure that I have identified all the relevant material, but narrow enough to exclude irrelevant material?
• Is there a good enough sample of literature for the level (PhD, Masters, undergraduate) of my dissertation or thesis?
• Have I considered as many alternative points of view as possible?
• Will the reader find my literature review relevant and useful?

Assessing the literature

Read the material you have chosen carefully, considering the following:

• The key point discussed by the author: is this clearly defined
• What evidence has the author produced to support this central idea?
• How convincing are the reasons given for the author’s point of view?
• Could the evidence be interpreted in other ways?
• What is the author's research method (e.g. qualitative, quantitative, experimental, etc.)?
• What is the author's theoretical framework (e.g. psychological, developmental, feminist)?
• What is the relationship assumed by the author between theory and practice?
• Has the author critically evaluated the other literature in the field?
• Does the author include literature opposing their point of view?
• Is the research data based on a reliable method and accurate information?
• Can you ‘deconstruct’ the argument – identify the gaps or jumps in the logic?
• What are the strengths and limitations of this study?
• What does this book or article contribute to the field or topic?
• What does this book or article contribute to my own topic or thesis?

As you note down the key content of each book or journal article (together with the reference details of each source) record your responses to these questions. You will then be able to summarise each piece of material from two perspectives:     

Content: a brief description of the content of the book or article. Remember, an author will often make just one key point; so, what is the point they are making, and how does it relate to your own research project or assignment?

Critical analysis: an assessment of the relative strengths and weaknesses of the evidence used, and the arguments presented. Has anything conveniently been left out or skated over? Is there a counter-argument, and has the author dealt with this adequately? Can the evidence presented be interpreted another way? Does the author demonstrate any obvious bias which could affect their reliability? Overall, based on the above analysis of the author’s work, how do you evaluate its contribution to the scholarly understanding and knowledge surrounding the topic?    

Structuring the literature review

In a PhD thesis, the literature review typically comprises one chapter (perhaps 8-10,000 words), for a Masters dissertation it may be around 2-3,000 words, and for an undergraduate dissertation it may be no more than 2,000 words. In each case the word count can vary depending on a range of factors and it is always best, if in doubt, to ask your supervisor.

The overall structure of the section or chapter should be like any other: it should have a beginning, middle and end. You will need to guide the reader through the literature review, outlining the strategy you have adopted for selecting the books or articles, presenting the topic theme for the review, then using most of the word limit to analyse the chosen books or articles thoroughly before pulling everything together briefly in the conclusion.

Some people prefer a less linear approach. Instead of simply working through a list of 8-20 items on your book review list, you might want to try a thematic approach, grouping key ideas, facts, concepts or approaches together and then bouncing the ideas off each other. This is a slightly more creative (and interesting) way of producing the review, but a little more risky as it is harder to establish coherence and logical sequencing.

Whichever approach you adopt, make sure everything flows smoothly – that one idea or book leads neatly to the next. Take your reader effortlessly through a sequence of thought that is clear, accurate, precise and interesting. 

Writing up your literature review

As with essays generally, only attempt to write up the literature review when you have completed all the reading and note-taking, and carefully planned its content and structure. Find an appropriate way of introducing the review, then guide the reader through the material clearly and directly, bearing in mind the following:

• Be selective in the number of points you draw out from each piece of literature; remember that one of your objectives is to demonstrate that you can use your judgement to identify what is central and what is secondary.
• Summarise and synthesise – use your own words to sum up what you think is important or controversial about the book or article.
• Never claim more than the evidence will support. Too many dissertations and theses are let down by sweeping generalisations. Be tentative and careful in the way you interpret the evidence.
• Keep your own voice – you are entitled to your own point of view provided it is based on evidence and clear argument.
• At the same time, aim to project an objective and tentative tone by using the 3rd person, (for example, ‘this tends to suggest’, ‘it could be argued’ and so on).
• Even with a literature review you should avoid using too many, or overlong, quotes. Summarise material in your own words as much as possible. Save the quotes for ‘punch-lines’ to drive a particular point home.
• Revise, revise, revise: refine and edit the draft as much as you can. Check for fluency, structure, evidence, criticality and referencing, and don’t forget the basics of good grammar, punctuation and spelling.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

How to write a Literature Review?

Components:

• Introduction: State your research topic
• Body/Presentation of Sources Used: A research topic have different angles/viariables/themes. Organize your finding based of those categories.
• Discussion/Analysis of Literature: Summarize/synthesize major literature that deal with your research topic. Discuss common themes, gaps, etc...
• Conclusion: Re-state your topic and explain if it has changed after the review and what are the next steps for your research
• Do not over "quote." If you only quote from every single author you found, then you are not showing any original thinking or analysis. Use quotes judiciously. Use quotes to highlight a particular passages or thought that is exemplary of the research, theory or topic you are researching.
• Instead use paraphrasing to report, in your own words, what the author was reporting or theorizing.
• Summarize findings, important sections or a whole article--this is different from paraphrasing since you are not re-stating the author words but identifying the main points of what you are reading in a concise matter for your readers.
• When synthesizing your findings for the literature review (this is when make comparison, establish relationships between authors' works, point out weakness, strenghts and gaps among the literature review, you still need to give credit to these sources.

Definitions:

Quoting* : "(a) to speak or write (a passage) from another usually with credit acknowledgment. (b) to repeat a passage from especially in substantiation or illustration."

Paraphrasing* : Paraphrase is the “ restatement of a text, passage, or work giving the meaning in another form.”  

Summarize *: It’s the process of summarizing a text or paragraph to its the main points succinctly.

Synthesize *: “1. (a) the composition or combination of parts or elements so as to form a whole."

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Quotes & Sayings About Review Of Literature

Enjoy reading and share 38 famous quotes about Review Of Literature with everyone.

Top Review Of Literature Quotes

A lot of the reason the Universal version of 'Heights' went away is that they were afraid they didn't have a big enough Latino star to bankroll this movie. The people I dealt with at the studio who wanted to make this movie were very passionate about it. — Lin-Manuel Miranda

MERCER USED TO PASS THE TIME, during his post-grad months of flipping burgers out on Route 17, by polishing his opinions on life and literature for that future date when they would grace the pages of The Paris Review. — Garth Risk Hallberg

Perhaps the critics are right: this generation may not produce literature equal to that of any past generation who cares? The writer will be dead before anyone can judge him but he must go on writing, reflecting disorder, defeat, despair, should that be all he sees at the moment, but ever searching for the elusive love, joy, and hope qualities which, as in the act of life itself, are best when they have to be struggled for, and are not commonly come by with much ease, either by a critic's formula or by a critic's yearning. — Bill Styron

Usually, when you go to a movie, your consciousness floats above the film. 3D sucks you in and makes it a visceral experience. — James Cameron

I never eat meat as I think it is wrong to deprive animals of their life when they are so difficult to chew anyway — Leonora Carrington

The literature [Nobel] laureate of this year has said that an author can do anything as long as his readers believe him. A scientist cannot do anything that is not checked and rechecked by scientists of this network before it is accepted. — Sune Bergstrom

All a starred review amounts to is an expression of brand loyalty, an assertion of personal preference for one brand of literature above another. It is as hopelessly beside the point as giving four stars to your mother, three stars to your childhood, or two stars to your cat. — Eleanor Catton

The novels that get praised in the NY Review of Books aren't worth reading. Ninety-seven percent of science fiction is adolescent rubbish, but good science fiction is the best and only literature of our times. — Robert Anton Wilson

Science can only state what is, not what should be. — Albert Einstein

You don't want a general houseworker, do you? Or a traveling companion, quiet, refined, speaks fluent French entirely in the present tense? Or an assistant billiard-maker? Or a private librarian? Or a lady car-washer? Because if you do, I should appreciate your giving me a trial at the job. Any minute now, I am going to become one of the Great Unemployed. I am about to leave literature flat on its face. I don't want to review books any more. It cuts in too much on my reading. — Dorothy Parker

Big results require big ambitions. ~ Heraclitus — B.L. Norris

On the pitch, I argue, I shout, I talk rubbish and generally do anything I can to get ahead. — Luis Suarez

I can't see either of these papers being in the next IPCC report. Kevin [Trenberth] and I will keep them out somehow, even if we have to redefine what the peer-review literature is! — Phil Jones

How can you say one thing when your data shows something else. One doesn't know what was on the authors' minds and maybe they interpreted things differently but the sense is that the literature maintains an attitude somewhat like the approach of lawyers. If the jury buys it, it doesn't matter whether or not it's true. In scientific publishing, the jury are the reviewers and the editors. If they are already convinced of the conclusion, if there is no voir dire, you will surely win the case. — Richard David Feinman

Aspiring writers should read the entire canon of literature that precedes them, back to the Greeks, up to the current issue of The Paris Review. — William Kennedy

When I wrote about Mary Wollstonecraft, I found that here she was, in the late 18th century, going to work for the 'Analytical Review.' What was the 'Analytical Review?' It was a magazine that dealt with politics and literature. — Claire Tomalin

Stories are the only things that give any meaning to our pointless, shapeless lives." "Literature above all is a mode of transport. It lifts you up out of whatever situation you're in and it puts you down somewhere else. It fucking escapes you. That's what literature is." -Jumping Off a Cliff: An Interview with Kevin Barry, the Paris Review. November 2013 — Kevin Barry

We sometimes reveal how ignorant or bored we were when we read a book by giving it 5-stars. — Mokokoma Mokhonoana

Literature should not be exclusive, it should be inclusive. My general view is that you can't, based on your own experience, project what a book will do for someone else. That's why I don't review books. — Richard Ford

She was a great and insatiable reader, surprisingly well acquainted with the classics of literature, and unexpectedly lavish in the purchase of books. Her neighbours never forgot to mention, in describing her, the awe-inspiring fact that she 'took in the English Times and the Saturday Review, and read every word of them,' but it was hinted that the bookshelves that her own capable hands had put up in her bedroom held a large proportion of works of fiction of a startlingly advanced kind, 'and,' it was generally added in tones of mystery, 'many of them French. — Edith Somerville

[He] made me feel ... large, maybe. In a way I hadn't before. But he didn't know that. For all he knew, I was always that large. It felt good. Fun. Unexpectedly large is sudden, magic levitation - you're high, an impervious Balloon of Joy. — Deb Caletti

Perhaps if more people realized that coupling in higher organisms is fundamentally about bonding, not only about the drive to reproduce, there would be less prejudice against homosexuality. In fact, homosexuality is natural and common in the animal kingdom. In a 2009 review of the scientific literature, University of California at Riverside biologists Nathan W. Bailey and Marlene Zuk, who advocate more study about the evolutionary impetus for homosexual behavior, state, The variety and ubiquity of same-sex sexual behavior in animals is impressive; many thousands of instances of same-sex courtship, pair bonding and copulation have been observed in a wide range of species, including mammals, birds, reptiles, amphibians, insects, mollusks, and nematodes. — Bruce H. Lipton

Horror. I can't manage it. I become well horrified. Self-help books have a similar effect. When asked, "Any literary genre you simply can't be bothered with?" - (By the Book: Writers on Literature and the Literary Life from the NYT Book Review, by Pamela Paul) — Emma Thompson

What do researchers know? What do they not know? What has been researched and what has not been researched? Is the research reliable and trustworthy? Where are the gaps in the knowledge? When you compile all that together, you have yourself a literature review. — Jim Ollhoff

Limits the Romans' anxieties to two things - bread and games. — Juvenal

I majored in journalism at Arizona State University, where I began writing the columns I write now, but I cannot, in good conscience, refer to myself as a writer. I'm a columnist, maybe a journalist, I guess I'm an author, but writer ... no. That's not up to me to call myself, that's rather lofty. It's for the reader to decide. — Laurie Notaro

A review of the psychological literature suggests that mindfulness in particular fosters many components of physical and mental health: It improves immune function, blood pressure, and cortisol levels; it reduces anxiety, depression, neuroticism, and emotional reactivity. It also leads to greater behavioral regulation and has shown promise in the treatment of addiction and eating disorders. Unsurprisingly, the practice is associated with increased subjective well-being.13 — Sam Harris

Without mathematics, your world becomes foggy! For a clear vision, you need to be educated in the Temple of Mathematics! — Mehmet Murat Ildan

I cherish the review-as-literature; as lapidary journalism in the eighteenth-century mode, the last hard sparkling diamond in theessayists's tarnished crown. To me, writing a good review is not just a way to make extra money, but a sacred duty. — Florence King

We never begin worship. We aim it. — Matt Papa

It is how people respond to stress that determines whether they will profit from misfortune or be miserable. — Mihaly Csikszentmihalyi

The kindest thing you can offer an author is a review and a star rating. So appreciated. THE GOLDEN PEACOCK has had a successful 5-star run on Goodreads and on Amazon. Thank you!" Lauren B. Grossman — Lauren B. Grossman

The two sexes are different to the core, and each is necessary - culturally and biologically - for the optimal development of a human being."12 In a summary of the relevant science, University of Virginia sociologist W. Bradford Wilcox finds much the same: Let me now conclude our review of the social scientific literature on sex and parenting by spelling out what should be obvious to all. The best psychological, sociological, and biological research to date now suggests that - on average - men and women bring different gifts to the parenting enterprise, that children benefit from having parents with distinct parenting styles, and that family breakdown poses a serious threat to children and to the societies in which they live.13 — Sherif Girgis

A good critic is trying to tell you what she has learned about herself from the reading of a particular piece of literature. A bad reviewer is often trying to tell you how smart he is by declaring whether or not he liked a particular book. If he liked the book, then this is the kind of book a superior person likes, and vice versa. He might try to explain why he didn't like it, but the review is really just a tautology. "I didn't like this book because it is bad," is equivalent to "This book is bad because I didn't like it. — Kevin Guilfoile

(50 liters of O2 makes 100 liters of molecules that only have one O each). — Andy Weir

If you've got a big gut and you start doing sit-ups, you are going to get bigger because you build up the muscle. You've got to get rid of that fat! How do you get rid of fat? By changing your diet. — Jack LaLanne

I still maintain that the times get precisely the literature that they deserve, and that if the writing of this period is gloomy the gloom is not so much inherent in the literature as in the times. — Bill Styron

The American critic Dale Peck, author of Hatchet Jobs (2004), argues that reviewing finds its true character in critical GBH such as Fischer's [review of Martin Amis's Yellow Dog]. It represents a return to the prehistoric origins of reviewing in Zoilism - a kind of pelting of pretentious literature with dung, lest the writers get above themselves; it is to the novelist what the gown of humiliation was to the Roman politician - a salutary ordeal. Less grandly, bad reviews are fun, so long as you are not the author. There is, it must be admitted, a kind of furtive blood sport pleasure in seeing a novelist suffer. You read on. Whereas most of us stop reading at the first use of the word 'splendid' or 'marvellous' in a review. — John Sutherland

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

• PNG larger image
• TIFF original image

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

https://doi.org/10.1371/journal.pcbi.1003149.g001

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Best can you use quotes in a literature review

Home » Quotes » Best can you use quotes in a literature review

A literature review is an essential part of any academic research paper or dissertation. It involves a comprehensive analysis and evaluation of existing literature on a specific topic. One common question that arises when writing a literature review is whether it is appropriate to use quotes. In this article, we will explore the use of quotes in a literature review and provide some guidelines for their effective use.

Using quotes in a literature review can be a powerful tool to support your arguments and provide evidence for your claims. Quotes allow you to directly cite the author’s words and ideas, adding credibility to your own analysis. They can also help you highlight key points or concepts from the literature that are relevant to your research. However, it is important to use quotes sparingly and appropriately to avoid plagiarism and maintain the flow of your writing.

When deciding whether to use quotes in a literature review, consider the following factors:

• The significance of the author’s words: If a particular quote encapsulates an important idea or argument, it may be worth including in your review.
• The relevance to your research: Quotes should be directly related to the topic you are discussing and provide valuable insights or evidence.
• The quality of the quote: Ensure that the quote is from a reputable source and accurately represents the author’s intended meaning.

Using Literary Quotations

Use the guidelines below to learn how to use literary quotations.

Download this Handout PDF

Introduction

When you’re asked to write a paper analyzing a work of literature, your instructor probably expects you to incorporate quotations from that literary text into your analysis. But how do you do this well? What kind of quotations do you use? How do you seamlessly weave together your ideas with someone else’s words?

On this page we clarify the purpose of using literary quotations in literary analysis papers by exploring why quotations are important to use in your writing and then explaining how to do this. We provide general guidelines and specific suggestions about blending your prose and quoted material as well as information about formatting logistics and various rules for handling outside text.

Although this material is focused on integrating your ideas with quotations from novels, poems, and plays into literary analysis papers, in some genres this advice is equally applicable to incorporating quotations from scholarly essays, reports, or even original research into your work.

For further information, check out our Quoting and Paraphrasing resource, or you may wish to see when the Writing Center is offering its next introductory workshop about the genre of literary analysis. Additionally, our Short Guide to Close Reading for Literary Analysis offers wonderful insight into how you can read a piece of literature in order to analyze it.

Why should I use literary quotations?

Within a literary analysis, your purpose is to develop an argument about what the author of the text is doing—how the text “works.” You use quotations to support this argument. This involves selecting, presenting, and discussing material from the text in order to “prove” your point—to make your case—in much the same way a lawyer brings evidence before a jury.

Quoting for any other purpose is counterproductive. Don’t quote to “tell the story” or otherwise convey basic information about the text; most of the time within this genre you can assume your reader knows the text. And don’t quote just for the sake of quoting or to fill up space.

How do I use literary quotations?

General guidelines.

The following paragraph is from a student’s analysis of the relationship between two characters in Woolf’s To the Lighthouse . Notice how statements expressing the writer’s ideas and observations are verified with evidence from the novel in both summarized and quoted form.

We learn about Mrs. Ramsey’s personality by observing her feelings about other characters. For example, Mrs. Ramsey has mixed feelings toward Mr. Tansley, but her feelings seem to grow more positive over time as she comes to know him better. At first Mrs. Ramsey finds Mr. Tansley annoying, as shown especially when he mentions that no one is going to the lighthouse (7). But rather than hating him, she feels pity: “she pitied men always as if they lacked something . . .” (85). Then later, during the gathering, pity turns to empathy as she realizes that Mr. Tansley must feel inferior. He must know, Mrs. Ramsey thinks, that “no woman would look at him with Paul Rayley in the room” (104). Finally, by the end of the dinner scene, she feels some attraction to Mr. Tansley and also a new respect: “She liked his laugh . . . She liked his awkwardness. There was a lot in that man after all” (110). In observing this evolution in her attitude, we learn more about Mrs. Ramsey than we do about Mr. Tansley. The change in Mrs. Ramsey’s attitude is not used by Woolf to show that Mrs. Ramsey is fickle or confused; rather it is used to show her capacity for understanding both the frailty and complexity of human beings. This is a central characteristic of Mrs. Ramsey’s personality.

Your ideas + textual evidence + discussion

Notice that this paragraph includes three basic kinds of materials: (a) statements expressing the student’s own ideas about the relationship Woolf is creating; (b) data or evidence from the text in summarized, paraphrased, and quoted form; and (c) discussion of how the data support the writer’s interpretation. All the quotations are used in accordance with the writer’s purpose, i.e., to show how the development of Mrs. Ramsey’s feelings indicates something about her personality.

Textual evidence options

Quoting is only one of several ways to present textual material as evidence. You can also refer to textual data, summarize, and paraphrase. You will often want merely to refer or point to passages (as in the third sentence in the above example paragraph) that contribute to your argument. In other cases, you will want to paraphrase, i.e., “translate” the original into your own words, again instead of quoting. Summarize or paraphrase when it is not so much the language of the text that justifies your position, but the substance or content.

Quoting selectively

Similarly, after you have decided that you want to quote material, quote only the portions of the text specifically relevant to your point . Think of the text in terms of units—words, phrases, sentences, and groups of sentences (paragraphs, stanzas)—and use only the units you need. If it is particular words or phrases that “prove” your point, you do not need to quote the full sentences they appear in; rather, incorporate the words and phrases into your own sentences that focus on your own ideas.

Blending your prose and quoted material

It is permissible to quote an entire sentence (between two sentences of your own), but in general you should avoid this method of bringing textual material into your discussion. Instead, use one of the following patterns:

An introducing phrase or orienter plus the quotation:

• In Blake’s poem “The Tyger,” it is creation, not a hypothetical creator, that is supremely awesome. [ argument sentence ]. The speaker asks, “What immortal hand or eye / Dare frame thy fearful symmetry?” [ data sentence; orienter before quote ]
• Gatsby is not to be regarded as a personal failure. [ argument sentence ] “Gatsby turned out all right at the end” (2), according to Nick. [ data sentence; orienter after quote ]
• “Our baby was a boy,” Shukumar tells his wife in the conclusion of Lahiri’s “A Temporary Matter” (22). [ data sentence; orienter after quote ] This admission is a death knell, tolling the end of their failing marriage. [ argument sentence ]

An assertion of your own and a colon plus the quotation:

• In the midst of discussing the fate of the Abame tribe, Uchendu presents his own theory: “There is no story that is not true” (141).
• Fitzgerald gives Nick a muted tribute to the hero: “Gatsby turned out all right at the end” (2).
• Within Othello , Cassio represents not only a political but also a personal threat to Iago: “He hath a daily beauty in his life / That makes me ugly . . .” (5.1.19-20).

An assertion of your own with quoted material worked in:

• For Nick, who remarks that Gatsby “turned out all right” (2), the hero deserves respect but perhaps does not inspire great admiration.
• Satan’s motion is many things; he “strides” through the air (55), arrives like a “rattling” cloud (56), and later explodes—“wandering,” “hovering and blazing” like a fire (270).
• Walking through Geraldine’s house, Pecola “wanted to see everything slowly, slowly” in order to fully appreciate its comparative order and opulence (Morrison 89).

Maintaining clarity and readability

Introduce a quotation either by indicating what it is intended to show, by naming its source, or by doing both. For non-narrative poetry, it’s customary to attribute quotations to “the speaker”; for a story with a narrator, to “the narrator.” For plays, novels, and other works with characters, identify characters as you quote them.

Do not use two quotations in a row without intervening text of your own. You should always be contextualizing all of your outside material with your own ideas, and if you let quotes build up without a break, readers will lose track of your argument.

Using the correct verb tense is a tricky issue. It’s customary in literary analysis to use the present tense; this is because it is at the present time that you (and your reader) are looking at the text. But events in a narrative or drama take place in a time sequence. You will often need to use a past tense to refer to events that took place before the moment you are presently discussing. Consider this example:

When he hears Cordelia’s answer, King Lear seems surprised, but not dumbfounded. He advises her to “mend [her] speech a little.” He had expected her to praise him the most; but compared to her sisters’, her remarks seem almost insulting (1.1.95).

Formatting logistics and guidelines

If for the sake of brevity you wish to omit material from a quoted passage, use ellipsis points (three spaced periods) to indicate the omission. Notice how in the paragraph about To the Lighthouse , above, the writer quoted only those portions of the original sentences that related to the point of the analysis.

When quoting, you may alter grammatical forms such as the tense of a verb or the person of a pronoun so that the quotation conforms grammatically to your own prose; indicate these alterations by placing square brackets around the changed form. In the quotation about King Lear at the end of the previous section, “her” replaces the “your” of the original so that the quote fits the point of view of the paper (third person).

Reproduce the spelling, capitalization, and internal punctuation of the original exactly. Of the following sentences presenting D. H. Lawrence’s maxim, “Books are not life,” the first is not acceptable in some style systems.

• For Lawrence, “books are not life.” [ UNACCEPTABLE ]
• For Lawrence, “[b]ooks are not life.” [ acceptable but awkward ]
• Lawrence wrote, “Books are not life.” [ acceptable ]
• “Books,” Lawrence wrote, “are not life.” [ acceptable ]
• For Lawrence, books “are not life.” [ acceptable ]

Punctuation

You may alter the closing punctuation of a quotation in order to incorporate it into a sentence of your own. For example:

• “Books are not life,” Lawrence emphasized.

Commas and periods go inside the closing quotation marks; the other punctuation marks go outside. For example:

• Lawrence insisted that books “are not life”; however, he wrote exultantly about the power of the novel.
• Why does Lawrence need to point out that “Books are not life”?

When quoting lines of poetry up to three lines long (which are not indented), separate one line of poetry from another with a slash mark with a space on either side (see examples from Blake’s “The Tyger” and Shakespeare’s Othello above).

Indentation

Prose or verse quotations less than four lines long are not indented. For quotations of this length, use the patterns described above.

“Longer” quotations should be formatted according to the expectations of a block quote. This unit of text should be positioned one half inch from the left margin, and opening and closing quotation marks are not used. The MLA Handbook , 8 th edition (2016) recommends that indented quotations be double-spaced, but many instructors prefer them single-spaced. The meaning of “longer” varies slightly from one style system to another, but a general rule is to indent quotations that are more than two (or three) lines of verse or four lines of prose.

If you’re quoting a series of dialogue dialogue between characters in a play, indent these lines and place the speaker’s name before the speech quoted. For example:

• CAESAR: Et tu, Brute! Then, fall, Caesar! CINNA: Liberty! Freedom! Tyranny is dead! (3.1.77-78)

Documentation

Follow your course instructor’s guidelines for documenting sources. If your instructor hasn’t told you which system to use to document sources, ask.

The documentation style used in this handout is that presented in the MLA Handbook , 8 th edition (2016), the most common citation style for literary analysis papers. The Writing Center has information about the rules of documentation within the most common systems .

Direct Quotations v Summary v Paraphrasing

• Introduction
• Direct Quotations
• Paraphrasing
• Common Knowledge

THE BASICS:

• Cite when referencing a source and stating someone else's ideas, research, opinions, or thoughts
• Cite when using an image, media file, document, or just about anything you did not create yourself.

• Direct quotation

IT IS NOT NECESSARY TO CITE THE FOLLOWING:

• Your thoughts, explanations, and interpretations
• Common knowledge

This Libguide section was inspired by one at Butler University, who graciously agreed to share their work.

" Quotations must be identical to the original, using a narrow segment of the source. They must match the source document word for word and must be attributed to the original author" (Driscoll & Brizee, 2013).

This quotation is taken word for word from the Purdue Online Writing Lab. Since the OWL's exact words are being used, credit is given to the authors, Driscoll & Brizee, using an in-text citation.  An entry would also be made in the paper's reference list as follows:

WHEN IS A DIRECT QUOTE APPROPRIATE?

Most of the time, summarizing or paraphrasing is a better choice.  Direct quotes are best under the following circumstances:

• When the phrasing is unique or strengthens your argument
• When the essence or meaning of the text would be lost if summarized or paraphrased
• When you want to invoke the authority of the author, and that authority is emphasized through the author's exact words.

WHEN USING A  DIRECT QUOTE ...

• Use quotation marks around all words copied from a source.
• Follow formatting guidelines for using short or long (more than 40 words) quotations.
• Provide an in-text citation for the source of the exact words you used immediately after the quotation
• List a complete citation for the source on your references page.

STILL HAVE QUESTIONS?

• Check out the Harvard Guide to Using Sources, " When and How Much to Quote ."

DEFINITION OF SUMMARY

"A summary involves Involves putting the main idea(s) into your own words, including only the main point(s).... Summaries are significantly shorter than the original and take a broad overview of the source material" (Driscoll & Brizee, 2013).

The passage above is a direct quotation from the Purdue OWL.  Now take a look at that same passage, which has been summarized, or which restates the most important ideas in the writer's own words.  A summary is usually much shorter than the original passage:

Summaries are short restatements of main ideas.

WHEN SHOULD SUMMARY BE USED?

• To provide useful background information for your audience
• When concise, general, broad information is all that is needed

HOW TO INCLUDE SUMMARY PROPERLY IN YOUR WRITING

• Since you are not directly quoting an author word-for-word, there is no need for quotation marks around your summary.
• Credit the source with an in-text citation;  be aware that APA requests you provide a page or paragraph number whenever available.

DEFINITION OF PARAPHRASE:

"A  paraphrase is a detailed restatement in your own words of a written or sometimes spoken source material. Apart from the changes in organization, wording, and sentence structure, the paraphrase should be nearly identical in meaning to the original passage. It should also be near the same length as the original passage and present the details of the original." University of Houston-Victoria Student Success Center (n.d.). Decide when to Quote, Paraphrase & Summarize.

Paraphrasing is "your own rendition of essential information and ideas expressed by someone else, presented in a new form."   Purdue University Online Writing Lab. (2012).  Quoting, Paraphrasing, and Summarizing

Let's look at how a writer would paraphrase the definition from the Purdue OWL.

When you paraphrase, you take a passage from a source and put it into your own words. The original source must still be cited. Usually, the paraphrased version will be shorter than the original (Driscoll and Brizee, 2013).

Even though the paraphrased version isn't exactly the same as the source quotation, the idea is still the same. Therefore, it's important to give credit to the original writers.

Information in this section provided by Butler University http://libguides.butler.edu/c.php?g=34302&p=218282 and by National Louis University http://libguides.nl.edu/content.php?pid=16608&sid=5360442

WHEN PARAPHRASING ...

• Paraphrase an author's words by stating his or her ideas in your own words with your own phrasing.  Be sure to change both the sentence structure and wording.
• Compare your paraphrased writing with the author's exact words to make sure you have not copied phrases or sentences from the author.
• Always provide a citation for the paraphrased ideas.

PARAPHRASING versus SUMMARY:  WHAT'S THE DIFFERENCE?

Similarities

• Both involve a restatement of the original author's ideas and words. 
• Both require that you, the writer, give credit to the original source. 
• Both require that what you end up writing sounds more like you than the original author.

Differences 

• A paraphrase is a restatement that accurately represents the ideas in an author's original work, using your unique phrasing and vocabulary.
• A summary condenses the original author's words into just a few main ideas.  It is meant to be short.
• The main difference lies in purpose.   A paraphrase should focus on communicating the source material in a way that sounds uniquely like the writer who is restating the ideas.  Length is not a concern.  A summary is designed to capture the main idea of source material in brief form.
• Purdue Owl:  " Quoting, Paraphrasing, and Summarizing ."

DEFINITION OF COMMON KNOWLEDGE

Common knowledge is information that is considered widely known or can be easily verified. 

Common knowledge does not need to be cited.

EXAMPLES OF COMMON KNOWLEDGE

• Thomas Jefferson wrote the Declaration of Independence.
• Water freezes around 32 degree Fahrenheit.
• The Great Lakes are located in the Midwest.
• Steve Jobs was the inventor of many Apple products.

CONSIDER YOUR AUDIENCE

What seems common to you may not be common to everyone, especially if the common knowledge to which you are referring is based primarily upon culture or geography.   For example, anyone who has taken basic American history knows about Thomas Jefferson's contributions to our nation, but someone who has been raised elsewhere and who immigrated to the US later may not have that same background knowledge.   In those cases, it is helpful to refer readers to outside sources for that information so they may pursue the topics on their own.

How to Quote

• Fewer than 40 Words
• 40 or More Words
• When you need to leave out part of a quotation to make it fit grammatically or because it contains irrelevant/unnecessary information, insert ellipses like this  . . .  to indicate the truncation.
• If you must add or slightly change words within a quotation for reasons of grammar or clarity, indicate the change with square brackets. Exception: It is acceptable to change double quotation marks to single ones when you have a quotation within a quotation; it is also fine to change the first word of a quotation to upper case when needed.

See pages 170-171 of the APA manual for more information.

Because they are an avenue to communicating a specific point, "quotations are effective in research papers when used selectively" (Gibaldi, 2003, p.109).

See pages 170-171 of the manual for more information.

40 Words or More

• Omit the quotation marks.
• Start a block quotation on a new line.
• Indent the entire quotation a half inch from the left margin (but not from the right margin).
• Double space the quotation.
• Place punctuation mark immediately after the quotation.

Quoting - Frequently Asked Questions

• How do I quote when there are no page numbers? If the page numbers are not provided, use paragraph numbers in your citation with abbreviation para . E xample: Research has clearly shown that "dogs drool often" (Jones, 2009, para. 2).  
• How do I indicate I have omitted part of the text?
• Use three spaced ellipsis points like this  . . .  within a sentence when you omit material from the original work.
• Use four points like this  . . . .  when you have omitted material between two sentences.

See page 173 of the manual for more information.

How to Cite

• 1-2 authors
• 3-5 authors

APA Style requires that you cite an author within the body of your paper in addition to having a full citation on the references page. You can directly quote an author or paraphrase an author.

Paraphrasing versus Quoting

It is highly preferred that you use your own words to describe someone else's work, findings, etc. Although paraphrasing is preferred, you can directly quote from an author as long as you include the author's name, the date of publication, and the page number of the quotation. (Look to the right for more information about quoting.)

See pages 174-179 of the manual for more information.

See page 176 Table 6.1 for Basic Citation Styles.

One Author:  

• Paraphrasing: Cite author's last name and publication year.
• Quoting: Cite author's last name, publication year, and the page number(s)*. *On a website? Then cite the paragraph number after para .

Paraphrasing:  Flight is an ability many birds have (Smith, 2011).

Author’s Name is Part of a Sentence: According to Smith (2011), many birds have the ability to fly.

Quoting:  "Many birds can fly" (Smith, 2011, p. 265).

Institutional Author: "For an institutional author, spell out its entire name" (Center for Institutional Authors, 2016, para. 2).

Two Authors:

Use the word and between the authors' last names when citing within the text, and use the ampersand (i.e., &) when citing within the parentheses.

• Paraphrasing: Cite authors' last names and publication year.
• Quoting: Cite authors' last names, publication year, and the page number(s).

Paraphrasing:  The research indicated that weather temperature is positively correlated with crime incidence (Davis & Brown, 1995).

Authors’ Names are Part of a Sentence : David and Brown (1995) suggest that weather temperature is positively correlated with crime incidence.

Quoting:  Davis and Brown (1995) stated, "higher temperatures are correlated with an increase in criminal activity" (p. 180).

See pages 174-175 of the manual for more information.

Three to Five Authors:  

Name all the authors' last names the first time you cite them. Use the word and between the second to last and last authors' last names when citing within the text, and use the ampersand (i.e., &) when citing within the parentheses.

Use et al. for any subsequent citations.

• Quoting: Cite authors' last names, publication year, and the page number(s).

Authors’ Names are Part of Sentence:

First Time:  Research from Lee, Lewis, Taylor, Smith, and Johnson (2015) shows that librarians often have difficulty coming up examples of fake quotes to use in libguides.

All Other Times:  Lee et al. (2015) suggest that librarians often have difficulty creating examples of fake quotes to use in libguides.

Citation at End of Sentence:

First Time:  (Lee, Lewis, Taylor, Smith, & Johnson, 2015).

All Other Times:  (Lee et al., 2015).

***Include the page number after the year if you are using a direct quote.

See page 175 of the manual for more information.

Six or More Authors:  

Only give the first author's last name followed by et al . rather than listing each author's name.

• Paraphrasing: Cite first author's last name, et al., and publication year.
• Quoting: Cite first author's last name, et al., publication year, and the page number(s).

Part of Sentence: Torres et al. (2010) argued...

Citation at End of Sentence: (Torres et al., 2010).

How do I cite it when...?

1. There's no author

If there is no author (be sure it's not an institutional author, like Centers for Disease Control and Prevention), cite  the first few words of the reference list entry (usually the title) and the year. Use double quotation marks around the title or abbreviated title. For example: ("All 33 Chile Miners," 2010). Note: Use the full title if it is short.

2. Authors Have The Same Last Name

If two or more of your sources are written by authors with the same surname, include the first author's initials with the surname in every in-text reference.

Example:  Among studies, we review M. A. Light and Light (2008) and I. Light (2006) ... 

3. No Page Numbers Are Available for a Quotation

If a resource contains no page numbers, as can be the case with electronic sources, then you cannot include a page number in the parentheses. However, if the source indicates paragraph numbers, use the abbreviation “para.” and the relevant number in the parentheses. If the paragraph number is not visible, cite the closest heading and the paragraph number following it.

4 Citing When Quoting a Quote

APA strongly recommends that you cite the direct and original source. So, if you read something that cites an interesting piece of information, it's best to find that original source, read it, and cite it. This will also prevent you from incorrectly interpreting it. Now, if you need to quote and cite something that is quoted in the source you are reading, there is a method.

Jackson's study (as cited in Smith, 2009) suggests....

You would only need to cite "Smith" in your references page, since this is the author you have read.

5. Citing Multiple Sources At Once

When citing several sources at once, combine them all within one set of parentheses. List them in alphabetical order (by authors' last names) and date order (if necessary), using semicolons between them.

Example:  Many studies have found a significant correlation between writing papers early and getting a higher grade (Day & Dream, 2010; Light, 2008;  Night, Walker, & Sleep, 2015) .
