• Different subject areas
• Find literature reviews

When conducting your searches you may find many references that will not be suitable to use in your literature review.

• Skim through the resource - a quick read through the table of contents, the introductory paragraph or the abstract should indicate whether you need to read further or whether you can immediately discard the result.
• Evaluate the quality and reliability of the references you find - our page on evaluating information outlines what you need to consider when evaluating the books, journal articles, news and websites you find to ensure they are suitable for use in your literature review.

Critiquing the literature involves looking at the strength and weaknesses of the paper and evaluating the statements made by the author/s.

Analysis, synthesis, critique

Literature reviews build a story. You are telling the story about what you are researching. Therefore, a literature review is a handy way to show that you know what you are talking about. To do this, here are a few important skills you will need.

Skill #1: Analysis

Analysis means that you have carefully read a wide range of the literature on your topic and have understood the main themes, and identified how the literature relates to your own topic. Carefully read and analyze the articles you find in your search, and take notes. Notice the main point of the article, the methodologies used, what conclusions are reached, and what the main themes are. Most bibliographic management tools have capability to keep notes on each article you find, tag them with keywords, and organize into groups.

Skill #2: Synthesis

After you’ve read the literature, you will start to see some themes and categories emerge, some research trends to emerge, to see where scholars agree or disagree, and how works in your chosen field or discipline are related. One way to keep track of this is by using a Synthesis Matrix .

Skill #3: Critique

As you are writing your literature review, you will want to apply a critical eye to the literature you have evaluated and synthesized. Consider the strong arguments you will make contrasted with the potential gaps in previous research. The words that you choose to report your critiques of the literature will be non-neutral. For instance, using a word like “attempted” suggests that a researcher tried something but was not successful. For example: 

There were some attempts by Smith (2012) and Jones (2013) to integrate a new methodology in this process.

On the other hand, using a word like “proved” or a phrase like “produced results” evokes a more positive argument. For example:

The new methodologies employed by Blake (2014) produced results that provided further evidence of X.

In your critique, you can point out where you believe there is room for more coverage in a topic, or further exploration in in a sub-topic.

• Writing a Critical Review

Writing a Critique

A critique (or critical review) is not to be mistaken for a literature review. A 'critical review', or 'critique', is a complete type of text (or genre), discussing one particular article or book in detail.  In some instances, you may be asked to write a critique of two or three articles (e.g. a comparative critical review). In contrast, a 'literature review', which also needs to be 'critical', is a part of a larger type of text, such as a chapter of your dissertation.

Most importantly: Read your article / book as many times as possible, as this will make the critical review much easier.

Read and Take Notes

To improve your reading confidence and efficiency, visit our pages on reading.

Further reading: Read Confidently

After you are familiar with the text, make notes on some of the following questions. Choose the questions which seem suitable:

• What kind of article is it (for example does it present data or does it present purely theoretical arguments)?
• What is the main area under discussion?
• What are the main findings?
• What are the stated limitations?
• Where does the author's data and evidence come from? Are they appropriate / sufficient?
• What are the main issues raised by the author?
• What questions are raised?
• How well are these questions addressed?
• What are the major points/interpretations made by the author in terms of the issues raised?
• Is the text balanced? Is it fair / biased?
• Does the author contradict herself?
• How does all this relate to other literature on this topic?
• How does all this relate to your own experience, ideas and views?
• What else has this author written? Do these build / complement this text?
• (Optional) Has anyone else reviewed this article? What did they say? Do I agree with them?

^ Back to top

Organising your writing

You first need to summarise the text that you have read. One reason to summarise the text is that the reader may not have read the text. In your summary, you will

• focus on points within the article that you think are interesting
• summarise the author(s) main ideas or argument
• explain how these ideas / argument have been constructed. (For example, is the author basing her arguments on data that they have collected? Are the main ideas / argument purely theoretical?)

In your summary you might answer the following questions:     Why is this topic important?     Where can this text be located? For example, does it address policy studies?     What other prominent authors also write about this?

Evaluation is the most important part in a critical review.

Use the literature to support your views. You may also use your knowledge of conducting research, and your own experience. Evaluation can be explicit or implicit.

Explicit evaluation

Explicit evaluation involves stating directly (explicitly) how you intend to evaluate the text. e.g. "I will review this article by focusing on the following questions. First, I will examine the extent to which the authors contribute to current thought on Second Language Acquisition (SLA) pedagogy. After that, I will analyse whether the authors' propositions are feasible within overseas SLA classrooms."

Implicit evaluation

Implicit evaluation is less direct. The following section on Linguistic Features of Writing a Critical Review contains language that evaluates the text. A difficult part of evaluation of a published text (and a professional author) is how to do this as a student. There is nothing wrong with making your position as a student explicit and incorporating it into your evaluation. Examples of how you might do this can be found in the section on Linguistic Features of Writing a Critical Review. You need to remember to locate and analyse the author's argument when you are writing your critical review. For example, you need to locate the authors' view of classroom pedagogy as presented in the book / article and not present a critique of views of classroom pedagogy in general.

Linguistic features of a critical review

The following examples come from published critical reviews. Some of them have been adapted for student use.

Example extracts from a critical review

Writing critically.

If you have been told your writing is not critical enough, it probably means that your writing treats the knowledge claims as if they are true, well supported, and applicable in the context you are writing about. This may not always be the case.

In these two examples, the extracts refer to the same section of text. In each example, the section that refers to a source has been highlighted in bold. The note below the example then explains how the writer has used the source material.    

There is a strong positive effect on students, both educationally and emotionally, when the instructors try to learn to say students' names without making pronunciation errors (Kiang, 2004).

Use of source material in example a: 

This is a simple paraphrase with no critical comment. It looks like the writer agrees with Kiang. (This is not a good example for critical writing, as the writer has not made any critical comment).        

Kiang (2004) gives various examples to support his claim that "the positive emotional and educational impact on students is clear" (p.210) when instructors try to pronounce students' names in the correct way. He quotes one student, Nguyet, as saying that he "felt surprised and happy" (p.211) when the tutor said his name clearly . The emotional effect claimed by Kiang is illustrated in quotes such as these, although the educational impact is supported more indirectly through the chapter. Overall, he provides more examples of students being negatively affected by incorrect pronunciation, and it is difficult to find examples within the text of a positive educational impact as such.

Use of source material in example b: 

The writer describes Kiang's (2004) claim and the examples which he uses to try to support it. The writer then comments that the examples do not seem balanced and may not be enough to support the claims fully. This is a better example of writing which expresses criticality.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed   Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

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.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

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.

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.

Implementing evidence into practice requires nurses to identify, critically appraise and synthesise research. This may require a comprehensive literature review: this article aims to outline the approaches and stages required and provides a working example of a published review.

Are there different approaches to undertaking a literature review?

What stages are required to undertake a literature review.

The rationale for the review should be established; consider why the review is important and relevant to patient care/safety or service delivery. For example, Noble et al 's 4 review sought to understand and make recommendations for practice and research in relation to dialysis refusal and withdrawal in patients with end-stage renal disease, an area of care previously poorly described. If appropriate, highlight relevant policies and theoretical perspectives that might guide the review. Once the key issues related to the topic, including the challenges encountered in clinical practice, have been identified formulate a clear question, and/or develop an aim and specific objectives. The type of review undertaken is influenced by the purpose of the review and resources available. However, the stages or methods used to undertake a review are similar across approaches and include:

Formulating clear inclusion and exclusion criteria, for example, patient groups, ages, conditions/treatments, sources of evidence/research designs;

Justifying data bases and years searched, and whether strategies including hand searching of journals, conference proceedings and research not indexed in data bases (grey literature) will be undertaken;

Developing search terms, the PICU (P: patient, problem or population; I: intervention; C: comparison; O: outcome) framework is a useful guide when developing search terms;

Developing search skills (eg, understanding Boolean Operators, in particular the use of AND/OR) and knowledge of how data bases index topics (eg, MeSH headings). Working with a librarian experienced in undertaking health searches is invaluable when developing a search.

Once studies are selected, the quality of the research/evidence requires evaluation. Using a quality appraisal tool, such as the Critical Appraisal Skills Programme (CASP) tools, 5 results in a structured approach to assessing the rigour of studies being reviewed. 3 Approaches to data synthesis for quantitative studies may include a meta-analysis (statistical analysis of data from multiple studies of similar designs that have addressed the same question), or findings can be reported descriptively. 6 Methods applicable for synthesising qualitative studies include meta-ethnography (themes and concepts from different studies are explored and brought together using approaches similar to qualitative data analysis methods), narrative summary, thematic analysis and content analysis. 7 Table 1 outlines the stages undertaken for a published review that summarised research about parents’ experiences of living with a child with a long-term condition. 8

An example of rapid evidence assessment review

In summary, the type of literature review depends on the review purpose. For the novice reviewer undertaking a review can be a daunting and complex process; by following the stages outlined and being systematic a robust review is achievable. The importance of literature reviews should not be underestimated—they help summarise and make sense of an increasingly vast body of research promoting best evidence-based practice.

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

How to Critique Literature

A literature critique, sometimes called a literary analysis or a literary critical analysis, is an examination of a piece of literature. The scope of a critique of literature may be to examine a single aspect of the work, or the work in its entirety, and involves breaking the literary piece apart into its separate components and evaluating how they fit together to accomplish the piece's purpose. Literary critiques are commonly executed by students, scholars, and literary critics, but anyone can learn how to critique literature!

Conducting a Basic Critique for Beginners

• For example, for a T-chart, list the names of the characters in one column and their actions in another as you read. After reading, you can add a column with why you think they did each action.

• This is similar to artwork. Instead of looking at a painting to figure out what the artist was communicating, just look at what is literally present in the painting. For example, what items are present in Van Gogh’s ‘’Starry Night’’? Don’t think about what he is trying to say in this painting; think about the stars, the swirling night sky, and the houses below.

• For example, ask yourself, why does the witch turn the prince into a beast in Beauty and the Beast? What does this action suggest about human nature?
• Also think about what lesson the reader can learn from the characters. What does the Beast teach us?

• The format for a thesis may look something like this: _______ is true because __________, ____________, and ___________. [3] X Research source The first blank is your opinion. For example, The Beast teaches us that we should be hospitable to everyone.
• The rest of the blanks tell why your opinion is true: The Beast teaches us that we should be hospitable to everyone because he learns from his mistake, becomes a compassionate person through his time as a beast, and regrets that he was ever rude to the witch.
• However, keep in mind that there are many different ways to form a thesis. What is most important if to make sure that your thesis includes a claim and a summary of the reasons for your claim. For example, you might phrase your thesis as “Because the Beast suffers for his actions, Beauty and the Beast argues that we should be hospitable to everyone and this theme carries through the story.”

• You can summarize these events, or use direct quotes from the book, but both need to have a page number. This prevents plagiarism.
• For example, you might use a quote that shows how the Beast is inhospitable as one of your first examples. Then, you might use other examples from the text to show the continuation of this theme.
• You do not have to use direct quotes all of the time. You can also paraphrase a passage by putting it into your own words, or summarize longer passages by describing the events in a less detailed way in your own words. No matter if you are quoting, paraphrasing, or summarizing, make sure that you include a page number for your evidence.

• Fill in the outline with topic sentences and events from the literature that support each topic sentence.

• Close the essay with a conclusion paragraph, where you summarize the essay in just a few sentences.

Applying Advanced Critical Techniques

• You should read with a pen and paper handy, as well as with a dictionary. Write down the main ideas in the margins and look up words as you go.
• Ask “how,” “why,” and “so what” questions to help you read critically.

• Evaluate elements of the work as you go, such as plot, themes, instances of character development, setting, symbols, conflicts, and point of view. [6] X Research source Think about how these elements interact to form the main theme.

• making a list,
• mapping out a web, and
• freewriting.
• For example, while reading Pride and Prejudice, you might feel that Mr. Darcy’s character needed more development than Jane Austen gave him, or you might prefer Jane’s character to Lizzy’s and feel that she would have made a better heroine (for example, Jane shares a name with the author, giving you grounds to explore the argument that Austen might have actually preferred her). Make a list, web, or freewrite out of ideas like these.

• The thesis should present your opinion in an arguable manner accompanied by a solid reason why your opinion is true.
• The formula for a basic thesis statement might look like this: _______ is true because of __________, ____________, and ___________. [8] X Research source

• You can also take advantage of an outline to form key sentences like the hook (first line of the intro paragraph), topic and transition sentences for each body paragraph, and your conclusion.

• Look at your notes and identify any patterns you see in the text that support your thesis statement, such as how no one is ever sure what Mr. Darcy is doing until after the fact, contributing to a lack of character development in Pride and Prejudice (if you were trying to prove the validity of an argument that Mr. Darcy is not developed enough, for example).
• You must include a page number or authorial attribution anytime that you: talk about a specific event; paraphrase a quote; paraphrase a passage; or use any direct quote. You usually insert a page number in parentheses after the sentence.

• You should also address any criticism that does not agree with your thesis, as refuting the counterargument also builds your credibility.

• If you created your outline on a word processor, then you can simply fill in the outline with additional information.
• You can also treat the outline as a roadmap. Consult it as you draft your paper to make sure that you are including all of the points and examples that you have identified.

• MLA is more common for literary-based essays, but you should ask your instructor if you are not sure.

• For example, after offering a quote, you might explain what the quote means or demonstrates as well as how it supports your thesis. Do not simply paraphrase or summarize the quotes after you offer them. Summary does not show critical thinking. Instead, try to explain the significance of each quote or example to your readers.
• Try to create quote sandwiches. A quote sandwich is simply how you position a quote in an essay. You should have a sentence introducing the quote and its author, then have the quote itself, followed by one or more sentences analyzing the quote right after it.
• Make sure you include a references/works cited list with all sources you quote from or paraphrase in the essay. This prevents plagiarism.

Evaluating Literature as You Read

• Questioning the title helps in determining the main theme and contributes to a more accurate critique.

• Setting—description of the surroundings.
• Plot—events of the text.
• Characters—the motivations and depth of each character, such as how much they change or don’t change as a result of the events. Characters can be people, objects, even ideas (especially in poetry).
• Conflict—the opposition that the main character encounters and its climax and resolution.
• Themes—what the narrator observes about human nature.
• Point of view—the way that a character thinks, whether it is curious, condescending, etc. Can also be the perspective the text is told, whether in first person, third person, etc.
• Tone—the way the text feels, whether sad, happy, angry, apathetic, etc.
• Symbols—objects, people, or places that repeat consistently throughout the story and seem to represent another abstract idea.

• You may want to write down your interpretation of the work at this point, as it is an excellent springboard into a thesis statement, if you end up needing to write a paper about this text.
• You can review outside sources such as peer reviewed articles and books to verify that your interpretation is accurate or needs work.

Community Q&A

• You should always consider how the writer's techniques contribute to the overall meaning of the text. Thanks Helpful 0 Not Helpful 0
• If you don't feel you have a good grasp of all the specific components after the first reading of a literary work, read it over again, with the components in mind, before you critique. Thanks Helpful 0 Not Helpful 0
• Be careful not to summarize the entire work when you critique literature. It is your job to evaluate the work's meaning, not to outline its plot. Thanks Helpful 0 Not Helpful 0

• Remember that the critical approaches mentioned above are complicated and take time to master. Unless you are already familiar with them or are completing an assignment using them, you may want to stay away from them for now. Thanks Helpful 1 Not Helpful 0

About This Article

To critique literature, start by carefully reading the text and then coming up with an opinion, like whether or not you think the author did a good job getting their main point across. Then, find evidence in the text to support your opinion, including things like quotes, events in the story, and actions the characters made. Once you have your argument and evidence support it, write your critique so that each paragraph addresses a different piece of evidence.

PEN America Cancels 2024 World Voices Festival Amid Further Fallout

Less than a week after canceling its 2024 Literary Awards ceremony  following months of  steadily mounting criticism  over the organization's response to the humanitarian crisis in Gaza, PEN America has also canceled what would have been the 20th edition of its World Voices Festival . Both cancellations were made in the wake of a series of withdrawals from awards consideration—along with award refusals, in the case of World Voices cofounder Esther Allen —and from participation in the festival by an unprecedented number of authors.

The organization's third tentpole spring event, the PEN America Literary Gala, is currently slated to proceed as planned on May 16. A representative of PEN America also confirmed that the PEN/E.O. Wilson Literary Science Writing Award, PEN/Jacqueline Bograd Weld Award for Biography, PEN/John Kenneth Galbraith Award for Nonfiction, PEN/Diamonstein-Spielvogel Award for the Art of the Essay, and PEN Open Book Award—which were to be announced on a different, as-yet-unannounced timeline  from the now-canceled awards ceremony—are also still proceeding as planned.

In recent weeks, PEN America's leadership has made some efforts to reconcile with its critics, including  committing to conduct a "review" of PEN’s work  "going back a decade." Moreoever, in the recent release announcing the cancellation of World Voices , PEN America’s chief officer of literary programming, Clarisse Rosaz Shariyf, pledged to host a town hall in the near future "to create a space to wrestle with the issues gripping the literary community and our own organization."

Stille, those efforts at reconciliation came even as PEN America continued to push back against those same critics. “We greatly respect those writers who have followed their consciences," Rosaz Shariyf said in a statement included in the release, "and stand with those who felt compelled to this decision by virtue of the pressures they faced.” 

In her own statement from the release, PEN America CEO Suzanne Nossel—who has been specifically mentioned in much of the criticism of the organization, especially of late —characterized recent critique as "a campaign that casts our struggle to reflect complexity, uphold our identity as a big tent organization, and show fealty to our principles as a moral abdication." She added: "The perspective that engaging with those who hold a different point of view constitutes an impermissible act of legitimization negates the very possibility of dialogue. It also betrays the essence of PEN’s charter and mission to dispel hatreds and engage writers and literature as a catalyst for empathy and a bridge toward common ground.” 

On Friday, PEN America also  shared on X (formerly Twitter) a thread paraphrasing an article in the Atlantic , written by Gal Beckerman, which characterized the recent criticism of the organization as being rooted in "a sense of righteousness that is impossible to contain within an organization built on the 'right to disagree'" and described PEN as "an organization that sees itself as above politics." In response to the thread, some writers on X pointed to the organization's stated commitment to human rights, advocacy for Ukraine amid Russia's invasion, and criticism of book banning in the U.S. as examples of its political involvements.

A  sympathetic op-ed in the  New York Times , written by former  New York Times Book Review  editor Pamela Paul, also prompted a response further indicating divisions in the literary world over how literary organizations should address issues related to the war in Gaza. After Paul called, in the piece, the website  Literary Hub  "the de facto clearinghouse for  pro-Palestinian  literary-world sentiment," Dan Sheehan, the editor-in-chief of  Lit Hub  vertical  Book Marks  and currently the site's lead writer on issues related to Israel and Palestine, joked on X that Lit Hub   might produce a tote bag  touting that characterization.

A number of authors and organizations that have criticized PEN America, meanwhile, have begun planning programming of their own. On May 7 at Judson Memorial Church in Manhattan, the Palestine Festival of Literature , Writers Against the War on Gaza , and  Amplify Palestine  will hold an event, " Freedom to Write for Palestine ," featuring some of the writers who have withdrawn from PEN America's now-canceled programming. The event will raise funds for the Palestinian nonprofit We Are Not Numbers .
