A literary review's length varies according on its objective and readership. The review is often a complete chapter (at least 20 pages) in a thesis or dissertation, however it may simply be a few pages in an assignment. A literature review can be organized and structured in a variety of ways. The most common structures are thematic analysis, critical review, summary review.
Thematic analysis consists of grouping topics that appear in the text together related to their topic category. For example, if one were writing on "American history," thematic analysis would involve grouping events into categories such as "Civil War" and "Modern American History." These groups of topics and events would then be analyzed using theory from social psychology or other disciplines to explain what kinds of factors cause people to think and act as they do. The result is a description of how historical events and trends affect modern Americans which can include explanations about why some ideas have been popular at certain times and not others.
In critical reviews, the goal is to evaluate the work of other scholars by looking at both its strengths and weaknesses. Critical reviews usually begin with a discussion of the history of the field and how it has changed over time before discussing more recent works that move beyond the mere listing of authors and titles. For example, one might discuss earlier work by Emerson and Thoreau on nature essayism and later studies by psychologists who want to know whether this type of writing is effective for teaching children language skills.
In the absence of particular directions, a common rule of thumb is that the length of your literature review should be commensurate to the length of your overall report. If your work is 15 pages lengthy, 2-3 pages for the literature review may adequate. However, if you have 20 pages of data to analyze, it might be appropriate to devote more space to the review.
The purpose of the literature review is twofold: first, to provide a comprehensive summary of studies on the topic under discussion; second, to use this evidence to build a case for your own analysis or interpretation of the facts.
Thus, the length of your literature review should be sufficient to fulfill these purposes. Generally, a review of at least 50 pages is considered sufficient depth. Studies with more extensive methodological approaches or broader analyses than others in the pool will usually require more space.
When writing your review, keep in mind that it will be read by humans, not robots. Thus, although multiple-page reports are now acceptable in most academic settings, reviewers will likely skip over long documents unless its contents are particularly interesting or relevant to their project. So while a 60-page report may be acceptable within the context of a single study, page limits will likely prevent it from being included in a collection of articles published in a journal.
A literature review is typically included as a portion or component of a dissertation, research project, or long article. It can, however, be assigned and graded as a stand-alone piece of work. The literature review examines the existing research on your topic to determine what has already been done and what might be helpful as you begin your own research.
Literature reviews often summarize a large body of material in a concise and readable format. They are an important tool for researchers to use when they first start out with a topic because they allow them to see what other people have found interesting about it. By reading other studies, we are able to understand their strengths and weaknesses, which helps us judge how well our work will do when we try to reproduce these results.
In addition to summarizing previous research, literature reviews can also point out gaps in knowledge where more research is needed. For example, while there have been many studies on how personality traits affect employment outcomes, no one has yet examined whether different jobs require different combinations of traits in order to be performed effectively. A literature review that identifies such gaps can help researchers decide what topics should be the focus of future studies.
Finally, literature reviews can help researchers decide what questions need to be asked in their own studies by pointing out areas where additional research would be useful.
If you are writing a literature review as a stand-alone document, A stand-alone literature review with 10 pages of material (the body of the article) should, for example, look at at least 30 sources. These are not, by any means, hard and fast rules. But they do provide some guidance on how much research to include in your paper.
In addition to providing information about your topic, the literature review can also help organize and structure your essay by grouping related studies together by topic. The more sources you can find that discuss a particular topic within your essay, the better because it will give your readers additional information to consider while reading your paper.
The goal of the literature review is not only to identify relevant studies but also to describe these studies in enough detail for others to evaluate whether they are worth including in their own work. Therefore, it is important that you spend time reviewing each study you select so that you understand what the authors found interesting or significant about their subjects. This will help ensure that you include accurate information in your paper and avoid missing important details that other researchers may want to know about later.
As you can see, the literature review is a very important component in any academic essay because it provides information about the topic at hand as well as helps organize and structure the paper. Without adequate evidence from relevant studies, an argument written in an unsupported manner will likely be rejected by reviewers.
