What is a literature review?

Before understanding how to write a literature review, one must learn what is a literature review. A literature review is a summary of published work on a subject of study. This may be a section of a bigger paper or article or maybe the focus of a whole paper. Literature reviews show that you have tested the breadth of knowledge and can justify your thesis or research questions. They also are valuable tools for different researchers who need to find a summary of that subject of knowledge. Unlike an annotated bibliography, which is a listing of sources with short descriptions, a literature review synthesizes sources right into a summary that has a thesis or statement of the purpose stated or implied at its core.

In other words, while writing a research paper on a particular topic, you’ll often need to include an overview of any prior research that has been conducted on that topic. This is the answer to those asking what is a literature review. For example, in case your research paper is describing an experiment on fear conditioning, then you’ll possibly need to offer an overview of previous research on fear conditioning. That overview is usually referred to as a literature review. Now before getting to know how to write a literature review, we’ll discuss the fundamentals of literature review.

The fundamental components of a literature review include:

  • A summary of the publication’s major points;
  • A discussion of gaps in research;

 

How to Write a Literature Review

The following steps will answer the question – How to write a literature review. So let’s get started!

 

1. Identify and define the subject that you’ll be reviewing.

The subject matter, which is generally a research question (or problem) of a few kinds, needs to be identified and described as clearly as possible.

At this level, it can be useful to write down a description of the research question, area, or subject matter that you’ll be reviewing, in addition to identifying any keywords that you’ll be using to look for relevant research. This is step one on how to write a literature review.

Read through titles and abstracts, choose and obtain articles (that is, download, copy, or print them out), and save your searches as needed. This is the second step on how to write a literature review.

However, the degree of emphasis that is given to individual research may also vary (more or less detail can be warranted depending on how important or unique a given study was).

It is one of the most essential steps on how to write a literature review. After you’ve got written the first draft, you must read it cautiously and then edit and revise as needed. It is possible that you might have to repeat this process more than once. It can be useful to have another person read through your draft(s) and offer feedback.

After the literature review is complete, you must incorporate it into your research paper (in case you are writing the review as one component of a bigger paper). Depending on the stage at which your paper is, this will involve merging your literature review into a partially complete Introduction phase, writing the rest of the paper across the literature review, or different processes.
