What is a review of literature?

The format of a review of literature may vary from discipline to discipline and from assignment to assignment.

A review may be a self-contained unit — an end in itself — or a preface to and rationale for engaging in primary research. A review is a required part of grant and research proposals and often a chapter in theses and dissertations.

Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles.

What steps must you take in preparing to write a literature review?

There are a number of steps to undertake before you write the literature review. You need to:

  • formulate a problem in your field of study
  • familiarise yourself with a broad range of texts that deal with that problem
  • decide on the texts you wish to include in your review
  • decide on the most appropriate way to classify the texts
  • identify the key issues
  • critically analyse what you have read
  • identify important issues that are still unresolved
  • write a draft of the review
  • read and think about what you have written and then rewrite.

Writing the introduction

  • In the introduction, you should:

    Define or identify the general topic, issue, or area of concern, thus providing an appropriate context for reviewing the literature.

  • Point out overall trends in what has been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.
  • Establish the writer’s reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope).

Writing the body

  • In the body, you should:

    Group research studies and other types of literature (reviews, theoretical articles, case studies, etc.) according to common denominators such as qualitative versus quantitative approaches, conclusions of authors, specific purpose or objective, chronology, etc.

  • Summarize individual studies or articles with as much or as little detail as each merits according to its comparative importance in the literature, remembering that space (length) denotes significance.
  • Provide the reader with strong “umbrella” sentences at beginnings of paragraphs, “signposts” throughout, and brief “so what” summary sentences at intermediate points in the review to aid in understanding comparisons and analyses.

Writing the conclusion

  • In the conclusion, you should:

    Summarize major contributions of significant studies and articles to the body of knowledge under review, maintaining the focus established in the introduction.

  • Evaluate the current “state of the art” for the body of knowledge reviewed, pointing out major methodological flaws or gaps in research, inconsistencies in theory and findings, and areas or issues pertinent to future study.
  • Conclude by providing some insight into the relationship between the central topic of the literature review and a larger area of study such as a discipline, a scientific endeavor, or a profession.
