Literature Reviews

What is the purpose of a literature review?

  • First, it should analyze critically a body of research. This does not mean to simply summarize what other studies do, but rather to identify and discuss strengths and weaknesses.
  • Second, the literature review should put your own study in the context of others. Are there other studies on the same topic?
  • Third, your review should highlight your study’s contribution. How does your study differ from others?
  • Fourth, the literature review establishes your scholarly credentials by showingyou have done your homework.

What should a literature review contain?

  • Begin with comments about the body of research as a whole.
  • Generally speaking, a review should progress from the broad to the particular.
  • Do the studies focus on methodological issues, or data issues, or some other issue?
  • Have the studies been mostly empirical, or theoretical, or both?
  • Have they focused on a similar set of questions?
  • Do they mostly date from a certain period?
  • Organize your review according to a theme (data, methodology, results, etc).
  • Begin paragraphs with a sentence that puts in explicit context what follows (In other words, use topic sentences).
  • Explain the merits and the shortcomings of the existing studies. Be explicit about this.
  • Explain how your study will make a contribution.

What is a Literature Review?

Purpose of a Literature Review: Gives readers an overview of sources explored while researching a particular topic. Demonstrates how research fits into the larger field of study.

Where Can Literature Reviews be Found?: Literature reviews can be incorporated into a research paper or empirical journal article or published alone.

Synthesis: A literature review should evaluate and combine to create a new, original work. It does not mean simply describing or summarizing.

Assessment of the Sources: Assessing sources necessitates comparison and the use of language such as “however, but, although, in addition, in contrast.”

Comparison: Comparisons are essential; descriptions alone are not illuminating.

Evaluation: Strengths and weaknesses of the studies should be asserted and the study should explain what remains to be done.

  • Assertions must be supported with evidence
  • Many writers find it easy to describe, but balk at evaluating the work of established scientists
  • Evaluation requires more thought and entails more risk than description, but without it, the paper is little more than a report.

A Literature Review is NOT:

  • An annotated bibliography or list of references with a paragraph summary for each source
  • A string of abstracts on a given topic

Characteristics of Literature Reviews:

  • Narrow topic
  • Incorporation of only scholarly material
  • Analysis of methodology, statistics, results, theoretical framework, or the author’s purpose, etc.
  • Acknowledgement of controversies when they appear in the article
  • May summarize strengths and weaknesses of how the author conducted the study
  • Few (or no) quotations; use summary instead
  • Persuasive, not just “informative”
  • Thesis is based on a research question and contains student’s claim and all main headings in the paper
