Literature Review Defined

Review the value and purposes of a literature review

BACKGROUND: Preparing a literature review is a way to familiarize yourself with the scholarly conversation going on in your research area. An effective literature review demonstrates to other scholars that you are very familiar with the scholarly conversation surrounding your research area and, therefore, that you fully comprehend how your own research fits into and contributes to the conversation. The information below will reinforce your understanding of literature reviews and their role in the scholarly conversation of researchers.

Literature Reviews: An Overview

What is a literature review?

A literature review describes key prior research that is related in a significant way to your intended research project. Typically, you will see a literature review as a section of an article, as an entire article of its own, or as a chapter of a dissertation.

Why do a literature review?

  • Reading the scholarly literature related to your research topic helps you:
    • Develop and deepen your understanding of your research area.
    • Develop a research project that is significant -- one that contributes to the field.
    • Develop a research project that does not accidently duplicate other research.
  • Writing the literature review demonstrates that you:
    • Have a thorough understanding of your area of study/research -- knowledge of significant earlier research and of current progress in the field.
    • Understand how your own research fits within the context of other research in your area of study  -- how it's based on prior work of others and how it builds on that prior work.

What does a literature review involve?

  • "... discovering, assessing, and assimilating others' research and then articulating your own ideas clearly and persuasively...." [1]
