What is a literature review?

A literature review is a survey and critical analysis of what has been written on a particular topic, theory, question or method.

"In writing the literature review, the purpose is to explore what knowledge and ideas have been established on a topic, what approaches and viewpoints have been adopted, and what are their strengths and weaknesses."

Types of literature reviews

The type of literature review you do will depend on a variety of factors:

  • Your discipline
  • The purpose - undergraduate assessment, PHD thesis, journal article?
  • Your lecturer or supervisor's requirements
Note: Always follow the guidelines outlined by your lecturer or supervisor; or consult the instructions for authors (for journal articles), when conducting your literature review.

Types of literature reviews

  • Narrative or traditional literature review -
    • is an overview of the significant literature on a topic
    • typically includes a critical analysis of each work included
    • demonstrates the reviewers knowledge of the topic
  • Annotated bibliography - 
    • is a list of citations of research sources (books, journal articles, websites etc) on a topic
    • includes a brief summary and analysis or evaluation of each citation = the annotation
  • Systematic literature review  -
    • a critical assessment of all research studies on a particular research question
    • has specific criteria for collecting and evaluating the literature
    • includes a synthesis of the findings of the included studies
  • Systematic quantitative literature review -
    • This method developed by Griffith University's School of Environment bridges the gap between traditional narrative review methods and meta-analyses to enable student's to produce results that are reliable, quantifiable and reproducible.

What is the difference between a literature review and a systematic review?

The requirements of narrative literature reviews are usually quite different than systematic reviews. However, you may be required to adopt some of the characteristics of a systematic approach when doing your literature review. Check the guidelines or criteria that have been set by your supervisor so you know what is expected of you.
