What is a Literature Review?

A literature review ought to be a clear, concise synthesis of relevant information. A literature review should introduce the study it precedes and show how that study fits into topically related studies that already exist. Structurally, a literature review ought to be something like a funnel: start by addressing the topic broadly and gradually narrow as the review progresses. (from Literature Reviews by CU Writing Center)

Reference to prior literature is a defining feature of academic and research writing. Why review the literature?

  • To help you understand a research topic
  • To establish the importance of a topic
  • To help develop your own ideas
  • To make sure you are not simply replicating research that others have already successfully completed
  • To demonstrate knowledge and show how your current work is situated within, builds on, or departs from earlier publications (from Literature Review Basics from University of La Verne)

Literature Review Writing Tips

Synthesize your findings. Your findings are your evaluation of the literature reviewed: what you consider the strengths and weakness of the studies reviewed; the comparison you did between studies; research trends and gaps in the research that you found while researching your topic, etc...

Across the articles that you read, pay attention to:

  • Key points, objectives, & conclusions
  • Common/contested findings
  • Important trends
  • Influential theories

Literature Review Example

Annotation is Key!

Why Annotate? 

Answer: To save yourself time and frustration later in writing the literature review! Truly, this is your opportunity to quickly evaluate a source for key ideas, important data, and helpful quotes which can easily be recalled for use in writing the Literature Review. Why struggle to remember where you saw a key piece of information, when a quick, organized note and highlight could easily save you the trouble. Doing this work at the beginning of exploring sources will save you some real headaches later. Remember, an annotation is a critical evaluation (the notes) you make of a source and its key elements, conclusions and objectives.
