Literature Reviews: What They Are and Why They're Important

What They Are
  • A summary of the relevant literature of a subject.
  • Depending on your subject and your field, can be chronologically broad or narrow.
    • Sciences tend to emphasize currency.
  • BUT in whatever field, if there is some fundamental text that defined the field or topic of study, that must be included no matter how old it is.
  • Lit reviews range from a few paragraphs to a few pages.
    • Or can be extended into a paper solely reviewing recent literature.
  • Annotated bibliographies are literature reviews but not in essay form.

 

Why They're Important
  • “Analyzing the past to prepare for the future.”*
  • To discover the patterns that emerge within the large body of work devoted to one issue.
  • How do the studies speak to each other?  Does one find one thing and another find something contradictory?  Does one ask a question that another follows up?
  • To establish an evidentiary basis of common thought and current questions about a subject at the given moment.

How to Write a Literature Review

Analyze!  Evaluate!  Synthesize!

Froese, A. D., Gantz, B. S., & Henry, A. L. (1998). Teaching students to write literature reviews: A meta-analytic model. Teaching of Psychology 25, pp. 102-105.

Analyze

  • Keep an eye out for:
    • Pertinent info – who/what/where/when/why
    • Methods – the ever important how
    • Page numbers if you quote something (for easy transfer into your paper!)
    • Numbers (not just “increase/decrease” but “up 50%” or “down 24%”)
  • Why was each article written?

Evaluate

  • Do you observe any patterns between articles? Is there a common thread in the research done in this field?
  • Conversely, do you see any gaps in research? This is a good way to figure out what you can study yourself.
  • How does each article compare to the others?

Synthesize

  • Use your spreadsheet (or whatever means by which you keep your articles organized) to sort the articles by pattern or theme
  • Write what you found into a linear narrative, tying all the studies together by their subject matter and findings, grouping certain studies by pattern/theme
  • Quote if necessary but sparingly
  • Keep it succinct -- it’s a lot of material but it’s not the bulk of your paper (unless it’s your whole paper!)

One Way To Track What You Read
