A Literature Review is a piece of discursive prose. It should not be a sequence of summaries and evaluations of each article. Think of the literature review more as a narrative, in your own voice. Sources must be integrated to the overall story you are telling. Consider the following ways to organize your review:
♦ By themes, issues.
♦ By varying perspectives on a topic of controversy.
♦ Chronologically, limiting to a defined time period.
