A Literature Review establishes the connection between your proposed research and existing research; it surveys for the reader the scope of existing research, and then explains how the proposed dissertation research expands upon or adds new information to the knowledge base. It reviews previous studies, analyzes gaps, and outlines a research agenda. " A literature review therefore helps us to appreciate something of the sequence and growth of knowledge. As we survey the previous research on a subject, we may be able to identify areas which have not yet been investigated. These might suggest topics for future research projects, and also might suggest a particular focus or train of thought for our present dissertation" (Oliver, Paul, 2012).
A literature review is not simply a survey of one author or researcher after another; there needs to be a selection process with some criteria in place to determine which articles, dissertations, thesis, etc., to include and exclude in the review.
It should NOT strictly consist of summaries
It should reflect your ability to analyze and discuss others' research
It will probably need to be organized using sections and subheadings
