What is a Literature Review?

A literature review summarizes and analyzes available research on a specific topic.  By identifying and analyzing current research, the writer can identify themes, gaps and/or inconsistencies to demonstrate where future research is needed.  Results can be demonstrated either chronologically, thematically or conceptually (Cronin, Ryan, & Coughlan, 2008).
