Literature Reviews: what undergraduate students need to know
The narrower the topic the easier it will be to limit the number of sources you need to read.
A Literature Review is a select list of available resources covering the topic in question accompanied by a short description AND a critical comparative evaluation/analysis of the works included http://www.library.arizona.edu/help/tutorials/litreviews/whatis.html
Major points to consider
Questions to ask
Literature: a collection of materials on your topic. You must understand the difference between primary, secondary, and tertiary literature. (Does not mean “literature” in the sense of “language and literature,” e.g., To Kill a Mockingbird, Jane Eyre.)
Primary—peer reviewed, scholarly, original
Review: to look again at what has been written.
(Does not mean giving your personal opinion or whether or not you liked the sources.)
Research: to search again.
What is the purpose of a Literature Review? Why do people develop them?
How is a Literature Review organized? How do I do a Literature Review?
Do not use materials from the Internet unless it is a professional, peer reviewed scientific journal. Ask a librarian or your professor
to be sure if items from the Internet are valid and meet scholarly criteria if you have questions or doubts.
