Chap 3: the lit review

What is a literature review? 

A literature review is :-

1. A survey of everything that has been written about a particular topic, theory, or research question. 

2. It may provide the background for larger work, or 

3. It may stand on its own. Much more than a simple list of sources, an effective literature review analyzes and synthesizes information about key themes or issues.
