There are several different types of literature available and you may draw on all of them. The ones you will refer to in your literature review generally fall into two main areas.

A source may serve more than one function. For instance, a journal article could include background information, exhibits, argument and method. However, some sources are focused on a single function. For example, an encyclopedia entry on “Alzheimer's disease” is likely to only serve as background information.
