The following are possible sources for your literature review:

Journals: Scholarly, peer-reviewed articles are written by experts in the field with other experts in mind as an audience. These articles often report on primary research within a very specific niche of a scholarly discipline.

Dissertations/Theses:

Conference Proceedings:

Books: Books generally are not peer-reviewed, but are often written by experts such as professors or scientists. Many of the books in USM libraries have been chosen by librarians specifically because they are based on peer-reviewed or otherwise authoritative sources. Though there are books that contain essays on very specific topics, books are generally a good place to get a detailed overview of a subject.

Government Publications: Although government publications are not peer-reviewed in the traditional academic sense, they generally undergo rigorous internal review. Government sources can be excellent sources of primary data. In some subject areas, government publications may be the only sources of information available.

Internet: Because there is no review process for much of the information that you may discover while using a search engine, it is extremely important to evaluate Web sites with a critical eye in order to determine whether the source is authoritative, unbiased, and current. However, there are some worthwhile sources on the Web.
