The two types of databases that you will be using are: library catalog and article indexes.

Library catalogs	organize all of the materials a library purchases. These include records for books, magazines, journals, newspapers, videos, sound recordings, images, etc.
	The MTSU library catalog is called InfoSearch
Article indexes	are used to identify articles on a topic.
	Some article indexes such as General OneFile are general or multidisciplinary.
	Many indexes specialize in a particular subject area, such as biology, education, or business.
