No topic can be adequately researched without using periodicals.

Periodicals are journals, magazines, and newspapers. They contain articles published "periodically" (in intervals), making them very good current sources of information.

Some examples of periodicals:

	Journal of Politics, a scholarly journal
	People Weekly, a magazine
	New York Times, a newspaper

Periodicals are available in the following formats:

	print (paper)
	microfilm
	microfiche
	electronic (online)
