Bibliographies:

journal cover   A bibliography is a list of information sources. There is almost an infinite variety of types of bibliographies: they can be current or retrospective, format specific (Audiovisuals for Women ) or inclusive, universal in scope or subject specific, enumerative (just a list—no frills) or annotated (include descriptive or evaluative information); they can be as short as one page or as long as a multi-volume book. Finding a bibliography on your topic can be enormously useful because someone else has done the work of identifying relevant sources.
