A bibliography is list of bibliographic citations, (also called Works Cited, Literature Cited, Reference List) at the end of a journal article or book that lists the sources used by an author.
Bibliographies can also be research tools that bring together in one location (either print or electronic) citations from articles, books, book chapters, disserations, conference proceedings, primary matierials, and other academic sources about a specific topic. That topic might be broad, such as "Medieval history" or very narrow, such as "Red-haired women mentioned in courtly litearature."
Bibliographies can be useful for discovering additional sources for your research. Since they include many different types of sources, it is important to be able to identify the type of source from the citation, in order to locate it.
Do a keyword search in the library catalog for your topic and bibliograph* (which will look for bibliography, bibliographic, or bibliographies). You can limit your search to Doe Reference, but many bibliographies are located in the regular stacks of the libraries across campus.
