You can use "tertiary" reference sources (e.g., encyclopedias, biographies, almanacs, etc.) to learn about possible topics, and to gather helpful background information on these topics. These sources provide broad overviews, but also often contain bibliographies that point to more relevant sources. The following reference websites allow for keyword searching and subject browsing.

• Oxford Digital Reference Shelf

  Two million digitized entries from Oxford dictionaries, companions, and encyclopedias in 25 different subject areas.

• Credo Reference

  Links to various reference books including dictionaries and encyclopedias from every major subject including art, science, history, music, foreign language, politics and literature.

• Britannica Online

  Online version of a broad, general-knowledge encyclopedia.

• Gale Virtual Reference Library

Specialized reference sources particular to a discipline or area of study can be especially good starting points. The following are available online and are keyword searchable and browsable by topic.
