What's a tertiary source?

Tertiary sources are excellent starting points!  They consist of information synthesized from primary and secondary sources.  Examples include:

  • Almanacs
  • Chronologies
  • Dictionaries and Encyclopedias
  • Directories
  • Fact books
  • Guidebooks
  • Indexes, abstracts, bibliographies used to locate primary and secondary sources
  • Manuals
  • Textbooks

These resources give you succinct overviews of your topic, explain scholarly arguments, point out interesting questions, and refer you to especially key sources.
