Question: What value has a reference book? Why, for example, consult a scholarly history encyclopedia?
Answer: Encyclopedias are two steps removed from the primary source evidence, that is from the letters, diaries, oral histories, and other first-hand accounts of history. Encyclopedias are instead based on secondary sources. For that reason, encyclopedias and other reference works belong to a class of information sometimes called tertiary sources by librarians.
In short, the reference works listed here are a great way to begin any history-related research project!
