Finding aids are guides that let users navigate collections by describing how archival collections have been arranged, what kinds of materials they contain, and the even history of the collection/creator. The Online Archive of California aggregates the finding aids from archives, libraries, museums, historical societies, and other cultural institutions across California to make resources and collections easy to find.

Explore the Pioneer Room’s finding aids on the Online Archive of California (constantly updated).
