The majority of materials in Special Collections & Archives are archival. Archival materials are described as collections, and consist of unpublished records created by a person, family, or organization in the conduct of their affairs, kept because of their ongoing value. Each collection has a Finding Aid, which is similar to the Table of Contents in a book. Finding Aids in Special Collections & Archives are searchable via our institution page on the Online Archive of California, which is linked directly beneath the OneSearch box on the library's homepage.
