The Online Archive of California (OAC) provides free public access to descriptions of primary resource collections maintained by more than 150 contributing institutions, including the California Academy of Sciences. The OAC lists basic records for much of the Academy's Manuscript Collections, as well as fuller finding aids for selected holdings. New finding aids are added to the OAC on an ongoing basis. The Academy Library also maintains a more complete list of our manuscript holdings.
