About the CA State Archives

The California State Archives collects, catalogs, preserves, and provides access to the historic records of state government and some local governments. The Archives collection is primarily composed of records from California state agencies, the governor's office, the state legislature, and the State Supreme Court and Courts of Appeal. The records are organized under the name of the agency or office that transferred the records to the Archives. The collections also include some private papers that have been donated to the Archives. As of January 2009, the collection consists of millions of paper documents, maps, photographs, three–dimensional artifacts, and records in other formats such as audiotape and videotape.
