California State Archives
California's first legislature, meeting in 1849-50, charged the Secretary of State to receive "...all public records, registered maps, books, papers, rolls, documents and other writings...which appertain to or are in any way connected with the political history and past administration of the government of California..." The California State Archives, a division of the Office of the Secretary of State, continues to serve in the spirit of those early instructions, providing a repository for the state's permanent governmental records as well as other materials documenting California history.
