The California State Archives, located in Sacramento, has a variety of legislative materials. It is the repository for legislative committee records. State law does not require individual legislators to deposit their records in the State Archives, but more than 300 have chosen to do so. Many of these documents are unpublished and may only be obtained at the archives.
For pre-1993 legislation (pre-Internet), the State Archives may be the only place to find committee analyses.
