The schedules are the records of who lived where when the decennial censuses were taken and are highly valued by genealogists. There is a 72 year restriction on the release of these records. To date, the 1930 schedules are available on microfilm. A fire destroyed almost all of the 1890 records. The CSUS Library has purchased microfilm for northern California cities and counties. They are available in the Gov Docs microfiche cabinets on 2 North under the call number C 3.23. The contents note indicates which counties are on which reel of microfilm. This film needs to be viewed in the Library Media Center (1st floor).
