The California Ballot Measures Database is a comprehensive, searchable source of information on California ballot propositions and initiatives from 1911 to the present. It includes the full text of individual ballot propositions, accompanying information contained in the ballot pamphlets, related legal and legislative history, and pdfs of the full ballot pamphlets. For ballot initiatives, it contains the full text of the individual initiatives, accompanying material relating to their filing & qualification, related legal and legislative history, and pdfs of related official documents.
The California Ballot Measures Database was made possible in part by a grant from the LSTA program and is a complimentary service provided by UC Law SF College of the Law Library. All of these materials are for education and preservation purposes under fair use. The Library is able to accommodate reasonable requests for metadata in the Ballot Measures database providing that there is appropriate attribution. We have no preferred citation style or format, but ask that you include the name of the collection and UC Law SF Library in your citation. In addition, there may be a fee for copying or other services.
