The collection consists of correspondence, clippings, legislative and legal documents, pamphlets, publicity flyers, photographs, financial records, meeting minutes, event posters, petition forms, memoranda, speakers' manuals, volunteer forms, and other material documenting the campaign to defeat California Proposition 6, also known as the Briggs Initiative, in 1978. The bulk of the collection documents the activities of the three groups organized to oppose the initiative: the No on the Briggs Initiative Committee (NOBIC) and the Committe Against the Briggs Initiative/Los Angeles (CABI/LA), both based in Los Angeles, and the Bay Area Committee Against the Briggs Initiative (BACABI) based in San Francisco. The collection also includes legal papers and other material documenting the activists' lawsuits filed against the Briggs Initiative in an attempt to remove it from the November 1978 ballot.
