The bill "history" is actually just a chronology of actions taken on the bill.
Critical information from the "history" includes: (1) bill authors and sponsors; (2) dates of amendments; and (3) reviewing committees. Information about committees helps you find published or unpublished reports or hearings. Knowing authors' and sponsors' names lets you request from them any unpublished information on file.
Bill histories are listed by bill number and are printed in each session's Senate (or Assembly) Final History (or, before 1964, in the Final Calendar of Legislative Business).

This is the single most important step in researching California legislative history and intent!
Often the only clues to intent are in (1) the occasional explicit statement of intent, (2) whatever you can infer from the language of the bill — the various amendments, additions, and deletions made to the bill as it went through the legislative process, or (3) theLegislative Counsel's Digest, which precedes the text of the bill.
The Legislative Counsel's Digest accompanies each version of every bill and compares current law to the proposed bill. It may also be found in the Summary Digest.
