Legislative History Resources

Compiling a California Legislative History is a complex process. A legislative history consists of the documents produced during the bill proposal, passage and enactment stages. Multiple resources must be located and consulted which may prove difficult in that many legislative documents are not consistently published. Additionally, legislative information prior to the 1970's was not well preserved so it may prove especially difficult to locate earlier legislative resources.

Document Description
Code By reviewing the code the researcher can also locate the Bill number and the Chapter number which are needed to track textual changes. The parenthetical history section is usually located at the top of each chapter, some chapter sections also contain "Historical Derivations" with historical content pertinent to that section of the chapter. The researcher should look at the beginning of the chapter as well as specific sections to locate historical content.
Assembly File Analyses Published by a now closed Assembly Office of Research, includes the bill analysis, digest, amendments and the fiscal effect of the bill. The assembly files were produced in microform from around 1975 to 2002.
Committee Reports Though infrequently published, committee reports from 1946 through 1970 may be found in the Senate Journal. The Assembly Journal may contain committee reports dated from 1956 through 1970. Published reports are also listed in the California State Publications, a monthly listing of official publications received by the California State Library from California governmental agencies.
Committee Analyses Legislative committee analysis of bills. These documents are generally not published in print, but may be found included with the bill information from a Bill Search with the California Legislative Information (from 1999 - ).
