California Legislative History

This guide provides an overview of California legislative history materials available at Rains Library, as well as a how-to guide to perform your own legislative history.

Locating Bill Analyses

Bill analyses are written by staff working for the legislature. Analyses explain how the bill changes existing law, identify who supports and opposes the bill, and summarize arguments for and against the bill. Although the analyses are written by legislative staff, not the legislators themselves, they provide insight into the issues legislators considered when voting for a bill. They also often provide extended quotes from the bill's author, explaining the author's purpose for the bill.
