Sometimes, you will be able to find a book or article that either brings together many of the relevant documents pertaining to a particular act, or at least provides citations to, and/or excerpts from, these documents. Useful tools for finding if such a compilation exists for the act you are researching include the library catalog, legal periodical indexes, and full text law review databases.
For guidance on using these tools, consult the USC Law Library guides Finding Library Materials through Online Catalogs and How to Find Law Journal Articles. When you use these research tools to find California legislative history, make sure you include "California" as one of your search terms. You may also find it helpful to include search terms such as "legislative," "history," and/or "intent" along with your topical keywords.
