Legislative materials are also available in larger libraries throughout the state.
The Legislative Library has information sources to help in identifying a specific bill number from a previous session, based on such criteria as subject matter, sponsor, or requesting agency. Introduced bill information for a specific session can often be found by using the Subject Index found in the History and Final Status publication. The Library also has historical reports that are helpful in identifying legislation that was requested, whether or not it was introduced. Unique materials held at the Legislative Library include archival copies of the drafting record books from 1973 forward, interim committee work papers for the past 3 bienniums, and extra copies of some Legislative Services interim study final reports for distribution. Original, signed bills and session laws are held by the Secretary of State's Office .
