Finding Legislative History

There are two primary sources for finding legislative histories: and ProQuest Congressional/ProQuest Legislative Insight. is a free website; ProQuest Congressional is a paid database accessed through the Library's website. provides access to full-text published documents produced during the legislative process.  You can search by citation, or by keyword, public law name, etc.

ProQuest Congressional provides the same types of materials as, but the database allows for a more robust search. ProQuest Legislative Insight (a database within ProQuest Congressional) gives you the ability to do a keyword search through all documents related to a public law/statute.
