ProQuest Legislative Insight
The Biddle Law Library recently acquired ProQuest Legislative Insight, a new database to assist with your legislative history research.
Like Penn's subscription to ProQuest Congressional (formerly LexisNexis Congressional), ProQuest Legislative Insight provides full-text PDF scans of many legislative documents. Unlike ProQuest Congressional, Legislative Insight organizes these documents by their affiliation with a particular piece of (passed) legislation.
For example, if you want to research Public Law 90-209, the National Park Foundation Act, you can search Legislative Insight for this particular law by name or citation. Since this Act is included in Legislative Insight's database, all documents affiliated with this act are available as full-text PDF scans. In ProQuest Congressional, whether or not the full text of the same documents is available depends on the year the document was created and ProQuest Congressional's subscription coverage.
Try turning to Legislative Insight first if you are researching a bill that was passed into law. While not all laws are included in this database, if Legislative Insight covers that bill you will have the full text of that particular legislative history available to you. If it is not available, make sure to still consult ProQuest Congressional or ask a reference librarian for assistance.
