The Law Library of Congress in a collaborative pilot project with Google is undertaking the digitizing of the Library's entire collection of printed hearings (constituting approximately 75,000 volumes). As of 2010 three collections (on the decennial Census, FOIA and Immigration) have been selectively compiled as a test. It is hoped the project will eventually provide full-text access of the entire collection which will be posted online by Google and the Library. ProQuest offers subscriptions to a database of digitized hearings (published and unpublished) covering 1824 to the present.
