From the library at the North Carolina State University at Raleigh:
Congressional Committees Meetings Index
http://www.lib.ncsu.edu/congbibs/
The U.S. Congressional Bibliographies enumerate and describe meetings held by Congressional committees since 1985, those for which printed transcripts are issued, and those that remain unprinted.
Its sources are the Congressional Record's "Daily Digest" and bibliographic information supplied by the U.S. Senate Library. Its primary goal is to be an authoritative, exhaustive reference source of meetings held and documents released by House and Senate committees.
