U.S. Government Information & Congressional Publications

About Hearings & Testimonies

A committee holds hearings to determine facts, to sample opinion, and to carry out its oversight functions. A hearing on a bill will usually reprint the bill. Hearings are not held for all legislation; not all hearings are published. The published hearing includes the testimony of witnesses, transcripts of question and answer sessions, and copies of any exhibits and materials introduced.

Hearings are not always about a bill. They may be exploratory or investigative.

The testimony of the hearing (available through ProQuest Congressional 1988 -) is the transcript or prepared text of the witnesses and the transcript of the question and answer session.  Note: testimonies are available much more quickly than the published hearing.

Identifying & Locating Hearings

If you have a title, be sure to search DELCAT. If you wish to search by keywords, your searching may be easier in some of the full text databases, such as ProQuest Congressional Publications.
