Legislative History Research Guide

This guide collects major sources for conducting legislative history research, including committee reports, hearings, bills, debates and more.


House and Senate committees hear testimony on proposed legislation in order to determine the need for new legislation in a particular area and to hear the views of various persons or organizations interested in the legislation. Hearings can provide a wealth of information for background research into the issue Congress is addressing. Hearings are held for almost all substantive legislation and transcripts of most hearings (including exhibits provided by those testifying) are published. For interpreting enacted legislation, hearings may be less useful than other legislative documents because they focus on the views of the parties testifying rather than the views of the committee or Congress.

The Law Library has selected individual hearing transcripts in both paper and microform. Search for them in our catalog by the title of the hearing, name of the committee, or the subject of the investigation. Hearing transcripts are also available electronically; see the list below.

Databases for Hearings

For very recent hearings you may find that transcripts are difficult to find.  First, note that you may be able to obtain hearing materials from the committee website itself.  The Federal News Service (available via Westlaw) also transcribes selected hearings and uploads them daily. A final source to check for recent hearing transcriptions is CQ Transcriptions on Nexis Uni (see note below).

You may also be able to find video recordings of hearings at C-SPAN.org (sometimes these have search-able closed captioning, though be aware that this captioning may contain spelling errors).
