Getting Started With Your Research
The Center for Legislative Archives holds records from both the U.S. House of Representatives (Record Group 233) and the U.S. Senate (Record Group 46), as well as the records of legislative branch agencies and commissions. Our holdings are reflective of all aspects of the legislative process, so before you begin legislative research, it’s important to understand the structure of the U.S. Congress.
Legislative sessions of the House and Senate are grouped together in a numbered Congress that spans a two-year period, beginning with the first Congress (1789 - 1791). Accordingly, legislative records are arranged first by chamber and then by Congress number. It’s important to know which Congress(es) your research covers. For your reference, the U.S. Senate website maintains a list of congressional session dates.
If you do not know if your topic intersects with the U.S. Congress in general, or if you do not know the specific year, or in what capacity it would appear in our holdings, we recommend starting with a search of the published congressional records—particularly committee reports and committee hearings, as well the Congressional Record.
Congress publishes a huge volume of information on the work that it does. The published record can serve as a guide to what may be available in the unpublished records in our holdings. Or you may even find what you're looking for in the published record.

While this is not a comprehensive list of resources, it is a good starting point for legislative research—particularly if you're just getting started. After spending time with these resources, you will have a better idea of how your topic intersects with the U.S. Congress. Email us at legislative.archives@nara.gov with any questions.
