Since 2004, GovTrack.us has housed information about the United States Congress, including 10 years of bills, voting records, and contact information for individual members of Congress. Visitors can also find out who represents them and search the database for committee assignments, legislative statistics, and the Congressional Record, which is the official record of daily proceedings in Congress. All the code that makes GovTrack run is open source, and all the information stored there is freely available to everyone.
