The Legislative Explorer tracks the progress of every bill and resolution introduced in Congress since 1973 — 250,000 in all. It notes each time a bill or resolution advances from one stage of the process to the next, in or out of committee or moves to the floor for consideration, totaling about 750,000 such movements.
Users can drill down through the graphically presented data in lots of ways, including by type of legislation, sponsors, party or chamber of origin. The tool also has filters allowing users to sort results many ways, including by gender of sponsoring legislator, committee affiliation and — perhaps most helpful of all — whether the legislation is considered major or minor.
