MAPLight.org Combines bill texts and legislative voting records, supporting and opposing interests for each bill, and campaign contribution data. Allows users to see contributions from interests supporting and opposing specific bills; average donations given to legislators, and how those legislators voted on specific bills; timeline of contributions and votes for each bill, identifying when legislators received donations before or after their vote.
GovTrack.us (106th Congress [1999]-present) Includes other information about legislation and members of Congress, including campaign finance information. Allows users to set up "monitors" for online tracking and notification of activity for every person, bill, subject term, or committee in Congress.
