From THOMAS at the Library of Congress -- legislative information: laws, bills, hearings. You name it, it's here.
Legislation, case law, and legislative codes and regulations are freely available on the Internet. However, what YOU want is not always EASY to find. Lexis-Nexis or Westlaw can help you pinpoint the information you want.
Lexis Nexis has a ton of great information, but it can be a bit confusing to find.
Check under the blue sources button on the left hand side of the page to find the codes from particular courts, administrative units (e.g., Attorney Generals's offices, the House of Representatives, the Senate, law reviews.)
