A bill, or legislation, is a proposal for congressional action. A bill is introduced in either the House or the Senate. There are four types of legislation:
Federal bills can be found in print and microfiche in the Law Library of Congress (see list of titles below which link to bibliographic information in the LIbrary of Congress Online Catalog). Bills and resolutions from the 1st through the 72nd Congress (1789-1932) are available on microfilm under the call number LL-01. Those from the 73rd to the 109th (1933-2006) are on microfiche and have the call number LL-F-21. The Law Library of Congress also has print bills. House bills go back to the second term of the 6th Congress (1800) and those for the Senate date back to the second term of the 18th Congress (1824).
There are several free websites that provide access to Federal bills and resolutions.
The subscription resources marked with a padlock are available to researchers on-site at the Library of Congress. If you are unable to visit the Library, you may be able to access these resources through your local public or academic library.
