"The Library of Congress is the nation's oldest federal cultural institution and serves as the research arm of Congress. It is also the largest library in the world, with millions of books, recordings, photographs, maps and manuscripts in its collections. The Library's mission is to support the Congress in fulfilling its constitutional duties and to further the progress of knowledge and creativity for the benefit of the American people." loc.gov
Presented by the Library of Congress, Congress.gov is the official online portal for U.S. federal legislative information, including current and recent legislation, schedules, and representatives.
In 1832, Congress established the Law Library of Congress as a separate department of the Library. It houses one of the most complete collections of U.S. Congressional documents in their original format. In order to make these records more easily accessible to students, scholars, and interested citizens, A Century of Lawmaking for a New Nation brings together online the records and acts of Congress from the Continental Congress and Constitutional Convention through the 43rd Congress, including the first three volumes of the Congressional Record, 1873-75.
