Welcome Message from the Librarian of Congress
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.
As Librarian of Congress, I oversee the many thousands of dedicated staff who acquire, catalog, preserve, and make available library collections within our three buildings on Capitol Hill and over the Internet. I am pleased that you are visiting our Web site today, and I invite you return to it often.
James H. Billington
