Welcome Message from the Librarian of Congress
Dr. James H. Billington
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 more than 130 million items on approximately 530 miles of bookshelves. The collections include more than 29 million books and other printed materials, 2.7 million recordings, 12 million photographs, 4.8 million maps, and 58 million manuscripts.
The Library's mission is to make its resources available and useful to the Congress and the American people and to sustain and preserve a universal collection of knowledge and creativity for future generations. The Office of the Librarian is tasked to set policy and to direct and support programs and activities to accomplish the Library's mission.
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 to bookmark our URL (统一资源定位器) and return to it often.
Sincerely,
James H. Billington
