The Library of Congress occupies three buildings on Capitol Hill. The Thomas Jefferson Building (1897) is the original separate Library of Congress building. (The Library began in 1800 inside the U.S. Capitol.) The John Adams Building was built in 1938 and the James Madison Memorial Building was completed in 1981. Other facilities include the High Density Storage Facility (2002) at Fort Meade, Md., and the Packard Campus for Audio Visual Conservation (2007) in Culpeper, Va.
Today's Library of Congress is an unparalleled world resource. The collection of more than 167 million items includes more than 39 million cataloged books and other print materials in 470 languages; more than 72 million manuscripts; the largest rare book collection in North America; and the world's largest collection of legal materials, films, maps, sheet music and sound recordings.
