The Library of Congress is the research library that officially serves the United States Congress and is the de facto national library of the United States. It is the oldest federal cultural institution in the United States.
The library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains the National Audio-Visual Conservation Center in Culpeper, Virginia. The library's functions are overseen by the librarian of Congress, and its buildings are maintained by the architect of the Capitol. The Library of Congress is one of the largest libraries in the world. Its "collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 450 languages." Congress moved to Washington, D.C., in 1800 after sitting for 11 years in the temporary national capitals in New York City and Philadelphia. In both cities, members of the U.S. Congress had access to the sizable collections of the New York Society Library and the Library Company of Philadelphia. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s.
