Library of Congress

Established in 1800, the Library of Congress ranks as one of the largest and finest in the world.

Although founded primarily to serve the Congress, its field of service gradually expanded to serve all government agencies, serious scholars, other libraries and the general public. The Library was originally located in the Capitol but by 1881 it was apparent that a spate building was needed to house its expanding collections and activities. The Jefferson Building was constructed between 1886 and 1897. (Smithmeyer & Pelz; Edward P. Casey, architects)
