Library of Congress
The Library was founded in 1800, making it the oldest federal cultural institution in the nation. On August 24, 1814, British troops burned the Capitol building (where the Library was housed) and destroyed the Library's core collection of 3,000 volumes. On January 30, 1815, Congress approved the purchase of Thomas Jefferson’s personal library of 6,487 books for $23,950.
The Library of Congress is the largest library in the world, with more than 158 million items on approximately 838 miles of bookshelves. The collections include more than 36 million books and other print materials, 3.5 million recordings, 13.7 million photographs, 5.5 million maps, 6.7 million pieces of sheet music and 69 million manuscripts.
The Library receives some 15,000 items each working day and adds approximately 12,000 items to the collections daily. The majority of the collections are received through the Copyright registration process, as the Library is home to the U.S. Copyright Office. Materials are also acquired through gift, purchase, other government agencies (state, local and federal), Cataloging in Publication (a pre-publication arrangement with publishers) and exchange with libraries in the United States and abroad. Items not selected for the collections or other internal purposes are used in the Library’s national and international exchange programs. Through these exchanges the Library acquires material that would not be available otherwise. The remaining items are made available to other federal agencies and are then available for donation to educational institutions, public bodies and nonprofit tax-exempt organizations in the United States.
