By the operation of the copyright law, any publisher, author, or artist desiring to obtain an exclusive privilege of issuing any publication whatever, must send two copies of the publication on which a copyright is asked to the Librarian of Congress to be deposited in the Library. By this means, during the twenty-five years that the law has been in force, the Library has been enabled to accumulate approximately the entire current product of the American press, as well as an enormous number of photographs, engravings, and other works coming under the head of fine arts. The possession of this material would alone give the Library a special national character possible to no other library in the country. HISTORY OF THE LIBRARY. The Library of Congress was founded in the year 1800, about the time that the government was first established in Washington. Five thousand dollars was the first appropriation, made April 24, 1800, while Congress was still sitting in Philadelphia. Some of the Democratic Congressmen, as strict constructionists, opposed the idea of a governmental library, but their party leader, Thomas Jefferson, then President, warmly favored it. He called it, later in life, with a sort of prophetic instinct, the “Library of the United States,” and his support of it from the very beginning was so hearty and consistent that he may perhaps be regarded in the broad sense as the real founder of the institution. The Library was shelved from the first in a portion of the Capitol building. The first catalogue was issued in April, 1802. It appears that there were then, in accordance with the old-fashioned method of dividing books according to size, not subject, 212 folios, 164 quartos, 581 octavos, 7 duodecimos, and 9 maps.
