U.S. Copyright OfficeFor over 150 years, the Copyright Office has been at the forefront of U.S. copyright. As part of the Library of Congress since 1870, and recognized by Congress as a separate department of the Library since 1897, the Copyright Office registers copyright claims, records information about copyright ownership, provides information to the public, and assists Congress and other parts of the government on a wide range of copyright issues, both simple and complex.
