Copyright Law of the United States of America / Contained in Title 17 of the United States Code

The United States Copyright Office (sometimes abbreviated USCO), a part of the Library of Congress, is the official U.S. government body that maintains records of copyright registration in the United States, including a Copyright Catalog. It is used by copyright title searchers who are attempting to clear a chain of title for copyrighted works.

The head of the Copyright Office is called the Register of Copyrights. The Acting Register is Karyn Temple Claggett, who replaced Maria Pallante upon her departure in October 2016.
