The U.S. Copyright Office has added to the Interent Archive seven volumes of Catalogs of Copyright Entries (CCE), which were published by the Copyright Office from July 1891 through December 1977. The CCE volumes contain data on copyright registration, and are a useful tool for tracking down copyright owners.
Although the current collection is simply digitized versions of the print catalogs, the Copyright Office has long-term plans to turn these records into a searchable database, and they are accepting capability statements from groups that are able to undertake this project.
