Corrections & Amplifications of Existing Registrations

To correct an error in a copyright registration or to amplify the information given in a registration, file a supplementary registration form–Form CA– with the Copyright Office. The filing fee is $100. (See Note above.) The information in a supplementary registration augments but does not supersede that contained in the earlier registration. Note also that a supplementary registration is not a substitute for an original registration, for a renewal registration, or for recording a transfer of ownership. For further information about supplementary registration, request Circular 8, "Supplementary Copyright Registration."

Mandatory deposit for works published in the United States

Although a copyright registration is not required, the Copyright Act establishes a mandatory deposit requirement for works published in the United States. See the definition of "publication." In general, the owner of copyright or the owner of the exclusive right of publication in the work has a legal obligation to deposit in the Copyright Office, within 3 months of publication in the United States, two copies (or in the case of sound recordings, two phonorecords) for the use of the Library of Congress. Failure to make the deposit can result in fines and other penalties but does not affect copyright protection.

Certain categories of works are exempt entirely from the mandatory deposit requirements, and the obligation is reduced for certain other categories. For further information about mandatory deposit, request Circular 7d, "Mandatory Deposit of Copies or Phonorecords for the Library of Congress."

Use of mandatory deposit to satisfy registration requirements

For works published in the United States, the copyright law contains a provision under which a single deposit can be made to satisfy both the deposit requirements for the Library and the registration requirements. In order to have this dual effect, the copies or phonorecords must be accompanied by the prescribed application form and filing fee.
