604.6 Annotations Are Part of the Registration Record
An annotation is part of the registration record and a correct annotation generally will not be removed from the registration record once a registration has been made.
The U.S. Copyright Office will retain supporting documentation for an annotation (or amendment), such as an email, cover letter, fax, or note regarding a phone call. Both the certificate of registration and the online public record will indicate that correspondence relating to the claim is in the file.
