2410 Full-Term Retention of Deposits
As a general rule, the U.S. Copyright Office will retain the deposit copy(ies) or identifying material for an unpublished work for the full term of the copyright.
The deposit for a published work may be retained under the control of the Office for the longest period considered practicable and desirable by the Register of Copyrights and the Librarian of Congress. At the end of this period, the work may be destroyed.
Upon request and payment of the appropriate fee, the Office will retain the deposit copies for a published work for a period of seventy-five years from the date of publication. This service is known as “full-term retention.”
