by Registering Your Work
If you receive a written notice from the Copyright Office for a work subject to mandatory deposit, you must respond within three months by submitting the required number of copies or by registering your work with the Copyright Office. This circular provides instructions when you respond to a notice by registering your work. It covers
All works under copyright protection that are published in the United States are subject to the “mandatory deposit” provision of the copyright law. As a general rule, it requires that two copies of the “best edition” of a copyrightable work published in the United States be sent to the Copyright Office within three months of publication. The Office can issue a written demand for copies or phonorecords for the Library of Congress at any time after a work has been published in the United States. When you receive such a demand notice, you must respond within three months by submitting the required number of copies or by registering your work with the Copyright Office. This circular covers the process for responding to a written notice by registering your work.
For more information about mandatory deposit, see Mandatory Deposit of Copies or Phonorecords for the Library of Congress (Circular 7D) or contact the Copyright Acquisitions Division at cad@copyright.gov or (202) 707-7125.¹

The Copyright Acquisitions Division will forward your submission to the Registration Program once it is received.
To avoid damage to your deposit from mail security measures in effect on Capitol Hill, where the Copyright Office is located, package microform deposits and electronic media such as CDs and DVDs in boxes weighing no more than twenty pounds each rather than in envelopes. CDs and DVDs packaged in standard-size jewel cases are more likely to survive security measures, which include an irradiation process, than those packaged in slim-line cases.
NOTE: We recommend that you send your package using a traceable mail method. This will allow us to confirm delivery of the shipment.
