Responding to a Demand for Mandatory Deposit

if You Choose to Register Your Work

Copyright registration provides legal benefits to copyright owners. If you receive a Demand for Mandatory Deposit and would like to register your work at the same time as you deposit the required copies, this circular provides instructions for how to do so. It covers

  1. Packaging an electronic shipping slip with a physical deposit when you register online
  2. Bundling a deposit and filing fee with a paper application

All copyright-protected works published in the United States are subject to the mandatory deposit provision of the copyright law. As a general rule, the law requires depositing two copies of the best edition with the Copyright Office within three months of publication in the United States. The Office may issue a Demand for Mandatory Deposit any time after a work has been published in the United States. If you receive a demand, you must respond within three months by submitting the required number of copies. You may also submit these copies in support of an application for registration, which provides additional legal benefits. This circular covers the process for responding to a demand by applying to register the copyright in your work and submitting the required copies.

For more information about mandatory deposit, see Mandatory Deposit of Copies or Phonorecords for the Library of Congress (Circular 7D) (PDF, 230KB) or contact the Acquisitions & Deposits division at ad@copyright.gov or (202) 707-7125.¹

Mail security measures

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.

PLEASE NOTE: 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.
