In the United States, the [[Copyright Act of 1976|Copyright Act]] requires that any copyrighted and published work must be submitted in two copies to the [[United States Copyright Office]] at the [[Library of Congress]]. The Library of Congress does not retain all works.<ref>{{cite web|url=http://www.copyright.gov/circs/circ07d.pdf|title=Library of Congress Mandatory Deposit Rules|access-date=28 January 2018}}</ref> This mandatory deposit is not required to possess copyright of unpublished works, but a [[copyright registration]] can give an author enhanced remedies in case of a copyright violation.<ref>{{cite web|url=http://www.copyright.gov/register/|title=U.S. Copyright Office - Online Services (eCO: Electronic Copyright Office)<!-- Bot generated title -->|access-date=28 January 2018}}</ref> This optional registration also requires depositing two copies of the work and therefore also satisfies mandatory deposit requirements. If a foreign publisher distributes works in the US, they must also comply with the mandatory requirements.<ref>{{Cite web|url=https://www.copyright.gov/help/faq/mandatory_deposit.html|title=Mandatory deposit|date=n.d.|website=US Copyright Office|access-date=October 13, 2019}}</ref>

In August 2023, the [[United States Court of Appeals for the District of Columbia Circuit]] ruled that the mandatory deposit requirement is an unconstitutional violation of property rights. The separate deposit requirement to optionally register copyright, however, remains in place.<ref>{{cite web|url=https://www.reuters.com/legal/litigation/us-appeals-court-curbs-copyright-offices-mandatory-deposit-policy-2023-08-29/|title=US appeals court curbs Copyright Office's mandatory deposit policy |publisher=Reuters |access-date=13 September 2023}}</ref><ref>{{cite court |litigants=Valancourt Books, LLC v.

Another type of depository library in the United States are [[Federal depository library|federal depository libraries]], which are entitled to free copies of all materials (digital, print, microform, etc.) published by the [[United States Government Publishing Office|Government Publishing Office]]. By accepting these materials, the libraries commit to providing free public access to the depository collection, and they agree to hold the materials for no fewer than five years (with some exceptions); large "regional" depositories also commit to holding these materials indefinitely. There are currently 1,114 such depository libraries in the United States, though the number of federal publications each receives varies based upon their selection profile.<ref>{{Cite web |url=https://catalog.gpo.gov/fdlpdir/ |title=FDLP Library Directory|website=catalog.gpo.gov}}</ref> This [[Federal Depository Library Program]] (FDLP) is not affiliated with the Library of Congress and should not be confused with the aforementioned copyright deposit program.
