Deposit Copy

A deposit copy is a physical or digital copy of a copyrighted work submitted to the U.S. Copyright Office as part of the copyright registration process. Required under the Copyright Act, it serves as the official record of the work being registered and is retained by the Library of Congress for archival and public access purposes.

How the deposit copy requirement works

When filing a copyright registration, the applicant must submit an application form, the required filing fee, and one or more deposit copies. The number and format required depend on the type of work and whether it has been published.

For most published works, two complete copies of the best edition must be deposited. For unpublished works, one complete copy is generally sufficient. "Best edition" refers to the highest-quality version of the work available at the time of registration, as defined by the Copyright Office.

Deposits are submitted through the Copyright Office's online eCO system or by mail. Once processed, deposit copies are transferred to the Library of Congress, where they become part of the permanent national collection and are not returned to the copyright owner.

Key characteristics

• Not returned. Deposit copies become property of the Library of Congress upon submission.
• Format requirements vary. The Copyright Office publishes regulations specifying acceptable formats for different types of work.
• Special relief is available. Copyright owners who cannot deposit the full work due to cost, size, or proprietary concerns may apply for an exemption or alternative deposit format before filing.
• Mandatory deposit is separate from registration. Under § 407, publishers must deposit copies within three months of U.S. publication regardless of whether they register. Noncompliance after a written demand can result in a $250 fine per work.

Why the deposit copy matters

The deposit copy serves two legal functions. First, it documents the specific content of the work at the time of registration, which can be critical evidence in an infringement dispute. Second, it fulfills the mandatory deposit obligation under 17 U.S.C. § 407, which requires publishers of works distributed in the United States to deposit copies with the Library of Congress even if they never seek formal registration.

Submitting an incorrect or incomplete deposit copy can result in the Copyright Office rejecting or delaying a registration. It may also weaken enforcement rights, since timely registration with a proper deposit is required to recover statutory damages and attorneys' fees.

Common examples

• Books: A publisher submits two printed copies of the best edition alongside the registration application
• Software: Developers may deposit only the first and last 25 pages of source code rather than the full program, due to proprietary concerns
• Sound recordings: A recording artist deposits a copy of the final mixed and mastered audio file or physical release

In each case, the deposit copy must accurately represent the work as it exists at the time of registration. Submitting a draft or incomplete version can create problems if the registration is later challenged.

FAQs about deposit copy

Is the mandatory deposit obligation separate from copyright registration?

Yes. A deposit is required regardless of whether the copyright owner seeks formal registration. The obligations run on parallel tracks, and noncompliance with a Copyright Office demand carries fines.

Can a copyright owner retrieve a deposit copy after submission?

No. Once transferred to the Library of Congress, deposit copies become part of the national collection and are never returned. Copyright owners should retain their own copies of exactly what was submitted.

What happens if the deposit copy doesn't match the final published work?

The deposit copy establishes the work's content as it existed at the time of registration. A mismatch can create evidentiary problems in an infringement dispute. If a work undergoes material changes after registration, a new registration may be needed to protect the updated content.
