What is a Copyright Deposit?

This information has been provided by the United States Copyright Office

A deposit is usually one copy (if unpublished) or two copies (if published) of the work to be registered for copyright. In certain cases such as works of the visual arts, identifying material such as a photograph may be used instead. See Circular 40A, Deposit Requirements in Visual Arts Material. The deposit is sent with the application and fee and becomes the property of the Library of Congress.

When registering your copyright, you may deposit an acceptable file type for your sound recording or musical composition.

If your work has been released for publication in a physical format, you will need to deposit 2 copies of your "Best Edition".
