Identifying Material

Copyright Office regulations require the deposit of identifying material instead of copies for three-dimensional works and for works that have been applied to three-dimensional objects.

In certain cases, identifying material is permitted; in other cases, it is required. Identifying material should meet the following specifications:

Type of identifying material
The material should consist of photographic prints, transparencies, photocopies, drawings, or similar two-dimensional reproductions or renderings of the work, in a form visually perceivable without the aid of a machine or device.
Color or black and white
If the work is a pictorial or graphic work, the material should reproduce the actual colors employed in the work. In all other cases, the material may be in black and white or may consist of a reproduction of the actual colors.
As many pieces of identifying material should be submitted as are necessary to show clearly the entire copyrightable content of the work for which registration is being sought.
Number of sets
Only one set of complete identifying material is required. NOTE: With respect to three-dimensional holograms, please write the Copyright Office for additional information.
Photographic transparencies must be at least 35 mm in size and, if 3 x 3 inches or less, must be fixed in cardboard, plastic, or similar mounts; transparencies larger than 3 x 3 inches should be mounted. All types of identifying material other than photographic transparencies must be not less than 3 x 3 inches and not more than 9 x 12 inches, but preferably 8 x 10 inches. The image of the work should show clearly the entire copyrightable content of the work.
Title and dimension
At least one piece of identifying material must give the title of the work on its front, back, or mount and should include an exact measurement of one or more dimensions of the work.
