Usually, copyrights must be registered individually. Sometimes, though, the copyrights in a group of works may be registered together.
Unpublished works
Up to 10 unpublished works can be registered together using the U.S. Copyright Office’s Group Registration of Unpublished Works (GRUW ) application. They must all be created by the same author or joint authors, be in the same category of works, and be unpublished. The creator(s) must be the claimant(s). A single GRUW application is used, but each work must be uploaded as an individual, separate file. The requirement that the works must be in the same category means that they must all be literary works, or they must all be musical works, or they must all be photographs, etc. You cannot use the GRUW application to register a song and nine drawings together, for example.
Music albums
Group registration of musical works on an album also is permitted. Up to 20 musical works published on the same album may be registered together using the Group Registration of Musical Works on an Album (GRAM ) application, provided each song has at least one common author. All of the works must be first published on the same album on the same date. A work that is included in the album and that was previously published as a single may be included, however, so long as it was never published on an album before. You may also file an application to register copyrights in a group of sound recordings on a music album using the GRAM application. Similar eligibility criteria apply.
Photographs, artwork, short online literary works, and other group registration options
Options also exist for group registration of photographs (published or unpublished), published artwork (GR2D ), newspapers, periodicals, updates to a news website (GRNW ), contributions to periodicals (GRCP ), short online literary works (GRTX ), and some other kinds of works. The option to register a group of short online literary works together using the Group Registration for Short Online Works (GRTX) option is a real boon for bloggers, social media influencers, and owners of frequently updated websites.
