U.S. Copyright Office, Circular 34 (rev. 03/2021)
In most cases, the Copyright Office requires each work of authorship to be registered on a separate application. There are, however, limited exceptions to this rule. This circular introduces the Office's practices and procedures for registering multiple works on one application. It covers
As a general rule, a copyright registration covers an individual work, and you must prepare a separate application and submit a separate filing fee and deposit for each work you want to register. There are, however, some limited exceptions to this rule:
If you choose to register multiple works under one of these exceptions and the Copyright Office determines that the works do not qualify, the Office will refuse your application, and you will be required to submit a separate application and filing fee for each individual work.
This circular provides general information on the requirements for registering multiple works with one application and one filing fee.¹ For more information, see chapter 1100 of the Compendium of U.S. Copyright Office Practices.
A collective work is a compilation in which a number of contributions, constituting separate and independent works in themselves, are assembled into a collective whole.
The “authorship” in a collective work comes from the original selection, coordination, and arrangement of the independent works included in the collective work.
Under the Copyright Act, a collective work is considered one work for purposes of registration. A registration for a collective work covers the copyrightable authorship in the selection, coordination, or arrangement of the work. A registration for a collective work covers the collective work as a whole and may cover the individual works contained in it if (1) the collective work and the individual works are owned by the same party, (2) the individual works have not been previously published or previously registered, and (3) the individual works are not in the public domain.
For purposes of registration, representative examples of collective works include
A collective work is not
A contribution to a collective work is a separate and independent work that is included within a collective work. A contribution to a collective work can be registered separately from the collective work or in combination with the collective work if certain requirements are met.
Examples of separate and independent works within a collective work include
A collective work and its individual works can be registered on one application with one filing fee only if
For example, an album that contains multiple sound recordings that embody multiple musical compositions is considered a collective work for purposes of registration. Typically, the party that owns the copyright in the sound recordings also owns the copyright in the album, because that party is usually responsible for creating the album as a whole. If that is the case, the album and the multiple sound recordings can be registered together on one application as a collective work (assuming the recordings have not been published or registered before).
If the copyright owner of the album owns both the sound recordings and the musical compositions that are embodied in each recording, then the album, the musical compositions, and the sound recordings can be registered together on one application as a collective work (assuming the compositions and the recordings have not been published or registered before).
By contrast, if the copyright owner of the album does not own the copyright in the musical compositions (or vice versa), or if the compositions have been previously published, then each composition must be registered separately as an individual contribution to the collective work.
If you submit multiple works with one application, and the Copyright Office determines that the works can be registered together as a collective work, the Office may add an annotation to the certificate, such as “basis for registration: collective work.” As a general rule, the Office will not annotate the certificate if you expressly assert a claim in the “collective work” or the “compilation.”
A collective work is considered a single work for purposes of calculating statutory damages; therefore, registering a collective work together with the individual works contained in it may have important consequences in an infringement action. Section 504(c)(1) of the Copyright Act states that a copyright owner may be entitled to recover “an award of statutory damages for all infringements involved in the [infringement] action, with respect to any one work,” and “[f]or the purposes of this subsection, all the parts of a compilation . . . constitute one work.” The statute also states that a collective work is, by definition, a compilation. Thus, when you register a number of individual works as part of a collective work, you may be entitled to seek one award of statutory damages for the collective work as a whole rather than a separate award for each individual work, even if the defendant infringed all of those works.
The Copyright Office has established an administrative procedure that allows you to register a group of related works in certain limited categories with one application and one filing fee. This procedure is known as a “group registration.”
A group registration covers all the works that are included within the group, provided that you comply with specific requirements.
The Office currently offers group registration options for the following types of works:
See below for more information regarding group registration of unpublished works. For information regarding group registration of newspapers, see Copyright Registration of Newspapers (Circular 62A). For information regarding group registration of contributions to periodicals, see Copyright Registration of Contributions to Periodicals (Circular 62c). For information regarding questions, answers, and other items prepared for use in a secure test, see Copyright Registration of Secure Tests and Secure Test Items (Circular 64). For information about the specific requirements for the remaining group registration options, see chapter 1100 of the Compendium of U.S. Copyright Office Practices.
When the Copyright Office issues a group registration, it prepares one certificate of registration for the entire group and assigns one registration number to that certificate. A registration for a group of unpublished works, a group of unpublished photographs, a group of published photographs, a group of contributions to periodicals, or a group of secure test items covers the copyrightable authorship in each work that has been included in the group, and each work is considered to be registered as a separate work. Similarly, a registration for a group of serials, newspapers, or newsletters covers each issue in the group, and each issue is considered to be registered as a separate work.
These facts may have important consequences in an infringement action. As noted above, section 504(c)(1) of the Copyright Act states that a copyright owner may be entitled to recover “an award of statutory damages for all infringements involved in the [infringement] action, with respect to any one work,” and “[f]or the purposes of this subsection, all the parts of a compilation [collective work] . . . constitute one work.”
A group registration does not create a compilation or collective work for the purposes of section 504, as the group is merely an administrative classification created solely for the purpose of registering multiple works or multiple issues with one application and one filing fee. The selection of the works for group registration is based on the regulatory requirements for group registration options. Any coordination or arrangement of the works is merely an administrative formality that facilitates the examination of the works. In addition, when works are combined for the purpose of registration, they are not recast, transformed, or adapted in any way.
Because a group registration as a whole is not a compilation or a collective work, the Office takes the position that a copyright owner may be entitled to claim a separate award of statutory damages for each work or each issue (in the case of newspapers, newsletters, or serials) covered by a group registration.
NOTE: A database is, by definition, a compilation of digital information. A group registration can cover new updates or revisions to one database during a specified time period. When the database and its updates are registered as a group, the copyright owner is entitled only to one award of statutory damages. For more information on databases, see chapter 700, section 727, of the Compendium.
The Copyright Office has established a group registration option that allows you to register up to ten unpublished works with one application and one filing fee.
To be eligible for a group registration of unpublished works, the following conditions must be met:
Works that do not satisfy these requirements are not eligible for this group registration option.
In particular, you cannot use this option to register a number of published and unpublished works. Likewise, you cannot use this option to register different types of works. For example you may register three poems with the same application, four songs with the same application, or five drawings with the same application, but you cannot register one poem, one song, and one drawing with the same application.
NOTE: There is a limited exception to this rule. You may register up to ten unpublished sound recordings along with the musical, literary, or dramatic works embodied in those recordings if both works are unpublished, if the author(s) and claimant(s) for both works are the same, and if the works are registered in Class SR.
For information about the specific requirements for registering a group of unpublished works, see the Office’s website and tutorial.
A registration for a group of unpublished works or a group of unpublished photographs will remain in effect even if the works included in the group are subsequently published, either separately or together. You can seek another registration for the first published edition of a work in the group. However, it is entirely optional and not necessary to secure the statutory benefits of registration.
The Copyright Office has established an administrative procedure that allows you to register a number of published works on one application with one filing fee provided that the works were physically packaged or bundled together as a single unit and that they were first published in that integrated unit. Such a registration is known as the “unit of publication” option.
A unit of publication is a physical package that contains a number of separately fixed works that have been physically bundled together for distribution to the public as a single, integrated unit.
The following are representative examples of separately fixed works that could be considered a unit of publication:
The requirements for registering a number of works as a unit of publication are very specific, and most works do not qualify for this option. You can use it only if
You can use the unit of publication option if the copyright claimant is the party primarily responsible for manufacturing, producing, publishing, packaging, or otherwise creating the single, integrated unit. However, the unit cannot have been created solely for the purpose of registering the works with the Copyright Office; instead, the works must have been distributed to the general public within that single, integrated unit.
The following are representative examples of works that cannot be registered as a unit of publication:
For additional information concerning the requirements for registering a unit of publication, see chapter 1100, section 1107, of the Compendium.
The Copyright Office has established an administrative procedure that allows you to register a sound recording together with the musical, literary, or dramatic work embodied in that recording. You can register these works together on one application with one filing fee only if
