Administrative Copyright Classification Systems
The classification system employed by the Copyright Office to further identify the form of a given deposit
has always been an internal policy, considered part of the Office “housekeeping, and considered not to have
any bearing on the copyright itself. It can be a very useful tool in limiting searches and identifying sparsely
cataloged entries with few descriptors. The system has evolved over the years; new classes were established
and older designations were phased out. As a response to Revision and to make as clean a break as possible
between old law” and “new law” registrations, the Copyright Office developed the following system which
went into effect on January 1, 1978:
Class TX: Nondramatic Literary Works
This category is very broad. Except for dramatic works and certain kinds of audiovisual works, Class TX
included all types of published and nonpublished works written in words (or other verbal or numerical
symbols). A few of the many examples of “nondramatic literary works” include: fiction, nonfiction, poetry,
periodicals, textbooks, reference works, directories, catalogs, advertising copy, and compilations
of information.
Class PA: Works of the Performing Arts
This category includes published and unpublished works prepared for the purpose of being “performed”
directly before an audience of indirectly “by means of any device or process”. Examples of works of the
performing arts are: musical works, including any accompanying words; dramatic works, including any
accompanying music; pantomimes and choreographic works; and motion pictures and other audiovisual
works.
Class VA: Works of the Visual Arts
This category consists of published and unpublished pictorial, graphic, or sculptural works”, including
two-dimensional and three-dimensional works of fine, graphic, and applied art, photographs, prints and art
reproductions, maps, globes, charts, technical drawings, diagrams, and models. Within this class are pictorial
or graphic labels and advertisements, as well as “works of artistic craftsmanship”. The design of a useful
article” may be registrable in Class VA, but only if, and only to the extent that, such design incorporates
pictorial, graphic, or sculptural features that can be identified separately from, and are capable of existing
independently of, the utilitarian aspects of the article”.

Administrative Copyright Classication Systems
Class SR: Sound Recordings
This category is appropriate for registration for both published and unpublished works in two situations: (1)
where the copyright claim is limited to the sound recording itself; and (2) where the same copyright claimant
is seeking to register not only the sound recording but also the musical, dramatic, or literary works embodied
in the sound recording. With one exception, “sound recordings” are works that result from the fixation of
a series of musical, spoken, or other sounds. The exception is for the audio portions of audiovisual works,
such as a motion picture soundtrack or an audio cassette accompanying a filmstrip; these are considered an
integral part of the audiovisual work as a whole and are registrable in Class PA. Sound recordings fixed before
February 15, 1972 are not eligible for registration, but may be protected by State law.
Class RE: Renewal Registration
This category covers renewal registration for copyrights that are already in their first term on January 1, 1978
(that is, renewals for works originally copyrighted between January 1, 1950 and December 31, 1977). Class RE
is appropriate for all renewal registrations, regardless of the class in which the original registration was made.
In dealing with pre-1978 registrations, it is necessary to be aware of the administrative classes that had evolved
prior to Revision. The following is a brief description of each class, along with a history of numbering
systems. NOTE: None of these classes are in effect at the present time. If a class was phased out prior to
December 31, 1977, the end date is indicated.
