Publication is no longer the key to obtaining federal copyright as it was under the Copyright Act of 1909. However, publication remains important to copyright owners.
The 1976 Copyright Act defines publication as follows:
"Publication" is the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending. The offering to distribute copies or phonorecords to a group of persons for purposes of further distribution, public performance, or public display constitutes publication. A public performance or display of a work does not of itself constitute publication.
A further discussion of the definition of "publication" can be found in the legislative history of the 1976 Copyright Act. The legislative reports define "to the public" as distribution to persons under no explicit or implicit restrictions with respect to disclosure of the contents. The reports state that the definition makes it clear that the sale of phonorecords constitutes publication of the underlying work, for example, the musical, dramatic, or literary work embodied in a phonorecord. The reports also state that it is clear that any form of dissemination in which the material object does not change hands, for example, performances or displays on television, is not a publication no matter how many people are exposed to the work. However, when copies or phonorecords are offered for sale or lease to a group of wholesalers, broadcasters, or motion picture theaters, publication does take place if the purpose is further distribution, public performance, or public display.
