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. 17 USC

The act by which a thing is made public and differing from promulgation.Publication has different meanings. When applied to a law, it signifies the rendering public the existence of the law; when it relates to the opening the depositions taken in a case in chancery, it means that liberty is given to the officer in whose custody the depositions of witnesses in a cause are lodged, either by consent of parties, or by the rules or orders of the court, to show the depositions openly, and to give out copies of them. When it refers to a libel, it is its communication to a second or third person, or a greater number. And when spoken of a will, it signifies that the testator has done some act from which it can be concluded that he intended the instrument to operate as his will.
