According to Black’s Law Dictionary, a “disclosure” is a revelation of facts or act or process of making known something that was previously unknown. In the field of copyright, “disclosure” may mean making a work accessible to the public for the first time.  First publication of works is one—but not the only possible—form of disclosure, since works may also be disclosed through non-copy related acts, such as public performance, and broadcasting to the public by cable (wire).  Recognition of such a right is not an obligation under international copyright norms.  The Berne Convention for the Protection of Literary and Artistic Works (1971), refers to the use of publicly disclosed works in the context of exceptions, and the author has the right to disclose his work to the world.  Under certain national laws, the “right of disclosure” is a moral right.
