Below is a excerpt from an article written by Josh Schiller, which was published in the Washington Post. The article has to do with “Unpublished Works”.
“A few months after King delivered the speech, he sent a copy of the address to the U.S. Copyright office and listed the remarks as a “work not reproduced for sale.” In legal terms, this is also known as an unpublished work. He subsequently sued to enjoin two publishers from distributing phonographic reproductions of the address. One of the defendants, 20th Century Fox, had filmed and broadcast all of the speeches at the March on Washington at the request of the march’s organizers. From that material, it had reproduced the phonographs that were the subject of the injunction. But a court ruled that, although King had addressed a large public audience in an unrestricted public forum, reproduction without authorization was an infringement of King’s copyright. Performance of the speech, like the performance of a song or play in a public space, did not create a general waiver of King’s right to limit reproduction under the 1909 Copyright Act.”
