The American law formerly named "the author, inventor, designer, or proprietor of any work, and the executors, administrators, or assigns of any such person" as the persons in whom copyright may lodge. The Librarian of Congress accordingly issued copyright certificates for books as to an "author" or "proprietor" only, assuming usually that an editor was the "author" and a publisher the "proprietor," and never going behind the claim set forth in the application. Under the new law the applicant is designated only as the "claimant," and no such distinction is made, except that the Copyright Office has an index card for proprietor, as well as author, when another than the author makes the application. {Sidenote: The author primarily} The author is the person primarily entitled to copyright. He may sell or otherwise transfer his production before it is copyrighted, in which case the new proprietor obtains all the common law rights of property, both in the manuscript and its publication, including the right to copyright. This common law right, including the right to copyright, may extend, Drone argues, to the finder of an unpublished manuscript, provided no one successfully disputes his ownership of his find, if the manuscript be copyrightable; but there are no decisions on this point. If a copyright is taken out by another person (as the publisher of the book), it is done impliedly in trust for the author, as is a usual custom among American publishers. The proprietor is defined to mean "the representative of an artist or author who might himself obtain copyright." {Sidenote: Claimant's right to register}
