In the case of works not reproduced for sale, copyright may be secured under the provision (sec. 11): "That copyright may also be had of the works of an author of which copies are not reproduced for sale, by the deposit, with claim of copyright, of one complete copy of such work if it be a lecture or similar production or a dramatic or musical composition; of a photographic print if the work be a photograph; of a photograph or other identifying reproduction thereof if it be a work of art or a plastic work or drawing. But the privilege of registration of copyright secured hereunder shall not exempt the copyright proprietor from the deposit copies under sections twelve and thirteen of this Act where the work is later reproduced in copies for sale." The entire work should in each case be deposited (C. O. Rule 18) and not a mere outline, epitome or scenario; and the copy should be in convenient form, clean and legible, with the leaves securely fastened together, and should bear the title of the work exactly as given in the application. {Sidenote: Second registration} It should be noted that in this class of copyright, which is a common law copyright fortified by statutory protection, an ideal example of copyright law, double registration is required in case the unpublished copyrighted work is published, requiring one application fee and deposit of one identifying copy for the unpublished work and a second application fee and deposit of two copies promptly after publication. {Sidenote: Free transportation in mail} It should be noted that the deposit copies may be deposited either in the Copyright Office or "in the mail addressed to the register of copyrights," and it is provided (sec. 14): "That the postmaster to whom are delivered the articles deposited as provided in sections eleven and twelve of this Act shall, if requested, give a receipt therefor and shall mail them to their destination without cost to the copyright claimant." Franking labels are not required and are no longer issued by the Copyright Office. Deposit copies, and all mail matter, should be addressed to the "Register of Copyrights, Library of Congress, Washington, D. C.," and not to any person by name. {Sidenote: Loss in mail} Thus even if the deposit copies should not reach Washington, as in case they were burned in the mail, the copyright proprietor can validate his claim by production of the postmaster's receipt in lieu of deposit copies. {Sidenote: Foreign works}
