The completion of the copyright by deposit of copies is covered by the provision (sec. 12): "That after copyright has been secured by publication of the work with the notice of copyright as provided in section nine of this Act, there shall be promptly deposited in the Copyright Office or in the mail addressed to the Register of Copyrights, Washington, District of Columbia, two complete copies of the best edition thereof then published, which copies, if the work be a book or periodical, shall have been produced in accordance with the manufacturing provisions specified in section fifteen of this Act; or if such work be a contribution to a periodical, for which contribution special registration is requested, one copy of the issue or issues containing such contribution; or if the work is not reproduced in copies for sale, there shall be deposited the copy, print, photograph, or other identifying reproduction provided by section eleven of this Act, such copies or copy, print, photograph, or other reproduction to be accompanied in each case by a claim of copyright. No action or proceeding shall be maintained for infringement of copyright in any work until the provisions of this Act with respect to the deposit of copies and registration of such work shall have been complied with." {Sidenote: Voiding by failure to deposit} In case of failure to deposit, the law of 1909 provides for penalties and finally voiding of the copyright, as follows (sec. 13): "That should the copies called for by section twelve of this Act not be promptly deposited as herein provided, the Register of Copyrights may at any time after the publication of the work, upon actual notice, require the proprietor of the copyright to deposit them, and after the said demand shall have been made, in default of the deposit copies of the work within three months from any part of the United States, except an outlying territorial possession of the United States, or within six months from any outlying territorial possession of the United States, or from any foreign country, the proprietor of the copyright shall be liable to a fine of one hundred dollars and to pay to the Library of Congress twice the amount of the retail price of the best edition of the work, and the copyright shall become void." {Sidenote: Forfeiture by false affidavit} In the case of a printed book or periodical or of a lithograph or photo-engraving, the copies deposited must be manufactured in America, as set forth in the manufacturing provision (sec. 15) as verified in the case of a book by affidavit (sec. 16) separately treated hereafter, and the book copyright is forfeited (sec. 17) in the event of false affidavit. Thus failure to deposit, and, in the case of books, false affidavit as to American manufacture, are the two lapses of formalities which work forfeiture of copyright. {Sidenote: Works not reproduced}
