(3). Within ten days after publication of each book or other article, two complete copies of the best edition issued must be sent, to perfect the copyright, with the address Librarian of Congress, Washington, D. C.
The postage must be prepaid, or else the publication enclosed in parcels covered by printed Penalty Labels, furnished by the Librarian, in which case they will come free by mail, according to rulings of the Postoffice Department. Without the deposit of copies above required the copyright is void, and a penalty of $25 is incurred. No copy is required to be deposited elsewhere.
(4). No copyright is valid unless notice is given by inserting in every copy published, on the title page or the page following, if it be a book; or if a map, chart, musical composition, print, cut, engraving, photograph, painting, drawing, chromo, statue, statuary, or model or design intended to be perfected as a work of the fine arts, by inscribing upon some portion thereof, or on the substance on which the same is mounted, the following words, viz: "Entered according to act of Congress, in the year——by——, in the office of the Librarian of Congress, at Washington," or, at the option of the person entering the copyright, the words: "Copyright, 19—, by——."
The law imposes a penalty of $100 upon any person, who has not obtained copyright, who shall insert the notice "Entered according to act of Congress," or "Copyright," etc., or words of the same import, in or upon any book or other article.
(5). Any author may reserve the right to translate or to dramatize his own work. In this case, notice should be given by printing the words "Right of translation reserved," or "All rights reserved," below the notice of copyright entry, and notifying the Librarian of Congress of such reservation, to be entered upon the record.
(6). Each copyright secures the exclusive right of publishing the book or article entered for the term of twenty-eight years. Within six months before the end of that time, the author or designer, or his widow or children, may secure a renewal for the further term of fourteen years, making forty-two years in all. Application for renewal must be accompanied by explicit statement of ownership, in the case of the author, or of relationship, in the case of heirs, and must state definitely the date and place of entry of the original copyright.
(7). The time within which any work entered for copyright may be issued from the press is not limited by any law or regulation, but depends upon the discretion of the proprietor. A copyright may be secured for a projected work as well as for a completed one.
(8). A copyright is assignable in law by any instrument of writing, but such assignment must be recorded in the office of the Librarian of Congress within sixty days from its date. The fee for this record and certificate is one dollar, and for a certified copy of any record of assignment one dollar.
(9). A copy of the record (or duplicate certificate) of any copyright entry will be furnished, under seal, at the rate of fifty cents each.
(10). In the case of books published in more than one volume, or of periodicals published in numbers, or of engravings, photographs, or other articles published with variations, a copyright is to be entered for each volume or part of a book, or number of periodical, or variety, as to style, title, or inscription, of any other article.
