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, 18—, 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. Since the phrase, _all rights reserved_, refers exclusively to the author’s right to dramatize or to translate, it has no bearing upon any publications except original works, and will not be entered upon the record in other cases. 6. The original term of copyright runs for 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. Applications for renewal must be accompanied by explicit statement of ownership, in the case of the author, or of relationship, in the case of his heirs, and must state definitely the date and place of entry of the original copyright. Advertisement of renewal is to be made within two months of date of renewal certificate, in some newspaper, for four weeks. 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.
