Periodicals, as well as books, are subject to the manufacturing clause (sec. 15), but affidavit is not required, and the importation of "a foreign newspaper or magazine, although containing matter copyrighted in the United States printed or reprinted by authority of the copyright proprietor," is not prohibited (sec. 31, b), "unless such newspaper or magazine contains also copyright matter printed or reprinted without such authorization"--but these and other conditions are treated in later chapters. {Sidenote: Periodicals copyrightable by numbers} The law provides (sec. 19) in the case of a periodical, that the notice of copyright may be "either upon the title-page or upon the first page of text of each separate number or under the title heading," "provided that one notice of copyright in each volume or in each number of a newspaper or periodical published shall suffice." This implies that each issue of a periodical must be separately copyrighted as though a separate work, although the title may be registered as a trade-mark and possibly protected in this way. A daily newspaper may thus be copyrighted day by day at a cost of $365 per year, so as to protect all its original material of substantial literary value. This was done in fact under the American law previous to 1909, though periodicals were not specifically mentioned; a daily price-list of the New York Cotton Exchange was so entered day by day, but the question of maintaining such a copyright under the old law seems never to have been tested in the courts, and New York dailies copyrighted their Sunday cable letters separately. {Sidenote: News} In respect to news, there is no provision in the new code. A bill to protect news for twenty-four hours was at one time before Congress, but was never passed. There is, therefore, no copyright protection for news as such, but the general copyright of the newspaper or a special copyright may protect the form of a dispatch, letter, or article containing news. Thus the New York _Herald_ copyrighted without question Dr. Cook's Arctic dispatches, and the question as to the copyright by the New York _Times_ of Commander Peary's dispatches describing his dash for the pole hinged solely on the question of ownership or authority to copyright, as set forth in a later chapter. But any such copyright could not prevent publication by other newspapers of the news that Cook and Peary claimed to have reached the North Pole, at stated dates and under stated circumstances, though their own form of statement of the facts could not lawfully be copied except within "fair use."
