In case of a printed book the copies deposited must be accompanied with the affidavit called for by House bill 13355, passed by the House April 26, 1904, that the requirements as to American typesetting, etc., have been complied with, and the affidavit is to specify the place and the establishment in which the work was done. Extends [sec. 13] the "manufacturing clause" to include texts produced by lithographic process, and also in certain cases illustrations and separate lithographs, but abrogates it in the case of photographs. The articles required to be deposited are to be entitled to free transmittal through the mails, as under earlier statutes (e.g., act of February 18, 1867; July 8, 1870). [Sec. 12.] The notice of copyright simplified. Specified only for the copies "published or offered for sale in the United States." Where right of public performance is reserved on musical compositions, a notice to this effect is required. [Sec. 14.] _Ad interim term_ [_sec. 16_].--Extends the ad interim term of protection in the case of books first published abroad in foreign languages from one year to two years. Provides for an ad interim term in the case of books first published abroad in English, of thirty days, but with prohibition of importation during the interim. _Duration_ [_sec. 18_].--Instead of the present term (forty-two years), varying terms according to the subject-matter. Provides a special term of twenty-eight years (instead of forty-two years as now) for labels and prints heretofore registered in the Patent Office; increases the term of other articles, and especially derivative articles, from forty-two years to fifty years; and in the case of original works increases the term to the life of the author and fifty years. Abolishes renewals. The bill also makes provision for the extension of subsisting copyrights to agree with the term provided in the present bill where the author is living or his widow or a child, provided the publisher or other assignee joins in the application for such extension. (See section 19 of the draft.) The right of dramatization or translation must be exercised within ten years or it will lapse. _Protection of copyright._--The present statute (Rev. Stat., sec. 4965) attempts to define acts which shall constitute infringements. The bill, having defined the exclusive rights which the copyright has secured to the author, defines (sec. 23) infringement as "doing or causing to be done" without his consent "any act the exclusive right to do or authorize which" is "reserved" to him. It contains, however (sec. 22), the one specification that "any reproduction" without his consent "of any work or any material part of any work" in which copyright is subsisting, shall be illegal and is prohibited.
