In respect to foreign works, it should be noted that "the original text of a work of foreign origin in a language or languages other than English," may be formally copyrighted and fully protected by registration under the same formalities as domestic works except that the deposit copies need not be manufactured within the United States, thus giving the author the exclusive right of translation. Copies published for use in America must of course bear the copyright notice. A translation into English from such text cannot be copyrighted unless the deposit copies of the English translation are manufactured within the United States; and this holds true also in respect to translations into a language other than English, as it is only "the original text" which can be copyrighted without American manufacture. {Sidenote: Ad interim deposit} In respect to books published abroad in the English language, _ad interim_ protection is assured by the provision (sec. 21): "That in the case of a book published abroad in the English language before publication in this country, the deposit in the Copyright Office, not later than thirty days after its publication abroad, of one complete copy of the foreign edition, with a request for the reservation of the copyright and a statement of the name and nationality of the author and of the copyright proprietor and of the date of publication of the said book, shall secure to the author or proprietor an _ad interim_ copyright, which shall have all the force and effect given to copyright by this Act, and shall endure until the expiration of thirty days after such deposit in the Copyright Office." {Sidenote: Completion of ad interim copyright} On such works the provisional copyright is made permanent under the provision (sec. 22): "That whenever within the period of such _ad interim_ protection an authorized edition of such book shall be published within the United States, in accordance with the manufacturing provisions specified in section fifteen of this Act, and whenever the provisions of this Act as to deposit of copies, registration, filing of affidavit, and the printing of the copyright notice shall have been duly complied with, the copyright shall be extended to endure in such book for the full term elsewhere provided in this Act."
