The application is in general in simple form, and care should be taken in filling out the card that the space at the top intended for use by the Copyright Office should be left blank. The application must be signed with the name and address of the copyright claimant, who may be the author or his representative, as where his publisher is taking out the copyright. In the case of works made for hire, the employer may make application as author. The name of the author should be given on the line provided for that purpose, even though the name of the author as claimant is also given above; but in the case of anonymous or pseudonymous works, the name of the author is not required. The title should be given exactly as on the title-page of the book or on the work, and the other particulars called for in the application should be exactly as indicated by the work itself. The day of publication must be exactly stated, and the application cannot be made, therefore, until _after_ publication. Provision is also made on the card for the name and address of the person to whom the certificate of registration is to be sent and of the remitter of the fee, and in the case of books, the application must be accompanied by the affidavit made either on the reverse of the application card or on the separate card also provided. In applications, as for foreign or _ad interim_ copyright, where the nationality of the author should be stated, information as to citizenship, not race, is required. A person naturalized in the United States is defined as an American. A foreign author claiming copyright because of residence, must state that he is a "permanent resident" of the United States (C. O. Rule 29). {Sidenote: Illustrations} The illustrations of a book may be separately registered, and if by lithographic or photo-engraving process must also have affidavit of manufacture in this country. Maps and charts are classed with works of art, and the formalities in respect to these, as well as in respect to dramatic and musical compositions, are treated specifically in the chapters on those specific subjects. {Sidenote: Periodicals} In respect to periodicals, application should be made as for books, but no affidavit is required; separate registration is necessary for each number published, with notice of copyright, and can be made only after publication. It is not possible to register the title of the periodical in advance of publication. (C. O. Rule 36.) Two deposit copies of periodicals are required; but a contribution to a periodical separately registered requires the deposit of only one copy of the periodical. The entire copy should be sent, as a mere clipping does not comply with the statute. (C. O. Rule 37.) The date of publication of a periodical is not necessarily the printed date of issue, and the actual day of publication should be stated in the application, whether for the registration of the periodical itself or a contribution to it.
