_b._ Deposit copies: one copy of the best edition at the British Museum, and four copies of the usual edition at Stationers' Hall for distribution to the Bodleian Library at Oxford, the University Library at Cambridge, the Faculty of Advocates Library at Edinburgh, and the Trinity College Library at Dublin. _c._ Register title of book and day of first publication at Stationers' Hall, London. 7. _The United States Copyright Office._ One frequently hears the expressions "has obtained a copyright," "issued a copyright," etc., giving the impression that copyrights can be granted somewhat after the manner in which the Patent Office issues letters-patent. But Congress has established no office authorized to furnish any such guarantee of _literary_ property as is done in the case of patent monopoly. The Copyright Office is purely an office of record and simply registers _claims_ to copyright. The form of record prescribed by law being the effect that A. B. "hath deposited the title of a book the right whereof he _claims_ as author or proprietor in conformity with the laws of the United States respecting copyrights." The Copyright Office has no authority to question any claim as to authorship or proprietorship, nor can it determine between conflicting claims. It registers the claim presented in the prescribed form for a proper subject of copyright by any person legally entitled to such registration without investigation as to the truthfulness of the representations, and would be obliged to record, not only the same title for different books, but the same title for the same work on behalf of two or more different persons, even against the protest of either one, were such registrations asked for. No examination is therefore made when a title reaches the office as to whether the same or a similar title has been used before. As I have already stated, the title _per se_ is not subject to copyright, and no one can secure a monopoly of the use of a title by merely having it recorded at a nominal fee at the Copyright Office.
