Field for the present treatise In this new stage of copyright development, a comprehensive work on copyright seemed desirable, especially with reference to the new American code. Neither Eaton S. Drone nor George Haven Putnam were disposed to enter upon the task, which has therefore fallen to the present writer. He hopes that his participation for the last twenty-five years in copyright development, — during which, as editor of the Publishers' Weekly and of the Library Journal, he has had occasion to keep watch of copyright progress, and as vice-president of the American (Authors) Copyright League, he has taken part in the copyright conferences and hearings and in the drafting of the new code, — will serve to make the present volume of use to his fellow members of the Authors Club and to like craftsmen, as well as to publishers and others, and aid in clarifying relations and preventing the waste and cost of litigation among the coördinating factors in the making of books and other forms of intellectual property.
Authorities and ackowledgmentsThe present work includes some of the historical material of the Bowker-Solberg volume of 1886, "Copyright, its law and its literature." This material has been verified, extended and brought up to date, especially in the somewhat detailed sketch of the copyright discussions and legislation resulting in the "international copyright amendment" of 1891 and the code of 1909. The volume is in this respect practically, and in other respects entirely new. It has had the advantage of the cordial co-operation of the copyright authorities at Washington, especially the Librarian of Congress, Herbert Putnam, and the Register of Copyrights, Thorvald Solberg; also of helpful courtesy from the Canadian Minister of Agriculture in the recent Laurier administration, Sidney Fisher, and the Canadian Registrar of Copyrights, P.
