O N JULY 7, 1961, the Librarian of Congress transmitted to the Speaker of the House of Representatives a report of the questions to be considered and recommendations for their solution in a general revision of the copyright law, Title 17 of the United States Code. Committee on the Judiciary of the House of Representatives issued the report for the purpose of inviting all persons concerned to submit comments and suggestions in order that there might be sufficient careful consideration in the drafting of a copyright law. last general revision of the act was made in 1909. It was the successor of the original copyright act enacted in 1790 by the First Congress of the United States at its Second Session, which had in the intervening one hundred and twenty years been amended and revised in part and subjected to two previous general revisions in 1831 and 1870. original copyright act was passed by Congress pursuant to an authorization contained in the United States Constitution, Article I, Section 8: The Congress shall have Power . .. To Promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.2 In the fifty years since 1909 there have been some amendments in detail covering certain technological advances in the machinery and the devices used in the communicative arts and sciences. Electronics and general technology have had an ever increasing effect upon the fields which the copyright law affects. Commercial radio and television have come into being. Motion pictures and sound recording have advanced. New techniques have been devised for reproducing printed matter and for the manufacture and distribution of instruments for recorded sound. These technological advances have created new fields and a great diversification in the use of the printed word. New industries have sprung up involving copyright so that the copyright office reported that the industries based on copyrighted works accounted for over six billion dollars of our total national income. Of course, the world of books occupies a comparatively small portion of that field, which includes our newspapers, magazines, etc. In the world of books new relationships have sprung up between author and publisher, based in part on the number of subsidiary rights inherent in the book, and new relationships have sprung up between all the industries which utilize the printed word as their basis. In addition, as of September 16, 1955 the United States abides by the Universal Copyright Convention, which is *Copyright Law Revision: Report of the Register of Copyrights on the U.S. Copyright Law.
