Then, furthermore, with regard to the right respecting perforated rolls, in respect of which I am speaking particularly, I think the right should be entirely distinct and separate from the fundamental copyright, the copyright of the "work," using the term that has been used; that the right to the perforated roll or whatever other form of mechanical reproduction is claimed should be based upon the filing of a copy of that perforated roll; that the filing of the copy of the original work should carry the copyright in the common sense of the word, but if the author desires to claim copyright in a perforated roll on his work, for that purpose, if you please to put it so, he should take it for that purpose, and make his claim of copyright upon that roll. If he wishes it in any other form of reproduction, such as the disk of the talking machine, he should file that; and I think that right should be entirely separate from the right which might pass by an assignment of the copyright. The publisher who may acquire the copyright on the work from the author should not, without express conveyance (although the same person might acquire both) acquire the right to control the perforated roll or the phonograph record or the talking-machine disk; they should be entirely separate. The bill does provide that these shall be regarded as separate estates; but in view of the decisions in which a similar phrase is used, it is clear to me that that means that when the copyright has been obtained by the one proceeding provided for here, all these elements of it are separate estates which might be passed by separate assignments, but they would all be contained in the one copyright. I think that is wrong. I think that the right for the perforated roll should be acquired by filing a copy of that roll, in order that the public may know just exactly what is claimed, and whether it is claimed or not, and whether it is to be utilized. Furthermore, I think that is a right that is naturally distinct from the other. It is a right that goes into manufacture instead of into publication. It is not to be done by the same people, naturally. The manufacturer, having a factory, makes the perforated roll. The publisher makes the books in an entirely different way. The two things are like different lines of trade. They are not naturally blended, either in use or sale. And therefore the composer or author, whichever it be, a work of words or of music, should be entitled to handle it entirely himself, apart from any right that he may have passed to the publisher by the transfer of his copyright.
