R. R. Bowker,
Copyright: Its History and Its Law
“ Copyright is a monopoly to which the government assures protection in granting the copyright. It is a monopoly not in the offensive sense, but in the sense of private and personal ownership; the public is not the loser but is the gainer by the protection and encouragement given to the author. The whole aim of copyright protection is to permit the author to sell as he pleases and to transfer his rights collectively or severally to such assigns as he may choose. Copyright is a monopoly only in the sense that any ownership is a monopoly. ”
