The definition of the date of publication (sec. 62) as "the earliest date when copies of the first authorized edition were placed on sale, sold, or publicly distributed by the proprietor of the copyright or under his authority" remedies the vagueness of the previous law and adopts into the statute court decisions to the effect that acts not by the authority of the author or proprietor do not constitute publication in the sense of dedication to the public. In other words, it is made clear that the right to publish inheres in the author and that he cannot be divested of it without his consent. This is the fundamental principle of the new law in the vital matter of protecting the author at the critical point at which an unpublished work, absolutely his own, becomes a published work, subject to statute. In this respect the American code of 1909 comes very close to the acceptance of the right in intellectual property as a natural and inherent right. {Sidenote: What constitutes publishing} As to what constitutes publishing, interpretation by the courts based on previous law will in many respects be applicable to the new code. A book which has been sold or leased to subscribers on a contract of restricted use is none the less published, as was set forth in the opinion by Chief Judge Parker of the N. Y. Court of Appeals in Jewellers' Mercantile Agency _v._ Jewellers' Weekly Pub. Co. in 1898, and in the opinion by Judge Putnam of the U. S. Circuit Court in Massachusetts in Ladd _v._ Oxnard in 1896, both having reference to credit-rating books leased to subscribers for their individual use. {Sidenote: "Privately printed" works} Publication depends upon sale or offer to the public, and it is a question whether the sale or offer of a copyrightable work, as the proceedings or publications of a society, to the members of that society only, constitutes publication, to be passed upon by the courts in view of the specific facts. A work "privately printed" or with the imprint "printed but not published," given or even sold by the author to his friends, and not sold generally by his authority, would probably not be held to be published; but the courts would probably hold that the sale of a work, though "privately printed," to merely nominal members of a nominal society, made up of the purchasers of the work, would constitute publication and, if without copyright notice, dedication. {Sidenote: Copying}
