There can be no claim to protection for the title of an unpublished book, as a trade-mark or otherwise, just as there can be no copyright in a projected book. This question was elaborately discussed in the leading English case of Maxwell _v._ Hogg, in 1867, in relation to the magazine _Belgravia_, when the rule was laid down that no matter what expenditure had been made or advertising done, a title was not protectable previous to its association with a work actually before the public. Judge Shepley, in 1872, pointed out that "there is no such thing as property in a trade-mark as an abstract name," for a trade-mark simply shows that certain goods "were manufactured by a certain person." Nor can an abandoned title, in the case of a periodical, be held against a person starting a new periodical of that name, providing it does not purport to be a continuation of the old, according to a French case quoted by English authorities. {Sidenote: Projected works not copyrightable} There can be no statutory copyright in a book or other work projected and not yet prepared, despite a very general notion that under the old law a projected book could be protected by registering a title and depositing a title-page of an unwritten or unpublished book. There is nothing in copyright law corresponding to the _caveat_ in patent law. This is not in conflict with the protection of an unpublished work at common law or in equity referred to in the new American code (sec. 2) or the provision in the new law (sec. 11) permitting the registration of "a lecture or similar production or a dramatic or musical composition" or a work of art, before publication, with the deposit of a complete copy or identifying print. {Sidenote: Immoral works}
