Mr. Justice Holmes

delivered the opinion of the court.

This is a suit brought by the appellee, to restrain the infringement of copyright in a book entitled “Webster’s High School Dictionary.” The appellee, a Massachusetts corporation, took out copyrights at the same time in England and here. It published and sold the book in this country with the statutory notice of copyright, and made a contract with English publishers, under which it furnjshed them with electrotype plates of the work, and they published it in England, omitting notice of .the American copyright. The English work has a different title, .“Webster’s Brief International' Dictionary,” and has some other differences on the first , three and last thirty-four pages, but otherwise is the same. The appellant, an Illinois corporation, sent for the English book with intent to reprint it, and was about to publish it when restrained. The English publishers agreed not to import any copies of their work into this country, and also to use all reasonable means to-prevent an importation by others, so that the appellee cannot be said to have assented to the appellant’s act. So far as appears, the only copies that have been brought over are the one above mentioned and another, purchased for use but not for sale, by the president and manager of the appellant. The question is whether the omission of notice of the American copyright from the English publication, with the assent of the appellee,, destroyed its rights, or, in other words, ■whether the requirement of the act of June 18, 1874, c. 301, § 1, 18 Stat. 78 (Rev. Stat. §4962), that notice shall be in *264 sérted “in the several copies of every edition published” extends to publications abroad. The Circuit Court sustained the defendant’s contention and dismissed the bill. 140 Fed. Rep. 768. The Circuit Court of Appeals reversed this decision, 146 Fed. Rep. -354; S. C., 76 C. C. A. 470, and the case, is brought to this cóurt by appeal.

■ Notwithstanding the elaborateness of ,the arguments addressed tó ús and the. difference of opinion in the courts below, there is not a great deal to be said, and the answer seems to us plain. Of course, Congress could attach what conditions it-saw fit to i.ts grant, but it is'Unlikely that it would make requirements-of personal action beyond the sphere of its control. Especially is it unlikely that it would require a warning- to the public against the infraction of a law beyond the jurisdiction .where that law Was in force. The reasons for doing so have not grown less, yet in the late statute giving' copyright for foreign publications the notice is necessary only iii “¿11 copies of such books sold or distributed in the United States.” Act of March 3, 1905, c. 1432, 33 Stat. 1000, amending Rev. Stati § 4952.- So it is decided that the section punishing a false notice, which naturally would be coextensive with the requirement of notice, did not extend to false' statements affixed abroad. McLoughlin v. Raphael Tuck Co., 191 U. S. 267. The same conclusion would follow from the form prescribed for' the notice, which would be inapt in -foreign lands.

It is said that the act of 1905 cannot affect the construction of the law under which the parties’ rights .were fixed, ¿nd it cannot, beyond illustrating a policy that has not changed. But the age of the condition affords another reason'for confining it as the later condition is confined. ' When it first was attached, in 1802,' there was little ground to anticipate • the publication of American works abroad,. As, late as 1820 Sydney Smith, in the Edinburgh Review, made hia famous exclamation, “ In the four quarters of .the globe, who reads an American book?” If, however, there was a publication abróad, importation without the consent of the owner was *265 forbidden in general terms, a fact giving another reason for the narrower construction of § 4962. If that was the. true construction once, it is the construction still. Again, when the present act was passed, there was no foreign copyright for an American author, and Congress knew and he knew, as he knows now, if he contents himself with home protection, that his work might be reprinted without notice of any sort. Such reprints rather inconsistently are called piracies in argument.. But whatever the moral aspects may be, the piracy is a legal right, and as such its- exercise must be contemplated by the author. It does not matter whether he does so with regret at the loss of money or with joy at the prospect of fame, and it is difficult to see any greater difference between giving consent to the foreign publication and intentionally creating the opportunity, the inducement and the right. But it hardly would be argued that because no copyright had been taken out in - England and therefore the reprint there was lawful, an American copyright, could be defeated by importing the English book and reprinting from that. Thompson v. Hubbard, 131 U. S. 123, 150. It would be even bolder to say that the American author would have stood worse if in the days before he could get a copyright in England he had made an arrange,ment with English-publishers to secure some payment from them. Yet that is the logic of the appellant’s case.

If a publication without notice of an American copyright did not affect the copyright before the days when it was possible to get an English copyright also, it is not to be supposed that Congress, by arranging with England for that possibility, gave a new meaning to the old § 4962, increasing the burden of American authors, and attempted to intrude its requirements into any .notice that might be provided by the English law. The words of the section remained unchanged, notwithstanding the gfant of a limited liberty of importation, while other sections were amended where there was reason for a change.

It may be that in most cases the importation of a pirated English copy óf an American book would be unlawful, whereas *266 it is. argued that the importation was lawful in the case at bar. .The appellee makes a strong argument that the appellant’s importation was wrong. But it is hard to see how the right to copy a book, whether lawfully or unlawfully imported, can be affected by the mode in which it got here. The analogies of the law are the. other way. A person is subject to the jurisdiction, even if he was brought there by wrong. Pettibone v. Nichols, 203 U. S. 192. A document is admissible in-evidence, although it was impfoperly obtained. Commonwealth v. Tucker, 189 Massachusetts, 457, 470; 3 Wigmore, Evidence, §2183. The argument for the appellant dwells somewhat fancifully on the possibilities of innocence being led astray. All those possibilities, might exist if a pirated volume should be smuggled into the United States. Moreover the appellant argues, with the support of the opinion of an Attorney General and a Solicitor General,, that under § 4956 and its amendments tWo copies of an unauthorized edition lawfully might be imported for use. 21 Op. Atty.- Gen. 159, 162. The statutes cannot be expected to do more than to' secure the author and the . public só far as. is reasonably practicable. The obvious plan is not to'be distorted- by the chance that-ingenuity may find .-some way to slip through-the law uncaught.

■ A¿ we are-satisfied that the statute does not require notice of the American copyright' bn books published abroad and sold -only for use there, we agree with the parties that it is unnecessary to discuss nice questions as to when a foreign reprint may ,or may not be imported.into the United States under the present provisions- of our law.

Decree affirmed.
