Whether simple quotation constitutes an infringement or is "fair use," depends upon extent and in some respects upon purpose. In 1892 Justice North, in the English Court of Chancery, in Walter _v._ Steinkopff, held that the use by the _St. James Gazette_ of two fifths of an article by Kipling, copyrighted by the _Times_, was beyond "fair use" of quotations, notwithstanding the newspaper custom of copying from one another. On the other hand, quotations in a review of a book made to reasonable extent for the purposes of criticism, have usually been considered "fair use," provided they do not go to the extent of a description or abridgment which would be measurably a substitute for the book. {Sidenote: Private use} The multiplication of copies by handwriting or other process for private use, as among the members of an orchestra or in a business office, has been held an infringement in English decisions, though prohibition of the making of a single copy for personal use would be an extreme application of this doctrine, and such use is specifically permitted in the new English code. {Sidenote: The doctrine of "unfair competition"} Beyond the purview of copyright law, there is a means of legal remedy for the copyright proprietor which can be enforced by state as well as by federal courts, resting either upon statutes outside the copyright law, or on the general principles of equity. This is the application of the doctrine of "unfair competition" especially in cases involving "fraud" or fraudulent representation, direct or implied, leading the purchaser to buy something other than what he supposes he is buying. Thus if a publisher prints and binds a book with a title and in a style that leads a purchaser to suppose that it is another book which he is buying, the publisher of the other book has the right to obtain equitable relief by an injunction from the transgressor on the ground of unfair competition without any reference to copyright law, although this doctrine is more applied in the case of patents, trade-marks and copyrights than perhaps any other field. {Sidenote: The doctrine of deceptive intent} There is also evident a growing tendency on the part of the courts to protect the public from possible deception especially if done with fraudulent intent, where some distinctive name or symbol or form associated with some line of product is used for another line of product of different origin and character, though there may be here no direct competition; but this comparatively new doctrine is more likely to be used in regard to trade-mark articles than in respect to literary and like property. It might, however, apply in a case where a well-known publishing house had published, for instance, a popular series of school books as Smith's Arithmetical Readers and another firm containing the same name had started to publish a Smith's Algebraic Readers--but the application would be extremely doubtful. {Sidenote: The "Chatterbox" cases}
