Yale Law Library Classification

"This classification is designed solely to serve the purposes of the Yale Law School and its Library. It is published primarily for the use of the Yale Law Library staff now and in the future. In its preparation no thought was given to the question whether or not it might be adopted by other libraries. (...) The basis of procedure was that the classification should serve the Library, rather than that the Library should be bound by a preconceived theoretical classification. Although it does in fact in most instances facilitate access to the shelves by readers working as lawyers are accustomed to work, it does not purport to bring all material on a given subject together. This seemed to be neither possible nor desirable, and therefore emphasis has from the outset been laid on the subject side of the card catalogue to which one must, in any library, refer in order to find all material in the library on a given subject."
