Interlibrary loan Involving academic libraries - 1. Book Classification "Every reader hits book." in these words S. R. Rangathan described one of the major functions of libraries: to see that there readers and students are led as directly as possible to the material they need. A number of devices are used for this purpose, one of which is classification. Virtually any gien set of objects may be classified, since to classify is simply to palce together objects having certain characteristics in common, and to seperate them from objects not having those characteristics. Textile fabries, for example, can be classified by material (silk, cotton, wool), or form (knitted, crocheted, woven), or purpose (clothing, carpeting, bedclothing), or even color. Classification of library materials (book, film, sound recordings, and other media) means their arrangement in such a manner as to bring together works dealing with the same subject. A classification scheme, such as the present one, is a listing of subjects coveringthe world of knowledge (or part of it) in some systemic order, together with a notation, or set of symbols, which can be affixed to books for their easy arrangement. Although reader-interest groupings or other homemade arrangements are sometimes used, most librarians have found it preferable to follow one of the major exsisting book classification systems. The principal ones in use in the English-speaking wolrd are the Dewey Decimal Classification and the Library of Congress Classification.the advantages of using one of these are that their notifications are widely known and understood by other librarians and laymen, and that centralized cataloging services such as those library of Congress, the H. W. Wilson Company, and the British National Bibliography'' use one or more of them for classification of specific books, thus making highly professional decisions available to subscribing libraries.
