Abstract

One of the earliest works on the theory of classification appeared in a series of six chapters an the "Principles of Book Classification" published between October 1911 and May 1912 in the Library Association Record. In this publication, the author, E. Wyndham Hulme (1859-1954) whose career included twenty-five years as Librarian of the British Patent Office, set forth the fundamentals of classification as manifested in both the classed and the alphabetical catalogs. The work and the ideas contained therein have largely been forgotten. However, one phrase stands out and has been used frequently in the discussions of classification and indexing, particularly in reference to systems such as Library of Congress Classification, Dewey Decimal Classification, and Library of Congress Subject Headings. That phrase is "literary warrant"-meaning that the basis for classification is to be found in the actual published literature rather than abstract philosophical ideas or concepts in the universe of knowledge or the "order of nature and system of the sciences." To the extent that classification and indexing systems should be based upon existing literature rather than the universe of human knowledge, the concept of "literary warrant" defines systems used in library and information services, as distinguished from a purely philosophical classification. Library classification attempts to classify library materials-the records of knowledge-rather than knowledge itself; the establishment of a class or a heading for a subject is based an existing literature treating that subject. The following excerpt contains Hulme's definition of "literary warrant." Hulme first rejects the notion of using "the nature of the subject matter to be divided" as the basis for establishing headings, then he proceeds to propose the use of "literary warrant," that is, "an accurate survey and measurement of classes in literature," as the determinant.
