A. Fiction (appended, J. Juvenile books); B. English and American literature; C. History; D. Biography; E. Travels; F. Science; G. Useful arts; H. Fine and recreative arts; I. Political and social science; K. Philosophy and religion; L. Works on language and in foreign languages; R. Reference books.
Numerous sub-divisions would be required to make such a scheme (or indeed any other) fit any collection of books.
In arranging the main classes, care should be taken to bring those most drawn upon near to the delivery desk, or charging system of the library.
The alphabet is usefully applied in the arrangement of several of the great classes of books, and in many sub-divisions of other classes. Thus, all English and American fiction may be arranged in a single alphabet of authors, including English translations of foreign works. All collected works, or polygraphy, may form an alphabet, as well as poetry, dramatic works, collections of letters, and miscellanea, arranged by authors' names. In any of these classes, sub-divisions by languages may be made, if desired.
The class biography may best be arranged in an alphabet of the subjects of the biographies, rather than of writers, for obvious reasons of convenience in finding at once the books about each person.
CHAPTER 22.
Catalogues.
Catalogues of libraries are useful to readers in direct proportion to their fulfilment of three conditions: (1) Quick and ready reference. (2) Arranging all authors' names in an alphabet, followed by titles of their works. (3) Subjects or titles in their alphabetical order in the same alphabet as the authors. This is what is known as a "Dictionary catalogue"; but why is it preferable to any other? Because it answers more questions in less time than any other.
