Designed for use in school libraries, this manual outlines simplified procedures for cataloging, defined as the indexing of an item; for classification, defined as the assignment of a subject number to the item; and for processsing, defined as the preparation of the item so that it can be borrowed from the library. The manual is divided into 10 sections covering: (1) systems of library organization, including standard and non-standard systems, and the use of original or commercial cataloging; (2) preliminary steps in organizing a library; (3) steps in cataloging and classification, including bibliographic and physical descriptions of an item; (4) classification of books for the primary grades, fiction, nonfiction, biographies, and reference books; (5) assignment of subject headings for biographies, fiction, and books for the primary grades; (6) assignment of other index terms; (7) cataloging and classification of audiovisual materials; (8) typing of catalog cards; (9) filing of catalog cards; and (10) processing of books and audiovisual materials. Sample T-slips or preliminary typing slips, catalog cards, book pockets, and book cards are illustrated throughout the manual. (Author/ESR)
