Abstract:
This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and
literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval,
and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications,
which broadly are subject collocation and facilitation of browsing the collection. It explains with details the com ponents of a library classification system and their functions. The major components are schedules, notations, and
index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices
for number synthesis which are not required in a knowledge classification. It illustrates with examples from the
WebDewey good examples of added features of an online library classification system. It emphasizes that institu tional backup and a revision machinery are essential for a classification to survive and remain relevant in the print
and e-environment
