Classification and the Specialized Library: Creating a Local Expansion of NLM Classification for Chiropractic Materials

Abstract

Libraries with specialized collections often face unique challenges to providing access to their materials. Cataloging tools, including subject headings and classification systems, are often better suited for less focused collections. Call number classification systems in particular are problematic for libraries with greater depth in certain subject areas. Users expect to be able to walk to the shelf and browse everything about a certain topic in the same section. This is a reasonable request in small libraries, but it is often difficult when working within existing schemas. In response to this problem, the University of Western States Library developed its own expansion to National Library of Medicine Classification in order to better serve its users.
