Abstract

Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities
