- Abstract
- Subject retrieval by Library of Congress (LC) Classification numbers is examined from the perspective of 5 user groups of on-line catalogues. Although, at present, librarians are the user group most likely to benefit from the LC classification advances in the capabilities of on-line catalogues. Research on the use of the LC classification schedules as a component of subject retrieval should continue.
