Abstract
Subject headings in 7834 LC monographic MARC records were analyzed to determine relationship between the specificity of LC Subject Headings and the number of subject headings per bibliographic record. The findings indicated that a weak inverse correlation existed between thc specificity of LC Subject Headings and the number of subject headings assigned to each document. The study concluded that using more specific subject headings does not reduce the mean of headings per bibliographic record. The number of headings assigned to each document most likely depends on the variation of topics discussed in a document, the availability of specific headings to cover multiple topics, and local management policy.
