Comparison of Association Between LC Subject Headings And Class Notations in Single- and Multiple-Heading Records
Khosh-khui, Sam Abolghasem
Subject headings and their corresponding class notations of 101,347 of the Library of Congress MARC records were analysed to determine variations in the association between Library of Congress Subject Headings (LCSHs) and Library of Congress Classification Notations (LCCNs) with respect to the variations in the number of subject headings per record. As the number of LCSHs per record increased, the association between LCSHs and LCCNs decreased. The probability of having identical LCCNs for identical LCSHs in single-heading records was found to be significantly higher than in multiple heading records. This implies that in recommending a class notation to a patron, distinction should be made between single- and multiple heading bibliographic records.
