Abstract

Indexing consistency between Library of Congress and British Library catalogers using the LCSH is compared.82 titles published in 1987 in the field of library and information science were identified for comparison, and for each title its LC subject headings, assigned by both LC and BL catalogers, were compared. By applying Hooper's 'consistency of a pair' equation, the average indexing consistency value was calculated for the 82 titles. The average indexing value between LC and BL catalogers is 16% for exact matches, and 36% for partial matches
