Title

¬The hidden classification in Library of Congress Subject Headings for Judaica

Abstract

The syndetic structure of subject headings lists, in particular the broader/narrower term references, constitutes a hidden classification that may be converted to an explicit tree structure. Such a structure may be used to examine the hierarchy of LC subject headings (LCSH) and to compare them with that of Library of Congress Classification (LCC). Joseph Galron's compilation, 'Library of Congress Subject Headings in Jewish Studies (1991)', was analyzed for several features relating to the hierarchy of terms, and trees tructures were built for the deepest hierarchies: Jews, Judaism, Hebrew language, and Israel. These were compared with the corresponding LC classes. A hierarchy in LCSH may have more levels than the corresponding schedule in LCC. It is concluded that the conversion of the BT / NT references of subject headings lists into tree structures is a useful tool for examining the correctness of a hierarchy. Display of subject headings in tree-structure format can assist users in grasping the hierarchy of subject headings and in navigating online catalogs
