    Abstract
    The past 100 years have seen the development of numerous systems for the structured representation of knowledge and information, including hierarchical classification systems and with sophisticated features for the representation of term relationships. Discusses reasons for the lack of widespread adoption of these systems, particularly in the USA. The suggested structure for indexing the Internet or other large electronic collections of documents is based on that of book indexes: specific headings with coined modifications

    Abstract
    Postcoordination, in which terms are combined at the searching stage rather than at the time of indexing, has been the main form of database access since the 1950s. Reasons for the failure of postcoordinate searches include the absence of specified relationships between terms, the complexity of formulating Boolean searches, and the high frequency of terms in large databases. Recent writers on indexing electronic text have called for precoordination to enhance the precision of retrieval. Among precoordinate indexing structures, a book index with coined modifications is the most precise. The time and cost associated with such customized analysis will, however, limit its application in the electronic environment

    Abstract
    The history and theory of human textual indexing are surveyed. Basic terms are defined, the extent of the literature is discussed, and key concepts are explained, with an emphasis on thesaurus-based indexing. A section on the consistency of human indexing leads into a discussion of automatic indexing algorithms. An assessment of the future of human indexing concludes the entry. Pages from an early printed index and a manuscript index illustrate the structural elements of index entries as well as features of the format of early indexes that are still found in contemporary publications.

    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
