Abstract

The chapter on indexes in The Chicago Manual of Style serves as a standard for index format and as a self teaching tool for authors and novice indexers. Reviews the 14th ed. for logical sequence, accordance of the guidelines and rules with those of other manuals and authorities, and the quality of its index. It is found wanting in all these areas, but contains much useful information on the indexing process and book index format

Abstract

The invention of the citation index was credited to Shepard (1873) and Shapiro described a legal citation index published in 1743. A similar index was embedded in the Talmud 2 centuries earlier (1546). The 1st Hebrew citation index to a printed book is dated 1511. The earliest Hebrew manuscript citation index, ascribed to Maimonides, dates from the 12th century. Considerable knowledge was assumed for users of these tools. The substantial knowledge of their compilers contrats with the semi-automatic production of modern citation indexes. The terms citation, quotation, reference, cross-reference, locator, and concordance are employed inconsistently in publications about Hebrew indexes. There is a lack of citation links between the secondary literature on Hebrew indexes and that of citation analysis

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 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

Thesauri-structured controlled vocabularies, designed for information retrieval-are compared with classification schemes developed for the arrangement of library materials and/or bibliographic records. The syndetic structure (BTs and NTs) within the alphabetic sequence of thesauri constitutes a hidden classification, but many thesauri include an explicit hierarchical display; some feature notation. The various structures and applications of thesauri are surveyed, with an emphasis on their increasing role in electronic information retrieval. The skills required for thesaurus construction are similar to those for the development of classification schemes. The distinction between these activities is expected to blur in the future.
