9.30 Indexes, Definition

An index is a systematic guide to significant items or concepts mentioned or discussed in a work or group of works; the items and concepts are represented by a series of entries arranged in a known or searchable order, with a locator, which is an indication of the place(s) in the work(s) where reference to each item or concept may be found.

9.31 Scope and complexity

An index may be general or specific. A general one lists subjects, authors, persons or corporate bodies, geographical names and other items. A specific index is limited to a particular category of entry, such as one of the items in the above list, abbreviations and acronyms, or citations.

A work may contain a general index and one or more specific indexes. The Dictionary of Canadian Biography, for example, has three: an index of identifications (occupational sectors of those listed), a geographical index and a nominal index. Multiple listings are designed to help readers research a particular aspect of the subject concerned.

The complexity of indexing has fostered the development of a number of computerized indexing methods (see bibliography). Human intervention is nonetheless required for hierarchical arrangement, alphabetization, choice of terms, word order, capitalization and cross-referencing.
