Abstract

Indexes in general seek to provide a "key" to a body of literature intending to help the user in identifying, verifying, and/or locating individual or related items. The most common devices for collocation in indexes are authors' names and subjects. A different approach to collocating related items in an index is provided by a method called "citation indexing." Citation indexes attempt to link items through citations or references, in other works, by bringing together items cited in a particular work and the works citing a particular item. Citation indexing is based an the concept that there is a significant intellectual link between a document and each bibliographic item cited in it and that this link is useful to the scholar because an author's references to earlier writings identify relevant information to the subject of his current work. One of the major differences between the citation index and the traditional subject index is that the former, while listing current literature, also provides a retrospec tive view of past literature. While each issue of a traditional index is normally concerned only with the current literature, the citation index brings back retrospective literature in the form of cited references, thereby linking current scholarly works with earlier works. The advantages of the citation index have been considered to be its value as a tool for tracing the history of ideas or discoveries, for associating ideas between current and past work, and for evaluating works of individual authors or library collections. The concept of citation indexing is not new. It has been applied to legal literature since 1873 in a legal reference tool called Shepard's Citations. In the 1950s Eugene Garfield, a documentation consultant and founder and President of the Institute for Scientific Information (Philadelphia), developed the technique of citation indexing for scientific literature. This new application was facilitated by the availability of computer technology, resulting in a series of services: Science Citation Index (1955- ), Social Sciences Citation Index (1966- ), and the Arts & Humanities Index (1976- ). All three appear in printed versions and as machine-readable databases. In the following essay, the first in a series of articles and books elucidating the citation indexing system, Garfield traces the origin and beginning of this idea, its advantages, and the methods of preparing such indexes.

Abstract

The Colon Classification has not been widely adopted; however, the theory of facet analysis and synthesis Ranganathan developed has proved to be most influential. Although many theorists of subject analysis do not totally agree with his fundamental categories or citation order, Ranganathan's concept of facet analysis and synthesis has provided a viable method and a framework for approaching subject analysis and has become the foundation of subject analysis in the twentieth century. In this sense, his theory laid the groundwork for later investigations and inquiries into the nature of subject and classificatory categories and citation order. His influence is felt in all modern classification schemes and indexing systems. This is attested to by the citations to his ideas and works in numerous papers included in this collection and by the fact that other modern classification systems such as the Dewey Decimal Classification and the Bliss Bibliographic Classification have become increasingly faceted in recent editions. The following chapter from Elements of Library Classification represents one of Ranganathan's many expositions of facet analysis and fundamental categories. It is chosen because of its clarity of expression and comprehensibility (many readers find the majority of his writings difficult to understand).
