A citation index is an a posteriori one in which the user is referred to more recent citations from the older ones. In the field of law the method was originated by shepard in 1873. Eugene garfield has more recently applied the method to his science citation index first published in 1963. Proponents of citation indexing claim that the method avoids the most vexing probelms of subject indexing rapidly changing terminology, illogical categories, and nonspecificity. Several research studies on citation indexing are currently in progress, and authors point to other areas requiring investigation. Citation indexing must demonstrably be doing something which conventional indexing does not do. One of the most important problems is unspecified citations. As each author is virtually his own indexer the citations he lists in his bibliography must be assumed to be valuable, but some of the citations may refer to procedures or statistical processes having little connection with the purpose of his paper, exclusion may be the result of editorial policy. We need a degree of correlation between the citations used and the subject in question. Further investigation is needed also into non citation and the absence of bibliographies to articles, and their effects on the utility of citation indexes. Would wider coverage result in a more efficient index? is the book format of citation indexes a limiting factor? [ABSTRACT FROM AUTHOR] |
