Abstract

Brian C. Vickery, Director and Professor, School of Library, Archive and Information Studies, University College, London, is a prolific writer on classification and information retrieval. This paper was one of the earliest to present initial efforts by the Classification Research Group (q.v.). In it he clearly outlined the need for classification in subject indexing, which, at the time he wrote, was not a commonplace understanding. In fact, some indexing systems were made in the first place specifically to avoid general classification systems which were out of date in all fast-moving disciplines, especially in the "hard" sciences. Vickery picked up Julia Pettee's work (q.v.) an the concealed classification in subject headings (1947) and added to it, mainly adopting concepts from the work of S. R. Ranganathan (q.v.). He had already published a paper an notation in classification, pointing out connections between notation, words, and the concepts which they represent. He was especially concerned about the structure of notational symbols as such symbols represented relationships among subjects. Vickery also emphasized that index terms cover all aspects of a subject so that, in addition to having a basis in classification, the ideal index system should also have standardized nomenclature, as weIl as show evidence of a systematic classing of elementary terms. The necessary linkage between system and terms should be one of a number of methods, notably:
- adding a relational term ("operator") to identify and join terms; - indicating grammatical case with terms where this would help clarify relationships; and - analyzing elementary terms to reveal fundamental categories where needed. He further added that a standard order for showing relational factors was highly desirable. Eventually, some years later, he was able to suggest such an order. This was accepted by his peers in the Classification Research Group, and utilized by Derek Austin in PRECIS (q.v.). Vickery began where Farradane began - with perception (a sound base according to current cognitive psychology). From this came further recognition of properties, parts, constituents, organs, effects, reactions, operations (physical and mental), added to the original "identity," "difference," "class membership," and "species." By defining categories more carefully, Vickery arrived at six (in addition to space (geographic) and time): - personality, thing, substance (e.g., dog, bicycle, rose) - part (e.g., paw, wheel, leaf) - substance (e.g., copper, water, butter) - action (e.g., scattering) - property (e.g., length, velocity) - operation (e.g., analysis, measurement) Thus, as early as 1953, the foundations were already laid for research that ultimately produced very sophisticated systems, such as PRECIS.
