Abstract

Julia Pettee's contribution to classification theory came about as part of her work an subject headings. Pettee (1872-1967) was for many years librarian of the Union Theological Seminary in New York and was best known for the classification system she developed for the seminary and as the author of the book Subiect Headings. She was one of the first to call attention to the fact that there was a classification system in subject headings. It was, as she put it, "completely concealed when scattered through the alphabetical sequence" (p. 98). On the other hand, she recognized that an index entry was a pointing device and existed to show users specific terms. Index terms, unlike subject headings, could be manipulated, inverted, repeated, and stated in as many words as might be desired. The subject heading, she reiterated, had in it "some idea of classification," but was designed to pull together like material and, unlike the index term, would have limited capability for supplying access by way of synonyms, catchwords, or other associative forms. It is interesting that she also thought of the subject heading in context as forming a three-dimensional system. Logically this is the case whenever one attempts to reach beyond the conventional hierarchy as described an a plane surface, and, in fact, thought out as if the classification were an a plane surface. Pettee described this dimension variously as names "reaching up and over the surface ... hands clasp[ing] in the air" from an individual term (pp. 99-100). Or, in other context, as the mapping of "the many third-dimensional criss-crossing relationships of subject headings." (p. 103) Investigations following Pettee's insight have shown the nature and the degree of the classification latent in subject headings and also in the cross-references of all indexing systems using cross-references of the associative type ("see also" or equivalent terminology). More importantly, study of this type of connection has revealed jumps in logic and meaning caused by homographs or homonyms and resulting in false connections in classification. Standardized rules for making thesauri have prevented some of the more glaring non sequiturs, but much more still needs to be done. The whole area of "related terms", for example, needs to be brought under control, especially in terms of classification mapping.

Abstract

In the early 20th century, Paul Otlet carved out a role for bibliography and documentation as a force for positive social change. While his ideals appeared to be utopian to many of his contemporaries, his activism and vision foreshadowed the potential of the World Wide Web. This paper discusses the role that KO professionals could play in enhancing the positive social impact of the web of knowledge, and how our roles are shifting from the more passive role of descriptive cataloguers, to proactive designers of positive and productive knowledge environments.
