- Abstract
- This article discusses the inadequate period divisions of Chinese history in LCSH and LCC. By studying cataloging and classification of Chinese history, the author also reveals the problems of expansion and revision of LCSH and LCC and of the lack of correspondence between LCSH and LCC.

- Abstract
- Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

- Abstract
- The classification work of 26 librarians and 9 students was studied by a thinking aloud method. The structure of their work was analysed into 2 parts that corresond with the stages presented in the ISO standard 5963. Documents were analysed by different concepts of "aboutness". Identification of the principal concepts present in the subject has led into a hypothesis about 3 conceptual systems. Expressing the concepts in terms of classification systems was found to be difficult with UDC because of many unclear synonyms in different parts of the schedules.

- Abstract
- This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

- 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.
