- 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
- Documents in digital and paper libraries may be arranged, based on their topics, in order to facilitate browsing. It may seem intuitively obvious that ordering documents by their subject should improve browsing performance; the results presented in this article suggest that ordering library materials by their Gray code values and through using links consistent with the small world model of document relationships is consistent with improving browsing performance. Below, library circulation data, including ordering with Library of Congress Classification numbers and Library of Congress Subject Headings, are used to provide information useful in generating user-centered document arrangements, as well as user-independent arrangements. Documents may be linearly arranged so they can be placed in a line by topic, such as on a library shelf, or in a list on a computer display. Crossover links, jumps between a document and another document to which it is not adjacent, can be used in library databases to allow additional paths that one might take when browsing. The improvement that is obtained with different combinations of document orderings and different crossovers is examined and applications suggested.

- Abstract
- The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

- Abstract
- Hypertext users often experience the so called 'lost in hyperspace' problem: where users experience disorientation stemming from too many jumps in the course of browsing through large databases. Proposes a filtering algorithm which is suitable for a wide spectrum of implementations and which restricts the amount of information available to the user; thus allowing improved hypertext browsing. An algorithm calculates the set of most relevant hypertext nodes for the user, utilizing the user profile and data clustering technique. The result is an optimal cluster of relevant data items, custom-tailored for each user's needs

- Discussion of the results and consequences of the automation project named thesaurus/concordance project, carried out at the DUT Library. The aim of the project was, by making the subject headings and their corresponding classification codes machine readable, to produce periodically cumulative lists, classifies lists, lists per subject fields, alphabetical lists of inverted subheadings and geographical names with their corresponding main headings and notations

- Abstract
- The history of the Library of Congress Subject Headings is traced, from its beginnings with the implementation of a dictionary catalog at the Library of Congress in 1898 to the present day. The author describes the most significant changes which have occurred in LCSH policies and practices during the 100-year period. Events noted near the end of the century indicate an increased willingness on the part of' the Library of Congress to involve the larger library community in the creation or revision of subject headings and other decision-making regarding the LCSH system. Finally, the author provides a summary of the other contributions to this collection of essays, a collection which celebrates the "centennial" of the world's most popular library subject heading language

- Abstract
- Surveys conducted during the last four years under the auspices of the International Federation of Library Associations and Organizations (IFLA) reveal that the Library of Congress Subject Headings is heavily used in national libraries outside of the United States, particularly in English-speaking countries. Many other countries report using a translation or adaptation of LCSH as their principal subject heading language. Magda Heiner-Freiling presents an analysis of the IFLA data, which also includes information on the classification schemes used by the libraries and whether or not the libraries have produced a manual on the creation and application of subject headings. The paper concludes with an Appendix showing the complete data from the 88 national libraries that respond to the surveys
