- Abstract
- Describes the role of the Library of Congress (LoC) in leading cooperative initiatives to overcome the crisis in cataloguing borught about by cuts in cataloguing departments. With the aim of making bibliographic control better, faster, and cheaper the LoC invited experts to discussions from which emerged the Program for Cooperative Cataloging (PCC). Officially established in 1995, the PCC is a coalition of libraries working to increase the availability of unique records created to agreed standards. Membership now exceeds 200. Participants can join programmes for name and series authorities, subject-headings-classification proposals and contribute bibliographic records to BIBCO. Explains the democratic structure of the coalition and assesses the achievements of the LoC and PCC in pursuit of the various goals. Reviews the accomplishment of the Cooperative Online Serials Program and international ventures, involving Canada, UK, Australia and New Zealand and lists the benefits of participation in cooperative endeavours

- 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
- The network structure of a hyperlinked environment can be a rich source of information about the content of the environment, provided we have effective means for understanding it. We develop a set of algorithmic tools for extracting information from the link structures of such environments, and report on experiments that demonstrate their effectiveness in a variety of contexts on the World Wide Web. The central issue we address within our framework is the distillation of broad search topics, through the discovery of "authoritative" information sources on such topics. We propose and test an algorithmic formulation of the notion of authority, based on the relationship between a set of relevant authoritative pages and the set of "hub pages" that join them together in the link structure. Our formulation has connections to the eigenvectors of certain matrices associated with the link graph; these connections in turn motivate additional heuristics for link-based analysis.

- 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.

- Abstract
- The use of diagrams to express relationships in classification is not new. Many classificationists have used this approach, but usually in a minor display to make a point or for part of a difficult relational situation. Ranganathan, for example, used diagrams for some of his more elusive concepts. The thesaurus in particular and subject headings in general, with direct and indirect crossreferences or equivalents, need many more diagrams than normally are included to make relationships and even semantics clear. A picture very often is worth a thousand words. Rolling has used directed graphs (arrowgraphs) to join terms as a practical method for rendering relationships between indexing terms lucid. He has succeeded very weIl in this endeavor. Four diagrams in this selection are all that one needs to explain how to employ the system; from initial listing to completed arrowgraph. The samples of his work include illustration of off-page connectors between arrowgraphs. The great advantage to using diagrams like this is that they present relations between individual terms in a format that is easy to comprehend. But of even greater value is the fact that one can use his arrowgraphs as schematics for making three-dimensional wire-and-ball models, in which the relationships may be seen even more clearly. In fact, errors or gaps in relations are much easier to find with this methodology. One also can get across the notion of the threedimensionality of classification systems with such models. Pettee's "hand reaching up and over" (q.v.) is not a figment of the imagination. While the actual hand is a wire or stick, the concept visualized is helpful in illuminating the three-dimensional figure that is latent in all systems that have cross-references or "broader," "narrower," or, especially, "related" terms. Classification schedules, being hemmed in by the dimensions of the printed page, also benefit from such physical illustrations. Rolling, an engineer by conviction, was the developer of information systems for the Cobalt Institute, the European Atomic Energy Community, and European Coal and Steel Community. He also developed and promoted computer-aided translation at the Commission of the European Communities in Luxembourg. One of his objectives has always been to increase the efficiency of mono- and multilingual thesauri for use in multinational information systems.

- Abstract
- Many information portals are adding social features with hopes of enhancing the overall user experience. Invitations to join and welcome pages that highlight these social features are expected to encourage use and participation. While this approach is widespread and seems plausible, the effect of providing and highlighting social features remains to be tested. We studied the effects of emphasizing social features on users' response to invitations, their decisions to join, their willingness to provide profile information, and their engagement with the portal's social features. The results of a quasi-experiment found no significant effect of social emphasis in invitations on receivers' responsiveness. However, users receiving invitations highlighting social benefits were less likely to join the portal and provide profile information. Social emphasis in the initial welcome page for the site also was found to have a significant effect on whether individuals joined the portal, how much profile information they provided and shared, and how much they engaged with social features on the site. Unexpectedly, users who were welcomed in a social manner were less likely to join and provided less profile information; they also were less likely to engage with social features of the portal. This suggests that even in online contexts where social activity is an increasingly common feature, highlighting the presence of social features may not always be the optimal presentation strategy.

- Abstract
- Reports on the experimental test of several causes of user errors while composing database queries. The query language under consideration is SQL. A query writing model was developed that integrated a GOMS type analysis of query writing with the characterisitcs of human cognition. This model revealed multiple cognitive causes of a frequent and troublesome error, join clause omission. This semantic user error returns answers from the database that may undetectably wrong, affecting users, decision makers, and programmers. The model predicted 4 possible causes of join clause omission, and empirical testing revealed that all 4 contributed to the error. Gives reasons why the frequency of this error increased. These results are significant for understanding user errors in general and for the developing new interfaces and training schemes for the task of writing database queries

- 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
