Abstract

By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis

Abstract

NISO draft standard Z39.50 (sometimes called the "Linked Systems Protocol") provides a standard for linking computers to permit the searching and retrieval of machine-readable bibliographic and authority records. The concept, context, status, and potential of the Linked Systems Protocol are reviewed in relation to the historical development of bibliographies and library catalogs. The functions of a fully developed bibliographic Linked Systems Protocol are summarized and shown to have extensive implications for scholarship, bibliographic access, and the notion of a national database. Effective international use of such a protocol would require the solution of several traditional problems.

Abstract

The author provides an examination of how ideas about place and space have been used in thinking about the organization of knowledge. The spatial analogies of Paul Otlet (1868-1944) in relation to his overall vision are traditional and conventional. Notions of space, place, position, location, and movement are frequent in the work of other leading innovators (Martin Schrettinger, Melvil Dewey, Wilhelm Ostwald, Emanuel Goldberg, and Suzanne Briet) concerning specific practical aspects of knowledge organization. Otlet's spatial imagery is more original and more ingenious when applied to technical problems compared to his overall vision.

Abstract

Librarians have many and varied difficulties. For some library problems research is not the best remedy. Improved coordination, clarification of values, or drawing on existing research results may suffice. When research is indicated, it pays to be selective. Investing in research, like any other kind of investment, should be judged in terms of the probability of success, the likely delay before results are achieved, and the impact on the population of competent researchers, as well as the perceived importance of the problem. New technology permits new forms of service, generates new data for analysis, and supports new tools for researchers. Normal research is repetitious and progresses incrementally. A bolder strategy is to seek significant advances in library service by challenging researchers to achieve a deeper understanding of important, but inadequately understood, library phenomena. Five Grand Challenges are proposed: 1. Library service: Could library services be made more meaningful? 2. Library theory: Who knew what when? 3. Library design: Have digital libraries been designed backwards? 4. Library values: How neutral can libraries be? and 5. Library communities: How do communities differ?
