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 growing number and sophistication of online bibliographic and networked based information systems is starting to blur the once clear boundaries that separated print documents. 2 concepts emerge as a consequence of these developments, first the 'union record', an entity which combines multiple catalog records for a single bibliographic item into an extended information object; and 2nd, an information 'dossier', a hypertext-like information object built by linking several distinct but related bibliographic entites
