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

Three meanings of "information" are distinguished: "information-as-process"; "information-as-knowledge"; and "information-as-thing", the attributive use of "information" to denote things regarded as informative. The nature and characteristics of "information-as-thing" are discussed, using an indirect approach ("What things are informative?"). Varieties of "information-as-thing"include data, text, documents, objects, and events. On this view "information" includes but extends beyond communication. Whatever information storage and retrieval systems store and retrieve is necessarily "information-as-thing"

Abstract

In the past information retrieval has been primarily concerned with text and text-like data. Image-handling is considered as a form of image retrieval and considers the pioneering work of Paul Otlet and Suzanne Briet. Concludes that the terminology of multimedia needs attention to distinguish phenomena, facts, representations, forms of expression, and physical medium

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?
