Abstract

This paper describes the coming together of two independent programmes developing interfaces which improves access to databases. MenUSE - Menu-based User Search Engine - has been developed to search bibliographic databases whilst HIBROWSE - High Resolution Interface for Database Specific BROWsing and SEarching - is a front-end for searching information stored on structured relational database management systems. Combining the 2 approaches affords the user much greater access capabilities than is possible using traditional retrieval systems. The implications of this are explored in the context of EPOQUE (the European Parliament Online QUEry system) and INSPEC

Abstract

This book presents the refereed proceedings of the 9th European Knowledge Acquisition Workshop, EKAW '96, held in Nottingham, UK, in May 1996. The 23 revised full papers included address the most relevant theoretical and applicational aspects of knowledge acquisition with a certain emphasis on the acquisition of knowledge for the modelling or automation of complex problem-solving behaviour. The volume is organized in sections on theoretical and general issues, eliciting knowledge from textual or other sources, data-mining, group elicitation, and planning.

Abstract

"British Librarianship and Information Work 1986-1990" continues a series which has run for more than 60 years. It began, in 1928 as the annual "Year's Work in Librarianship", changed from 1951 to "Five Years' Work in Librarianship" and, with the volume for 1966-1970, took on its present title. The series has established itself as an important record of professional activity and thought, through its comprehensive reviews of most aspects of information and library work. It is valuable to those who wish to keep up to date professionally, noting current developments and trends. It will be equally useful for those researchers and students who in the future need to look back historically on the events and achivements of each quinquennium. This issue follows closely the contents and style of its immediate predecessor "British librarianship and information Work 1981-1985", being in two volumes, one covering general libraries and the library information profession, and the other being concerned with special libraries, materials and processes. All the topics in the previous volume are included, except for the chapter on Buildings and Equipment, the contents of which have been incorporated into other chapters. All the contributors were asked to describe the last five years' major events and publications in their fields, and, generally, to limit their contributions to about 7,500 words, with no restriction on the number of bibliographical references. All authors were requested to tackle their subjects thoroughly while conforming to their own personal and individual styles. No attempt has been made to impose an overall editorial style, or to avoid the duplication which results from writers covering specific, but inevitably overlapping, areas of interest. Cross references have not been inserted in the text from chapter to chapter, where duplication occurs, but a detailed subject index provides for readers wishing to approach the review with an interest in any specific area or topic. A separate list of acronyms and abbreviations appears in each volume, representing all such entries identified in both volumes.

Abstract

Environmental changes are the result of complex interplay among a number of natural and human-related systems. The global ggregate of interactive linkanges among the major systems that affect the environment has become defined as 'global change', The term is intended to encompass the full range of global issues and interactions concerning natural and human-induced changes in the earth's environment. The Global Change Research Act of 1990 defines global change as 'changes in the global environment (including alterations in climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter understanding and predicting the cvauses and impacts of; and potential chnages in, atmospheric ozone and UV radiation; and natural climate fluctuations over seasonal to interannual time periods. Other related global issues include desertification, deforstation, land use management, and preservation of ecosystems". These articles deal with how the federal agencies and other organizations are working together to address the critical issues of our earth's changing environment

Abstract

Updated version of an earlier edition which underlines, on the one hand, the growing importance of grey literature as an information source and the need for guidelines for its further exploitation and, on the other hand the many changes which are taking place, not least with respect to electronic publishing and the rise of the Internet and WWW. Individual chapters deal with specific issues, including: the nature and development of grey literature; grey literatur collections and methods of acquisition; bibliographic control; cataloguing and indexing; specialist means of distribution, microforms and the Internet; theses, translations and meetings papers; aerospace; life sciences; the European Community; education; energy; science and technology; keys to reports series codes; trade literature; and a list of useful addresses of organizations and contacts
