Abstract

The Digital Library Federation is a consortium of research libraries and related organizations in the United States that are pioneering in the use of electronic-information technologies. Each of the DLF's members, mostly research libraries, contributes to a capital fund and an annual budget to support the organization, which is administered by a directorate within the U.S. Council an Library and Information Resources. A Steering Committee, on which each member Institution is represented, guides the work, which has focused an coordinating research, identifying standards and »best practices« for digital library development, and helping to start projects that libraries need but cannot easily develop individually.The DLF convenes task forces, issues publications, sponsors a biannual Digital Library Forum, and maintains a Web site.

Abstract

Constructivism palces emphasis on helping learners create or modify internal models on which to build knowledge and foster experiences which facilitate further knowledge construction. An understanding of models and the use of analogy can be a tool to help facilitate understanding and knowledge construction in new learning environemnts such as the Internet

Abstract

An HTTP based resource discovery system called Discover has been built that provides a single point of access to over 500 WAIS servers. Discover provides 2 key services: query refinement and query routing. Query refinement helps a user improve a query fragment to describe the user's interests more precisely. Once a query has been refined and describes a manageable result set, query routing automatically forewards the query to the WAIS servers that contain relevant documents. Abbreviated descriptions of WAIS sites called content lables are used by the query routing provides an effective way to discover resources in a large universe of documents. Expansion of query fragments is essential in helping one use a large, dynamically changing, heterogenous distributed information system

Abstract

This paper investigates the availability of women's sites on the Internet in the light of the research that has been conducted into women, communications and technology. The paper draws upon a systematic evaluation of ten women's sites, covering a range of sectors including general sites, business, health and technology. The evaluation reveals that such sites offer useful sources of information on a range of subjects of potential interest to women and that they are stable and accessible resources. The sites tend to be freely accessible and apparently reputable, with little evidence of commercialism. However, there are concerns about the lack of security on the sites and a poor provision of the kind of information that is necessary to measure their authority and reliability. While all sites offer some form of interactivity, they tend to offer in each case only a small proportion of the interactive functions that might be enabled and demonstrate little awareness of the significance of these in helping women to network effectively.

Abstract

Purpose - The purpose of this paper is to report an empirical investigation into conceptions of the "invisible web". Design/methodology/approach - This was an exploratory qualitative study based on in-depth semi-structured interviews with 15 members of academic staff from three biology-related departments at the University of Sheffield. Concepts emerged from an inductive analysis of the interview data to form a tentative model. Findings - A distinction is drawn between technical objective conceptions of the "invisible web" that commonly appear in the literature, and a cognitive subjective conception based on searchers' perceptions of search failure, and a tentative model of "cognitive invisibility" is presented. The relationship between objective and subjective conceptions, and implications for training, are discussed. Research limitations/implications - The research was qualitative and exploratory, designed to elicit sensitising concepts and to "map the territory". It thus aims to provide a tentative model that could form the basis for more systematic study. Such research could investigate the validity of the categories in different and/or larger samples, seek further to illuminate, challenge, extend or refute the model, and address issues of generalisability. Practical implications - The paper presents a conceptual model that is intended to be a useful reference point for researchers wishing to investigate user-based aspects of search failure and the invisible web. It may also be useful to trainers and those interested in developing information literacy, in that it differentiates technical objective and cognitive subjective conceptions of "invisibility, and discusses the implications for helping searchers develop more effective searching capabilities. Originality/value - The paper offers an alternative cognitive subjective view of "web invisibility" to that more commonly presented in the literature. It contributes to a still small body of empirical research into user-based aspects of the invisible web.

Abstract

Purpose - This paper reports the findings of a study designed to explore web searchers' perceptions of the causes of their search failure and success. In particular, it seeks to discover the extent to which the constructs locus of control and attribution theory might provide useful frameworks for understanding searchers' perceptions. Design/methodology/approach - A combination of inductive and deductive approaches were employed. Perceptions of failed and successful searches were derived from the inductive analysis of using open-ended qualitative interviews with a sample of 37 biologists at the University of Sheffield. These perceptions were classified into "internal" and "external" attributions, and the relationships between these categories and "successful" and "failed" searches were analysed deductively to test the extent to which they might be explainable using locus of control and attribution theory interpretive frameworks. Findings - All searchers were readily able to recall "successful" and "unsuccessful" searches. In a large majority of cases (82.4 per cent), they clearly attributed each search to either internal (e.g. ability or effort) or external (e.g. luck or information not being available) factors. The pattern of such relationships was analysed, and mapped onto those that would be predicted by locus of control and attribution theory. The authors conclude that the potential of these theoretical frameworks to illuminate one's understanding of web searching, and associated training, merits further systematic study. Research limitations/implications - The findings are based on a relatively small sample of academic and research staff in a particular subject area. Importantly, also, the study can at best provide a prima facie case for further systematic study since, although the patterns of attribution behaviour accord with those predictable by locus of control and attribution theory, data relating to the predictive elements of these theories (e.g. levels of confidence and achievement) were not available. This issue is discussed, and recommendations made for further work. Originality/value - The findings provide some empirical support for the notion that locus of control and attribution theory might - subject to the limitations noted above - be potentially useful theoretical frameworks for helping us better understand web-based information seeking. If so, they could have implications particularly for better understanding of searchers' motivations, and for the design and development of more effective search training programmes.

Abstract

Vernetzung und Netzwerke finden sich allerorten, haben vielerlei Qualität und Materialität, erfüllen diverse Zwecke und Funktionen und konstituieren unterschiedliche Infrastrukturen, nicht nur kommunikativer und sozialer Art. Mit der Entwicklung und Verbreitung der Informationstechnik, der globalen Transport- und Vermittlungssysteme und endlich der anhaltenden Digitalisierung werden der Begriff und die damit bezeichnete Konnektivität omnipräsent und auf digitale Netze fokussiert, die im Internet als dem Netz der Netze seinen wichtigsten und folgenreichsten Prototypen findet. Dessen Entwicklung wird kompakt dargestellt. Die bereits vorhandenen und verfügbaren Anwendungsfelder sowie die künftigen (Industrie 4.0, Internet der Dinge) lassen revolutionäre Umbrüche in allen Segmenten der Gesellschaft erahnen, die von der nationalstaatlichen Gesetzgebung und Politik kaum mehr gesteuert und kontrolliert werden, neben unbestreitbar vielen Vorzügen und Verbesserungen aber auch Risiken und Benachteiligungen zeitigen können.

Abstract

Die Berücksichtigung der Informationsbedarfe und Informationsgewohnheiten ihrer jeweiligen Zielgruppe ist ein wesentliches Charakteristikum desAngebots der Virtuellen Fachbibliotheken Technik und Physik: Von Ingenieuren und Physikern gestellte Anforderungen an ein Informationsangebot werden in den Virtuellen Fachbibliotheken Technik und Physik umgesetzt, um demAnspruch gerecht zu werden, einen integrierten Zugang zu fachrelevanten Informationen und Dienstleistungen zu bieten. Dabei ist nicht nur bei derAuswahl der bereitgestellten Informationsquellen, sondern insbesondere auch bei derAufbereitung (wie z.B. der sachlichen Erschließung) und Präsentation der Inhalte und Angebote der Virtuellen Fachbibliotheken auf fachspezifische Gewohnheiten und Konventionen zu achten. Kooperationen z.B. mit Fachwissenschaftlern und mit Informationslieferanten sind für die Bereitstellung eines umfassenden und qualitativ hochwertigen Angebots wesentlich.
