This article discusses the approach of two national governments to the use of the World Wide Web (WWW) as a means for providing information and other resources to the public. Each country has a view of information management and information delivery through the WWW. The United States links the actions of agencies to a strategic planning process involving the use of performance indicators, whereas New Zealand has a lesser commitment to information dissemination. Performance indicators reflecting a customer's perspective could apply to U.S. government WWW sites, thereby improving the public's right-to-know, open government, and public access. The article identifies future directions for research and evaluation, and illustrates that government information for both countries need not appear in textual form. 相似文献

Abstract Access to biological information on the World Wide Web continues to grow at a rapid pace. Many resources that previously required a trip to the library are now accessible from the desktop PC. Three major categories of biology Web sites are explored: those with citation information, those functioning as clearinghouses or directories to other Web sites, and those that present biological information in innovative ways. The suggested Web sites are some of the best and may serve as models for future Web development. Many useful citation Web sites are fee-based and are likely to continue as such for the near future; MEDLINE and AGRICOLA are important exceptions. Many significant clearinghouse and information Web sites are not fee-based and allow innovative ways of finding and sharing information. The state of research information on the WWW is not developed enough for the researcher to forego using paper sources. 相似文献

This study reports the results of a survey conducted at Aligarh Muslim University (AMU) to determine the extent to which Internet users are aware and make use of the Internet resources and services. The study examines the information searching behavior of Internet users. A questionnaire and follow-up interviews with the postgraduate students, research scholars and academic staff were conducted to collect data. A total of 489 questionnaires were distributed to the selected sample of eight faculties; 405 valid samples were collected. The data were analyzed according to the background of Internet users, Internet information searching behavior, use of Internet resources and services, quality of Internet information, problems of the Internet access and need for Internet literacy. The study found that the majority of respondents had a 5 year history of Internet access. The academic staff spent more time on the Internet than the students and research scholars. Although Internet search engines were the preferred information searching tool, other methods such as databases, gateways and World Wide Web (WWW) were also used. Online journals and databases were the preferred information sources among the Internet users. Respondents chose e-mail, WWW and search engines as important Internet services. About 60% of respondents believed that the good quality of information on the Internet made it a useful tool for education and research. Slow speed, lack of training and information overload were indicated as some of the factors affecting Internet usage. Further, recommendations are made to improve the use of Internet, including a well-planned Internet literacy program and preparation of subject gateways. 相似文献

A survey to determine attitudes toward end-user searching was made at Loyola University's Medical Center Library using MEDIS, an online full-text and bibliographic medical retrieval system. One hundred forty-one completed questionnaires were analyzed for this report. Information was collected on user familiarity with computers, end-user training, system use, mechanics of searching, and attitudes toward future use. Computer familiarity was highest among the faculty users. Ninety percent of the respondents saw librarians as a crucial agent in training and in providing end-user assistance. Respondents identified five major reasons for using the system: helpfulness, convenience, time savings, rapid feedback, and presentation of needed information. Searching the MEDLINE database rather than the full-text database was the search method of choice. Continued use of both mediated and end-user searching was intended by most of the respondents. Survey results support a perceived need for end-user searching and confirmed recommendations of the Association of American Medical Colleges on medical information science skills. 相似文献

Government publications have long been considered authoritative sources of information regardless of the format [electronic via the World Wide Web (WWW) or paper] they are published in and with little consideration as to how they are researched, written, and published. Given the greater accessibility that the WWW provides the public to this very important source of information on a wide variety of subjects, assessing authoritativeness becomes a bigger and more difficult issue. This preliminary study applies informetric methods, specifically citation analysis, to assess whether the blind trust afforded government publications is appropriate in an important area of public policy that, particularly in Canada, is seen almost as a natural right of citizenship, public health care. The results of this study show that this trust is not misplaced as these publications are well researched and, with or without references, are used without discrimination. 相似文献

As end-user demand for easy access to electronic full text continues to climb, an increasing number of information providers are combining that access with their other products and services, making navigating their Web sites by librarians seeking information on a given product or service more daunting than ever. One such provider of a complex array of products and services is Thomson Scientific. This paper looks at some of the many products and tools available from two of Thomson Scientific's businesses, Thomson ISI and Thomson ResearchSoft. Among the items of most interest to health sciences and veterinary librarians and their users are the variety of databases available via the ISI Web of Knowledge platform and the information management products available from ResearchSoft. 相似文献

Information communication technology (ICT) in government agencies as well as educational and research institutions facilitates an efficient, speedy and transparent dissemination of information to the public and other agencies for performance of government administration activities. The importance of ICT in governance has been recognized the world over. E-governance highlights several elements of good governance such as transparency, accountability, participation, social integration, public financial management reform and development. This study is based on research and personal interviews of selected representatives of the Government of National Capital Territory of Delhi. The findings of this study highlight the role of Internet, particularly the World Wide Web (WWW), which has made it easier for citizens to locate and download official information and to conduct transactions. Information management agencies such as libraries and knowledge centres play a vital role in supporting transparent and accountable governance in this digital era. E-government needs to be integrated into the broader public management framework so as to make a substantial change in the government to citizen (G2C) relationship. 相似文献
