- Abstract
- A national multi-gigabyte-per-second research and education network known as the NREN is to be established by 1996, according to the High Performance Computing Act of 1991 passed in Dec 1991. NREN, referred to as the information highway is expected to provide scientific, educational, and economic benefits for the US, and to serve as the basis for an all-encompassing National Information Infrastructure available to all citizens. An annotated bibliography presenting a representation of the literature that provides a history of the NREN as well as a sense of the evolving concerns and visions of this exciting revolution of the Information Age. Includes items that offer general and specific background information, and visions, viewpoints, and issues related to the NREN

- Abstract
- Reports on a study assessing statewide electronic network initiatives using the Maryland Sailor network as a case study. Aims to develop assessment techniques and indicators for the evaluation of statewide electronic networks. Defines key components of the statewide networked environment. Develops and operationalizes performance measures for networked information technologies and services provided through statewide networks. Explores several methods of evaluating statewide electronic networks. Identifies and discusses key issues and preliminary findings that affect the successful evaluation of statewide networked services

- Abstract
- The proliferation of electronic databases and reduced library collections require researchers to be familiar with an increasing range of bibliographical resources. To assist users in searching multiple databases the PICA network in the Netherlands has developed PiCarta as a single information source. The servie enables users to access bibliographical databases and electronic journals using Boolean logic, fuzzy operators, and subject weighting. The system is, however, dependent upon indexing methods used in original sources

- Abstract
- Considers the possible potential for service development in public libraries offered by the Internet and describes the traditional models of network access and their lack of relevance to public libraries. Describes 2 current research projects currently being undertaken by public libraries to assess the value of the Internet to their services; ITPOINT, a project being conducted at Chelmsley Wood Library, Solihull, UK; and CLIP, the Croydon Libraries Internet peoject. Presents a range of new service paradigms and suggests that public libraries will become even more central to people's lives than they are today

- Abstract
- Library science may well have an essential role to play in efficiently organising the huge amount of Internet information available in the various scientific disciplines. The basic problem is to develop a cataloguing theory sufficiently flexible to cope with the impact of an ever changing store of network data. Such a theory would abondon the utopian idea of a 'catalogue of ctalogues', seeking instead to match each specific user query to the most appropriate catalogue. Examines 2 important USA projects for cataloguing network resources: Digital Libraries Research (funded by the National Science Foundation), which uses a combination of search engines to retrieve net data; and the Internet Public Library. Lists the Management and Library Schools now on the WWW

- Abstract
- In this research, we aim to identify factors that significantly affect the clickthrough of Web searchers. Our underlying goal is determine more efficient methods to optimize the clickthrough rate. We devise a clickthrough metric for measuring customer satisfaction of search engine results using the number of links visited, number of queries a user submits, and rank of clicked links. We use a neural network to detect the significant influence of searching characteristics on future user clickthrough. Our results show that high occurrences of query reformulation, lengthy searching duration, longer query length, and the higher ranking of prior clicked links correlate positively with future clickthrough. We provide recommendations for leveraging these findings for improving the performance of search engine retrieval and result ranking, along with implications for search engine marketing.

- Abstract
- The extant literature demonstrates that the age-related digital divide prevents older adults from enhancing their quality of life. To bridge this gap and promote active aging, this study explores the interplay between social networks and older adults' use of information and communication technology (ICT). Using an action-oriented field research approach, we offered technical help (29 help sessions) to older adult participants recruited from western China. Then, we conducted content analysis to examine the obtained video, audio, and text data. Our results show that, first, different types of social networks significantly influence older adults' ICT use in terms of digital skills, engagement, and attitudes; however, these effects vary from person to person. In particular, our results highlight the crucial role of a stable and long-term supportive social network in learning and mastering ICT for older residents. Second, technical help facilitates the building and reinforcing of such a social network for the participants. Our study has strong implications in that policymakers can foster the digital inclusion of older people through supportive social networks.

- Abstract
- In the light of InfoSeek's extremely lucrative contract with Disney, analyses how it has made such a success of developing an Internet business through advertising revenues, and the imporatnce of powerful search engines. Reports 2 other deals by Internet search companies: NBC's purchase of a minority stake in the portal Snap!, owned by the Computer Network, Inc. and Yahoo's acquisition of Internet Mall and Viaweb which enable it to launch Yahoo Store hosting commerce sites on behalf of other companies allowing them to sell over the Internet. Outlines the possible consequences for users of these developments and of the possibility of Internet startups selling up and quitting the scene

- Abstract
- Online library catalogues and other information resources accessible through network connections offer students and scholars a variety of useful data, but present special problems to remote users. Issues facing the user of Internet-accessible systems include: knowing how to reach a system; finding out what a system contains; mastering commands and menu structures; using appropriate kinds of search terms; and choosing among systems to meet information needs effectively. These issues should be addressed by bibliographic instruction librarians and others who develop instructional units for access to systems on the Internet

- Abstract
- The issue of how teens choose social networks and information communication technologies (ICT's) for personal communication is complex. This study focused on describing how U.S. teens from a highly technological suburban high school select ICT's for personal communication purposes. Two research questions guided the study: (a) What factors influence high school seniors' selection of online social networks and other ICT's for everyday communication? (b) How can social network theory (SNT) help to explain how teens select online social networks and other ICT's for everyday communication purposes? Using focus groups, a purposive sample of 45 teens were asked to discuss (a) their preferred methods for communicating with friends and family and why, (b) the reasons why they chose to engage (or not to engage) in online social networking, (c) how they selected ICT's for social networking and other communication purposes, and (d) how they decided whom to accept as online "friends." Findings indicated that many factors influenced participants' ICT selection practices including six major categories of selection factors: relationship factors, information/communication factors, social factors, systems factors, self-protection factors, and recipient factors. SNT was also helpful in explaining how "friendship" was a major determining factor in their communication media and platform choices.
