- Abstract
- Reports a survey of all academic members of the Association of Research Libraries in the 4th quarter of 1997 which examined how academic libraries incorporate electronic information sources into their reference activities and the effects on libraries services. There was a response rate of 68 per cent, Compares results surveys carried out in 1991 and 1994. The survey covered: numbers of computers access options (intermediary, end user online, CD-ROM locally loaded databases or those accessible through the library catalogue and the Internet. There is a trend away from print resources, particularly indexing and abstracting materials, and away from CD-ROM LANs and local loading of databases towards remote online resources

- Abstract
- Describes the variety of search services supporting library reference functions offered by the RLG in the USA. The best known of these is RLIN, the massive bibliographic database and related services originally developed for shared cataloguing. In the last few years RLG has added CitaDel, an online search system that provides access to indexing/abstracting databases; and Zephyr, a Z39.50 server that amkes the RLIN and CitaDel databases searchable through a library's online catalogue. RLG also offers document delivery connections, including Ariel and Internet based document delivery software, for a full complement of online reference support for academic and public libraries

- Reports on a survey of ARL (Ass. of Research Libraries) members in the USA in 1994, which sought to find out the electronic reference services that are offered by these libraries and how the services affect reference staff, the expectations of users, and user instruction. The services covered include CD-ROM, intermediary online searching, end user online (e.g. FirstSearch), tape loaded databases and user access to the Internet, including electronic mail facilities. Highlights the additional workload the provision of these services involves, and the sometimes unrealistic expectations of users especially with regard to Internet resources

- Abstract
- In 1973 F. W. Lancaster published the first textbook about online information retrieval (with E. G. Fayen). That text and his later writings and books on the topics relating to online searching set the precedent for many books to follow. His early work also advocated many changes to the state-of-the-art systems and anticipated many of the characteristics of modern online information retrieval systems. Although the basic underlying structure of modern systems is still similar to what Lancaster wrote about thirty years ago, many of the changes he advocated have occurred. From an era of bibliographic databases on command-driven systems searched by library professionals, online systems have evolved to have friendlier interfaces, include full texts or links to full texts, and are targeted to the end users of the information. The information industry has evolved, as have the online search systems and tools that are so commonplace today.

- Abstract
- This exploratory study examines how design engineers and technical professionals (hereafter referred to as engineers) in innovative high-tech firms in the United States and India use information in their daily work activities including research, development, and management. The researchers used naturalistic observation to conduct a series of daylong workplace observations with 103 engineers engaged in product design and testing in four U.S.- and two India-based firms. A key finding is that engineers spend about one fourth of their day engaged in some type of information event, which was somewhat lower than the percentage identified in previous research. The explanation may be rooted in the significant change in the information environment and corporate expectations in the last 15 years, which is the time of the original study. Searching technology has improved, making searching less time consuming, and engineers are choosing the Internet as a primary source even though information may not be as focused, as timely, or as authoritative. The study extends our understanding of the engineering workplace, and the information environment in the workplace, and provides information useful for improving methods for accessing and using information, which could ultimately lead to better job performance, facilitate innovation, and encourage economic growth.

- Abstract
- Report of a survey 96 (out of 119) US and Canadian member libraries of the Association of Research Libraries (ARL) to determine their use of on-line and CD-ROM data bases, including OPACs. 4 catalogues were identified: on-line mediated searching (97%); CD-ROMs (96%); end-user on-line searching (45%); and locally mounted magnetic tapes (37,5%). The latter option is expected to be the most widely used option in the new future. Although CD-ROM caused some migration from on-line, most migration was from printed sources to CD-ROM. Tables show: on-line hosts most used for intermediary on-line searching; on-line data bases most after searched by intermediaries; end user on-line systems offered by most libraries; the 20 most popular CD-ROM data bases; and the 8 magnetic tape data bases accessible on OPACs

- Abstract
- This article presents part of phase 2 of a research project funded by the NSF-National Science Digital Library Project, which observed how academic users interact with the ScienceDirect information retrieval system for simulated class-related assignments. The ultimate goal of the project is twofold: (1) to find ways to improve science and engineering students' use of science e-journal systems; (2) to develop methods to measure user interaction behaviors. Process-tracing technique recorded participants' processes and interaction behaviors that are measurable; think-aloud protocol captured participants' affective and cognitive verbalizations; pre- and post-search questionnaires solicited demographic information, prior experience with the system, and comments. We explored possible relationships between affective feelings and cognitive behaviors. During search interactions both feelings and thoughts occurred frequently. Positive feelings were more common and were associated more often with thoughts about results. Negative feelings were associated more often with thoughts related to the system, search strategy, and task. Learning styles are also examined as a factor influencing behavior. Engineering graduate students with an assimilating learning style searched longer and paused less than those with a converging learning style. Further exploration of learning styles is suggested.

- Abstract
- Purpose - This article is an edited version of a report commissioned by the British Library and JISC to identify how the specialist researchers of the future (those born after 1993) are likely to access and interact with digital resources in five to ten years' time. The purpose is to investigate the impact of digital transition on the information behaviour of the Google Generation and to guide library and information services to anticipate and react to any new or emerging behaviours in the most effective way. Design/methodology/approach - The study was virtually longitudinal and is based on a number of extensive reviews of related literature, survey data mining and a deep log analysis of a British Library and a JISC web site intended for younger people. Findings - The study shows that much of the impact of ICTs on the young has been overestimated. The study claims that although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than read and do not possess the critical and analytical skills to assess the information that they find on the web. Originality/value - The paper reports on a study that overturns the common assumption that the "Google generation" is the most web-literate.

- Abstract
- Describes the online end user search service, FirstSearch, provided by OCLC, noting the ways it has developed since its launch in 1991, and the extent of its use in libraries worldwide. Focuses on an important new aspect of the service, the availability of the full text in ASCII format of many of the articles cited in the database, for ordering, viewing and downloading. Also discusses the value of FirstSearch to interloans departments, the costs of the service, enhancements in the searchability of the databases and in the interfaces provided for searching, and the variety of uses to which libraries are putting the service

- Abstract
- Looks to the future of traditional online services, in light of the rising use of the WWW, which brings authors or publishers and readers directly together, without the intermediary role played by online vendors. Gives examples of changes in ownership of online services in the last half of 1997, and notes that the changes all suggest that online vendors must nkow their best markets and stick to them. Concludes that many online vendors will survive but in ne configurations and often with new owners

- Abstract
- Reports on a survey of electronic reference sources and their impact on the work of reference librarians. Reference librarians in university libraries in the Association of Research Libraries (ARL) in the USA were asked to comment on how the library's use of such sources has changed over the past 2 to 3 years and how the work of reference staff has changed. The themes highlighted by the survey include changes in user instructions; the impact of technology; the rising expectations of users; and 'technostress'

- Abstract
- Database usage data from a random sample of academic and public libraries in the U.S. and Canada reveals patterns of use in selected types of libraries. Library users in both public and academic libraries tend to use commercial online databases most frequently early in the week, mid-day, and at times that correspond to the academic calendar (November in this six-month sample.) The mean number of simultaneous users is correlated with the size of the population served and the number of workstations available, but relatively low numbers of users are simultaneously logged on to research databases at all sizes of libraries. A questionnaire sent to these same libraries identified many other factors that might influence database use, including levels of instruction, availability of remote login, placement of a database on the library's homepage, although none of these factors was found to be statistically significant

- Abstract
- Discusses the familiar problem of users are now confronted with the needs to impose order on myriad sources of information and to present them in an integrated way to users. Describes an attempt to provide such integration in the engineering field, Engineering Information Village, or Ei Village, produced by Engineering Information Inc. It resembles a WWW site, and integrates a traditional online abstracting and indexing service with access to WWW sites in the engineering field, contacts to engineering consultants, and access to other sources of interest to engineers. Explains how the metaphor of the village is carried though in the service and stresses the vetting process which seeks to guarantee that sources provided are authoritative. Also details the pricing of the service

- Abstract
- Discusses the rapid increase in the availability of the full text of journals, newspapers, documents and books, online and in CD-ROM, in the recent past, noting that full text now makes up 49% of word oriented databases. Explains the differences between image files, ASCII fullt text which is searchable, and ASCII full text which is displayable and downloadable but not searchable, and gives examples of these. Highlights the full text databases which are being introduced by the H.W. Wilson Company
