- 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
- The only monitoring of educators is performed by their internal sense of right and wrong. Following the aggred terms of system contracts, selecting the most appropriate systems for students, keeping up to date with system features, and instilling ethical behaviour in students are at the core of ethics for online educators

- 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
- 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

- 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

- Novice end users were given 2 hours of training in searching a full-text magazine database (Magazine ASAP(TM)) on DIALOG. Subjects searched during 3 to 4 sessions in the presence of a trained monitor who prompted them to think aloud throughout the sessions. qualitative analysis of the transcripts and transaction logs yielded empirical information on user variables (purpose, motivation, satisfaction), uses of the database, move types, and every question users asked during the searches. The spontaneous, naturalistic questions were categorized according to affective, cognitive, and sensorimotor speech acts. Results show that most of the searches were performed for the self and were work related. The most common use of the database was to retrieve full-text articles online and to download and print them out rather than read them on screen. The majority of searches were judged satisfactory. Innovative uses included browsing for background information and obtaining contextualized sentences for language teaching. Searchers made twice as many moves to limit sets as moves to expand sets. Affective questions outnumbered cognitive and sensorimotor questions by two to one. This preponderance of affective micro-information needs during searching might be addressed by new system functions

- 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
- Surveys of the members of the American Astronomical Society identify how astronomers use journals and what features and formats they prefer. While every work field is distinct, the patterns of use by astronomers may provide a glimpse of what to expect of journal patterns and use by other scientists. Astronomers, like other scientists, continue to invest a large amount of their time in reading articles and place a high level of importance an journal articles. They use a wide variety of formats and means to get access to materials that are essential to their work in teaching, service, and research. They select access means that are convenient-whether those means be print, electronic, or both. The availability of a mature electronic journals system from their primary professional society has surely influenced their early adoption of e-journals.

- 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
- Academic and special research libraries in the US and Canada access on average 7,4 online systems. This probably doubles or triples when including CD-ROMs and locally loaded databases. Examines the many ways in which online versions of databases can vary on different systems. Discusses the differences of updating, dates covered, price, subfile structure, field subdivisions, content or inclusion, support features and system search features. Provides statistics on these differences
