    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
    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

    Abstract
    Abstracts enable users to judge the relevance of articles, provide a summary and may be a substitute for the original document. Defines abstracts and considers who they are written be according to the American National Standards Institute (ANSI) and other sources. Distinguishes between indicative and informative abstracts. Informative abstracts are preferred by ANSI and ERIC. Discusses the content and procedures for abstracting, writing style, tests of quality and readability and informativeness. Presents statistics analyzing abstracts from 3 general interest databases and on abstract length and type

    Abstract
    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
    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
    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
    Purpose - This article aims to focus on usage data in respect to full-text downloads of journal articles, which is considered an important usage (satisfaction) metric by librarians and publishers. The purpose is to evaluate the evidence regarding full-text viewing by pooling together data on the full-text viewing of tens of thousands of users studied as part of a number of investigations of e-journal databases conducted during the Virtual Scholar research programme. Design/methodology/approach - The paper reviews the web logs of a number of electronic journal libraries including OhioLINK and ScienceDirect using Deep Log Analysis, which is a more sophisticated form of transactional log analysis. The frequency, characteristics and diversity of full-text viewing are examined. The article also features an investigation into the time spent online viewing full-text articles in order to get a clearer understanding of the significance of full-text viewing, especially in regard to reading. Findings - The main findings are that there is a great deal of variety amongst scholars in their full-text viewing habits and that a large proportion of views are very cursory in nature, although there is survey evidence to suggest that reading goes on offline. Originality/value - This is the first time that full-text viewing evidence is studied on such a large scale.

    Abstract
    Purpose - This article presents the early findings of an exploratory deep log analysis of journal usage on OhioLINK, conducted as part of the MaxData project funded by the US Institute of Museum and Library Services. OhioLINK, the original "big deal", provides a single digital platform of nearly 6,000 full-text journal for more than 600,000 people in the state of Ohio. The purpose of the paper is not only to present findings from the deep log analysis of journal usage on OhioLINK, but, arguably more importantly, to try test a new method of analysing online information user behaviour - deep log analysis. Design/methodology/approach - The raw server logs were obtained for the period June 2004 to December 2004. For this exploratory study one month (October) of the on-campus usage logs and seven months of the off-campus transaction logs were analysed. Findings - During this period approximately 1,215,000 items were viewed on campus in October 2004 and 1,894,000 items viewed off campus between June and December 2004. The paper presents a number of usage analyses including: number of journals used, titles of journals used, use over time, a returnee analysis and a special analysis of subject, date and method of access. Practical implications - The research findings help libraries evaluate the efficiency of big deal and one-stop shopping for scholarly journals and also investigate their users' information seeking behaviours. Originality/value - The research is a part of efforts to test the applications of a new methodology, deep log analysis, for use and user studies. It also represents the most substantial independent analysis of, possibly, the most important and significant of the journal big deals ever conducted.

    Abstract
    The article presents the early findings of an exploratory deep log analysis of journal usage on OhioLINK, conducted as part of the MaxData project, funded by the U.S. Institute of Museum and Library Services. OhioLINK, the original Big Deal, provides a single digital platform of nearly 6,000 full-text journals for more than 600,000 people; for the purposes of the analysis, the raw logs were obtained from OhioLINK for the period June 2004 to December 2004. During this period approximately 1,215,000 items were viewed on campus in October 2004 and 1,894,000 items viewed off campus between June and December 2004. This article provides an analysis of the age of material that users consulted. From a methodological point of view OhioLINK offered an attractive platform to conduct age of publication usage studies because it is one of the oldest e-journal libraries and thus offered a relatively long archive and stable platform to conduct the studies. The project sought to determine whether the subject, the search approach adopted, and the type of journal item viewed (contents page, abstract, full-text article, etc.) was a factor in regard to the age of articles used.

    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
    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.
