    Abstract
    BLAISE-LINE provides online access to all of the British Library's major catalogues as well as to other major bibliographies. With its MARC records, Dewey numbers and Library of Congress headings (LCSH), BLAISE-LINE remains a tradtional library oriented online service. Presents the results of a survey of 37 libraries using BLAISE-LINE to find out what users thought of it and how it compared to the more modern systems of enduser, fulltext, CD-ROM and the Internet. The principal uses to which respondents put BLAISE-LINE were bibliographical checking, answering subject enquiries, and obtaining interlibrary loans. The survey also covered frequency of use, ease of use, problems in using the system, cost issues, and training and support. Findings show that professional librarians value the efficiency of BLAISE-LINE above the user friedliness of other systems

    Abstract
    Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often 'sessionization') is fraught with difficulty in that there is no way of determining from a transactional log file that a user has ended their session. No one logs out. Instead a session delimiter has to be applied and this is typically done on the basis of a standard period of inactivity. To date researchers have discussed the issue of a time out delimiter in terms of a single value and if a page view time exceeds the cut-off value the session is deemed to have ended. This approach assumes that page view time is a single distribution and that the cut-off value is one point on that distribution. The authors however argue that page time distribution is composed of a number of quite separate view time distributions because of the marked differences in view times between pages (abstract, contents page, full text). This implies that a number of timeout delimiters should be applied. Employing data from a study of the OhioLINK digital journal library, the authors demonstrate how the setting of a time out delimiter impacts on the estimate of page view time and the number of estimated session. Furthermore, they also show how a number of timeout delimiters might apply and they argue that this gives a better and more robust estimate of the number of sessions, session time and page view time compared to an application of a single timeout delimiter.

    Abstract
    Nowadays, end-users have quick and direct access to massive amount of information available on the Net. However, this information is unorganized expecting users to be able to identify and evaluate it in accordance with their information needs. Subject based information Gateways SBIG, organized collections of networked information, provide users with a catalogue of authoritative Internet resources, which can be searched and/ or browsed. This paper provides an evaluation of one such gateway - the Art, Design, Architecture & Media Gateway ADAM. It provides information on who these users are, how often they use the service, what their reasons for use are, which search methods and services they prefer and what are the advantages and disadvantages of an online information service.

    Abstract
    This work tackles one of the fundamental problems of information management - how to get the right information to the right person at the right time. It provides a practical framework to enable information services to gather information from users in order to aid information system design, and to monitor the effectiveness of an information service. This new edition has been fully revised and now has increased coverage of the Internet. The Web raises many problems when it comes to meeting information needs - authority and overload, for example - and these problems make an effective information needs analysis even more crucial. There is a new methodology section on Web log analysis and focus group interviews. Practical advice is given concerning interview technique and an interview schedule is included.

    Abstract
    Purpose - This study provides evidence on the actual information-seeking behaviour of students in a digital scholarly environment, not what they thought they did. It also compares student information-seeking behaviour with that of other academic communities, and, in some cases, for practitioners. Design/methodology/approach - Data were gathered as part of CIBER's ongoing Virtual Scholar programme. In particular log data from two digital journals libraries, Blackwell Synergy and OhioLINK, and one e-book collection (Oxford Scholarship Online) are utilized. Findings - The study showed a distinctive form of information-seeking behaviour associated with students and differences between them and other members of the academic community. For example, students constituted the biggest users in terms of sessions and pages viewed, and they were more likely to undertake longer online sessions. Undergraduates and postgraduates were the most likely users of library links to access scholarly databases, suggesting an important "hot link" role for libraries. Originality/value - Few studies have focused on the actual (rather than perceived) information-seeking behaviour of students. The study fills that gap.

    Abstract
    Purpose - The purpose of this article is to report on a large-scale survey that was carried out to assess academic users' awareness, perceptions and existing levels of use of e-books. The survey also seeks to find out about the purposes to which electronic books were put, and to obtain an understanding of the most effective library marketing and communication channels. Design/methodology/approach - An e-mail invitation to participate in the survey was distributed to all UCL staff and students (approximately 27,000) in November 2006, and 1,818 completions were received, an effective response rate of at least 6.7 per cent. Statistical analyses were carried out on the data using Software Package for Social Sciences (SPSS). Findings - The survey findings point to various ways in which user uptake and acceptance of e-books may be encouraged. Book discovery behaviour, a key issue for publishers and librarians in both print and electronic environments, emerges as a critical focus for service delivery and enhancement. Originality/value - The survey is part of an action research project, CIBER's SuperBook, that will further investigate the issues raised in this initial benchmarking survey using deep log analysis and qualitative methods. The paper partly fills the gap in the literature on e-books which has mainly focused on usage and not the users.

    Abstract
    Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

    Abstract
    Purpose - The CIBER group at University College London are currently evaluating a distance education initiative funded by the Department of Health, providing in-service training to NHS staff via DiTV and satellite to PC systems. This paper aims to provide the context for the project by outlining a short history of distance education, describing the media used in providing remote education, and to review research literature on achievement, attitude, barriers to learning and learner characteristics. Design/methodology/approach - Literature review, with particular, although not exclusive, emphasis on health. Findings - The literature shows little difference in achievement between distance and traditional learners, although using a variety of media, both to deliver pedagogic material and to facilitate communication, does seem to enhance learning. Similarly, attitudinal studies appear to show that the greater number of channels offered, the more positive students are about their experiences. With regard to barriers to completing courses, the main problems appear to be family or work obligations. Research limitations/implications - The research work this review seeks to consider is examining "on-demand" showing of filmed lectures via a DiTV system. The literature on DiTV applications research, however, is dominated by studies of simultaneous viewing by on-site and remote students, rather than "on-demand". Practical implications - Current research being carried out by the authors should enhance the findings accrued by the literature, by exploring the impact of "on-demand" video material, delivered by DiTV - something no previous research appears to have examined. Originality/value - Discusses different electronic systems and their exploitation for distance education, and cross-references these with several aspects evaluated in the literature: achievement, attitude, barriers to take-up or success, to provide a holistic picture hitherto missing from the literature.

    Abstract
    Purpose - The study aims to examines two aspects of information seeking behaviour of physicists and astronomers including methods applied for keeping up-to-date and methods used for finding articles. The relationship between academic status and research field of users with their information seeking behaviour was investigated. Design/methodology/approach - Data were gathered using a questionnaire survey of PhD students and staff of the Department of Physics and Astronomy at University College London; 114 people (47.1 per cent response rate) participated in the survey. Findings - The study reveals differences among subfields of physics and astronomy in terms of information-seeking behaviour, highlights the need for and the value of looking at narrower subject communities within disciplines for a deeper understanding of the information behaviour of scientists. Originality/value - The study is the first to deeply investigate intradisciplinary dissimilarities of information-seeking behaviour of scientists in a discipline. It is also an up-to-date account of information seeking behaviour of physicists and astronomers.

    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
    Adopting an intradisciplinary perspective, this article evaluates the information-seeking behavior of academics from different subfields of physics and astronomy. It investigates the effect of interdisciplinarity (reliance on the literature of other subjects) and the scatter of literature on two aspects of the information-seeking behavior: methods used for keeping up-to-date and for identifying articles. To this end a survey of 114 PhD students and staff at the Department of Physics and Astronomy at the University College London was carried out. The findings showed that the subfields that are more interdisciplinary or have a more scattered literature are more likely to use general search facilities for finding information. The study also showed that cross-disciplinary use of the literature is not necessarily an indicator of scattered literature. The study reveals intradisciplinary differences among physicists and astronomers in terms of their information-seeking behavior and highlights the risk of overlooking the characteristics of information-seeking behavior of specialized subject communities by focusing on very broad subject categories.

    Abstract
    Outlines a structure for analysing information needs. The purpose of the structure is to enable data on users to be collected in a systematic and routine manner. The form of analysis is demonstrated through a consideration of the information needs of newspaper journalists. Aspects of information need considered are: subject, nature, function, viewpoint, authority, quantity, quality, place of origin, speed of delivery, and processing/packaging. Considers the barriers to meeting information needs and training, time, resources, access and information overload. Also assesses the library's role in meeting information needs

    Abstract
    Touch-screen kiosks are situated in a variety of locations to provide the public with ready access to health information. This paper examines their use, via the transactional logs, and makes comparisons between the types of organisation in which the kiosks are housed. Twenty-one kiosks were selected and categorised into four groups - pharmacy, hospital, information centre and surgery. A small case study features a supermarket kiosk. Details of nearly 90,000 user sessions and 750,000 page views were used for the comparison. Comparisons between sites were made in terms of number of users, their age and gender, trends over time, the number of sessions conducted, page view time, session duration, pages viewed, site penetration, number of pages printed and health topics viewed. There were considerable differences between the kiosk locations. This early research provides the quantitative foundation for a fuller study of kiosk location and the differences in perceptions of the quality/authority of kiosk data.

    The digital revolution represents an historic challenge to all information handlers who are likely to experience the rearrangement and redefintion of their roles and relationships. Discusses the threats, changes and challenges of the Internet to journalistic professionals, especially print journalists. These include: loss of monopoly in news production; loss of the exclusivity of news; loss of the need for news arbitrators, authorities and guardians; and the possibility that journalists may be peddling an obsolete product given that the younger generation do not regard newspapers as especially appealing. Discusses the implications of these facts for the information profession

    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
    Collating data from a number of log and questionnaire studies conducted largely into the use of a range of consumer health digital information platforms, Centre for Information Behaviour and the Evaluation of Research (Ciber) researchers describe some new thoughts on characterising (and naming) information seeking behaviour in the digital environment, and in so doing, suggest a new typology of digital users. The characteristic behaviour found is one of bouncing in which users seldom penetrate a site to any depth, tend to visit a number of sites for any given information need and seldom return to sites they once visited. They tend to "feed" for information horizontally, and whether they search a site of not depends heavily on "digital visibility", which in turn creates all the conditions for "bouncing". The question whether this type of information seeking represents a form of "dumbing down or up", and what it all means for publishers, librarians and information providers, who might be working on other, possible outdated usage paradigms, is discussed.

    Abstract
    Evaluates, through deep log analysis, the impact of "Big Deal" agreements on the online searching behaviour of users of the Emerald digital library Web site, which provides access to more than 150 journals in the fields of business and information science. The purpose of the evaluation was to map the online information seeking behaviour of the digital library user and to see whether those signed-up to a Big Deal arrangement behaved any differently from the others. In general they did. The real surprise proved to be the strong consumer traits of the library's users. Research reported here refers to the first stage of a three-stage research project.

    Abstract
    Presents the results of a survey of 36 banking and finance institutions in the UK on their information professionals' use of the Internet as a source of business information. The survey revealed that less than a third are currently using the Internet. Discusses the disadvantages and advantages of the Internet both as an information source and in terms of management. At the moment the Internet is a complementary information source although in the future it may become an entry-point to other information sources

    Abstract
    Virtually all UK and US newspapers and the vast majority of regional and even local titles are now represented on the web. Indeed, the Yahoo news and media directory lists no less than 114 UK newspapers online (as of November 1998). Broadcasters from the BBC and Sky downwards, and all the famous news agencies (Press Association, Reuters etc.) also boast comprehensive Internet services. With such an array of sources available, the future of mass access to the Internet, possibly via TV terminals, suggests that more and more people may soon opt for this medium to receive the bulk of their news information. This paper gives an overview of the characteristics of the medium illustrated with examples of how these are being used to both facilitate and enhance the content and dissemination of the news product. These characteristics include hyperlinking to external information sources, providing archive access to past reports, reader interactivity and other features not possible to incorporate into more passive media such as the hardcopy newspaper. From a survey of UK and US news providers it is clear that American newspapers are exploiting the advantages of web information dissemination to a far greater extent than their British counterparts, with the notable exception of The Electronic Telegraph. UK broadcasters, however, generally appear to have adapted better to the new medium, with the BBC rivaling CNN in its depth and extent of news coverage, use of links and other elements.
