    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
    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 located in a variety of locations to provide the public with ready access to health information. This paper examines, via a questionnaire, the characteristics of adult users of a surgery-based kiosk. The Esk Medical Centre is in Musselburgh, near Edinburgh. Just under 200 questionnaires were returned and analysed. The research establishes characteristics of users and non-users, how the kiosk fits in with other consumer information sources, what health outcomes result from using the kiosk, and reasons for non-use. The main finding is that the respondents' attitude and previous experience with information technology has an impact on whether the touch-screen kiosk is used.

    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.

    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
    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
    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
    There is very little qualitative data on what impact the Internet is having on information seeking in the workplace. Using open-ended interviews, questionnaires and observation, the impact of the Internet on the British Media was assessed. The focus was largely on newspapers, with The Guardian being covered in some depth. Over 300 journalists and media librarians were surveyed. It was found that amongst traditional journalists use was light. Poor access to the Internet - and good access to other information resources - were largely the reasons for this. Of the journalists it was mainly the older and more senior journalists and the New Media journalists who used the Internet. Librarians were also significant users. Searching the World Wide Web was the principal Internet activity and use was generally conservative in character. Newspapers and official sites were favoured, and searches were mainly of a fact-checking nature. Email was used on a very limited scale and was not regarded as a serious journalistic tool. Non-users were partly put off by the Internet's potential for overloading them with information and its reputation for producing information of suspect quality. Users generally dismissed these concerns, dealing with potential overload and quality problems largely by using authoritative sites and exploiting the lower quality data where it was needed. Where the Internet has been used it has not been at the expense of other information sources or communication channels, but online hosts seem to be at most risk in the future.

    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.
