In: Journal of the Association for Information Science and Technology. 67(2016) no.10, S.2344-2361.
Abstract: An international survey of over 3,600 researchers examined how trustworthiness and quality are determined for making decisions on scholarly reading, citing, and publishing and how scholars perceive changes in trust with new forms of scholarly communication. Although differences in determining trustworthiness and authority of scholarly resources exist among age groups and fields of study, traditional methods and criteria remain important across the board. Peer review is considered the most important factor for determining the quality and trustworthiness of research. Researchers continue to read abstracts, check content for sound arguments and credible data, and rely on journal rankings when deciding whether to trust scholarly resources in reading, citing, or publishing. Social media outlets and open access publications are still often not trusted, although many researchers believe that open access has positive implications for research, especially if the open access journals are peer reviewed.

2Nicholas, D. ; Clark, D. ; Rowlands, I. ; Jamali, H.R.: Information on the go : a case study of Europeana mobile users.
In: Journal of the American Society for Information Science and Technology. 64(2013) no.7, S.1311-1322.
Abstract: According to estimates the mobile device will soon be the main platform for searching the web, and yet our knowledge of how mobile consumers use information, and how that differs from desktops/laptops users, is imperfect. The paper sets out to correct this through an analysis of the logs of a major cultural website, Europeana. The behavior of nearly 70,000 mobile users was examined over a period of more than a year and compared with that for PC users of the same site and for the same period. The analyses conducted include: size and growth of use, time patterns of use; geographical location of users, digital collections used; comparative information-seeking behavior using dashboard metrics, clustering of users according to their information seeking, and user satisfaction. The main findings were that mobile users were the fastest-growing group and will rise rapidly to a million by December 2012 and that their visits were very different in the aggregate from those arising from fixed platforms. Mobile visits could be described as being information "lite": typically shorter, less interactive, and less content viewed per visit. Use took a social rather than office pattern, with mobile use peaking at nights and weekends. The variation between different mobile devices was large, with information seeking on the iPad similar to that for PCs and laptops and that for smartphones very different indeed. The research further confirms that information-seeking behavior is platform-specific and the latest platforms are changing it all again. Websites will have to adapt.

3Jamali, H.R. ; Nicholas, D.: Interdisciplinarity and the information-seeking behavior of scientists.
In: Information processing and management. 46(2010) no.2, S.233-243.
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.

4Nicholas, D. ; Huntington, P. ; Jamali, H.R. ; Rowlands, I. ; Fieldhouse, M.: Student digital information-seeking behaviour in context.
In: Journal of documentation. 65(2009) no.1, S.106-132.
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.

In: Aslib proceedings. 60(2008) no.3, S.185-198.
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.

In: Aslib proceedings. 60(2008) no.4, S.290-310.
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.

7Huntington, P. ; Nicholas, D. ; Jamali, H.R.: Website usage metrics : a re-assessment of session data.
In: Information processing and management. 44(2008) no.1, S.358-372.
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.
8Jamali, H.R. ; Nicholas, D.: Information-seeking behaviour of physicists and astronomers.
In: Aslib proceedings. 60(2008) no.5, S.444-462.
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.

9Rowlands, I. ; Nicholas, D. ; Jamali, H.R. ; Huntington, P.: What do faculty and students really think about e-books?.
In: Aslib proceedings. 59(2007) no.6, S.489-511.
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.

10Nicholas, D. ; Huntington, P. ; Jamali, H.R. ; Dobrowolski, T.: Characterising and evaluating information seeking behaviour in a digital environment : Spotlight on the 'bouncer'.
In: Information processing and management. 43(2007) no.4, S.1085-1102.
Abstract: The paper delineates and explains an emerging, but significant, form of digital information seeking behaviour among information consumers, which the authors have called 'bouncing'. The evidence for this behaviour has emerged from five years of deep log analysis studies - an advanced form of transaction log analysis - of a wide range of users of digital information resources. Much of the evidence and discussion provided comes from the scholarly communication field. Two main bouncing metrics were applied in the log studies: site penetration, which is the number of items or pages viewed in a session, and return visits. The evidence shows that (1) a high proportion of people view just a few items or pages during a visit to a site and, (2) a high proportion of visitors either do not come back to the site or they did so infrequently. Typically those who penetrated a site least tended to return the least frequently. These people are termed 'bouncers'. They bounce into the site and then bounce out again, presumably, to another site, as a high proportion of them do not appear to come back again. Possible explanations - negative and positive, for the form of behaviour are discussed.
11Nicholas, D. ; Huntington, P. ; Jamali, H.R. ; Tenopir, C.: What deep log analysis tells us about the impact of big deals : case study OhioLINK.
In: Journal of documentation. 62(2006) no.4, S.482-508.
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.
12Huntington, P. ; Nicholas, D. ; Jamali, H.R. ; Tenopir, C.: Article decay in the digital environment : an analysis of usage of OhioLINK by date of publication, employing deep log methods.
In: Journal of the American Society for Information Science and Technology. 57(2006) no.13, S.1840-1851.
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.
13Nicholas, D. ; Nicholas, P. ; Jamali, H.R. ; Watkinson, A.: ¬The information seeking behaviour of the users of digital scholarly journals.
In: Information processing and management. 42(2006) no.5, S.1345-1365.
Abstract: The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars - academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name 'deep'. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber ("Big Deal", non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session.

14Williams, P. ; Nicholas, D. ; Gunter, B.: E-learning: what the literature tells us about distance education : an overview.
In: Aslib proceedings. 57(2005) no.2, S.109-122.
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.

In: Journal of documentation. 60(2004) no.3, S.245-265.
Abstract: Examines statistically the public's use and attitudes towards interactive and personal health services via an online questionnaire survey and enhances these data with an expert assessment of a number of consumer health sites and their services. Over a period of three weeks more than 1,300 people responded to an online questionnaire produced by The British Life and Internet Project. Of the respondents, 81 per cent were British. The likely potential uptake figure for support group participation among Internet health users is about 20 per cent while around 11 to 13 per cent will go online to describe a medical condition. Those in poor heath were approximately ten to 13 times more likely to have participated in an online support group. Those aged over 65 were four times as likely to e-mail their doctor. More positive health outcomes were associated with those respondents that participated in online support groups and the least number of health outcomes were associated with those people that maintained e-mail contact with a doctor or surgery.

16Nicholas, D. ; Huntington, P. ; Williams, P. ; Dobrowolski, T.: Re-appraising information seeking behaviour in a digital environment : bouncers, checkers, returnees and the like.
In: Journal of documentation. 60(2004) no.1, S.24-43.
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.

17Nicholas, D. ; Huntington, P. ; Williams, P.: ¬The characteristics of users and non-users of a kiosk information system.
In: Aslib proceedings. 56(2004) no.1, S.48-61.
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.

In: Aslib proceedings. 55(2003) nos.5/6, S.261-276.
Abstract: In the UK, both anecdotal and research evidence points to ever greater and more sophisticated use of the Web to provide health information and advice. The study reported here adds to this research with an online survey of Internet users' reported use of the Web to access information about health and their opinions about the advice that can be obtained there. Over a period of three weeks more than 1,300 people responded to an online questionnaire produced by The British Life and Internet Project; 81 per cent or 997 of the respondents were British. The prime purpose of the questionnaire was to obtain information on the characteristics of the users of health information Web sites, to obtain feedback regarding for what they used online health sites and what were the perceived outcomes associated with using online health information.

In: Aslib proceedings. 55(2003) nos.1/2, S.84-109.
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.
