    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
    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
    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
    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
    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
    Three questions - what can be studied; how can studies be done; and what can be measured - drive research methods and help to identify information metrics for user studies. User studies can investigate user needs, search strategies, or preferences. Observing and asking, the two main methods for conducting user studies, yield quantitative and qualitative data through studying patterns of behavior and insights into motivation. ciber (Centre for Information Behaviour and the Evaluation of Research, City University, London) is in a good position to continue supporting information user behavior studies that use a variety of methods to gather both qualitative and quantitative data and help establish consistent metrics.

    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
    Database usage data from a random sample of academic and public libraries in the U.S. and Canada reveals patterns of use in selected types of libraries. Library users in both public and academic libraries tend to use commercial online databases most frequently early in the week, mid-day, and at times that correspond to the academic calendar (November in this six-month sample.) The mean number of simultaneous users is correlated with the size of the population served and the number of workstations available, but relatively low numbers of users are simultaneously logged on to research databases at all sizes of libraries. A questionnaire sent to these same libraries identified many other factors that might influence database use, including levels of instruction, availability of remote login, placement of a database on the library's homepage, although none of these factors was found to be statistically significant

    Abstract
    Describes the online end user search service, FirstSearch, provided by OCLC, noting the ways it has developed since its launch in 1991, and the extent of its use in libraries worldwide. Focuses on an important new aspect of the service, the availability of the full text in ASCII format of many of the articles cited in the database, for ordering, viewing and downloading. Also discusses the value of FirstSearch to interloans departments, the costs of the service, enhancements in the searchability of the databases and in the interfaces provided for searching, and the variety of uses to which libraries are putting the service

    Abstract
    Considers some of the human factors in online interaction and Internet use. Discusses the following: users' need for help from libraries and librarians, given the difficulties people continue to have in accessing and using networked information; the challenge of user demands for speedy delivery of information and documents; the trend towards 'humanizing the net' through chat rooms and social agent interfaces (such as Microsoft's Bob); and the problems for libraries of users using the Internet for trivial or pornographic purposes

    Abstract
    Reports on a survey of electronic reference sources and their impact on the work of reference librarians. Reference librarians in university libraries in the Association of Research Libraries (ARL) in the USA were asked to comment on how the library's use of such sources has changed over the past 2 to 3 years and how the work of reference staff has changed. The themes highlighted by the survey include changes in user instructions; the impact of technology; the rising expectations of users; and 'technostress'

    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

    Abstract
    Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

    Abstract
    This article reports the results of a study into the use of discrete journal-article components, particularly tables and figures extracted from published scientific journal articles, and their application to teaching and research. Sixty participants were introduced to and asked to perform searches in a journal-article component prototype that presents individual tables and figures as the items returned in the search results set. Multiple methods, including questionnaires, observations, and structured diaries, were used to collect data. The results are analyzed in the context of previous studies on the use of scientific journal articles and in terms of research on scientists' use of specific journal-article components to find information, assess its relevance, read, interpret, and disaggregate the information found, and reaggregate components into new forms of information. Results indicate that scientists believe searching for journal-article components has value in terms of (a) higher precision result sets, (b) better match between the granularity of the prototype's index and the granularity of the information sought for particular tasks, and (c) fit between journal-article component searching and the established teaching and research practices of scientists.

    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.
