    Abstract
    Librarians at the University of the Pacific, California (UOP) designed a replication of an earlier transaction log study carried out at Adelphi University, New York (LRTS 38(1994) no.3, S.293-305). It was hypothesized that library staff would use a feature that allows the searcher to limit a search by location or material type more often than users. It was also hypothesized that library staff and reference librarians would have a higher success rate than public users. The third hypothesis was that UOP users would perform keyword searches more often than library staff. Studies were conducted in 1995 in 1996 to test these hypotheses to provide comparative data on the search styles of users and staff. Searches of the INNOPAC database, using transaction logs, were performed by 4 terminal groups: public users, technical services staff, public services staff, and reference librarians. It was discovered that replicating a study is not nearly as straightforward as was initially thought. It was also found to be surprisingly difficult to compare year to year data at the same institution; primarily due to a continually changing technological environment

    Abstract
    In information needs, seeking and use (INSU) research, individuals have most commonly been perceived as users (e.g., Kuhlthau, 1991; Dervin & Nilan, 1986; Dervin, 1989; Belkin, 1980). The concept user originates from the user of libraries and other information services and information systems. Over the years the scope of the concept has become wider and it is nowadays often understood in the sense of seekers of information (e.g., Wilson, 1981; Marchionini, 1995) and users of information (e.g., Streatfield, 1983). Nevertheless, the concept has remained ambiguous by being on the one hand universal and on the other hand extremely specific. The purpose of this paper is to map and evaluate views on people whose information behaviour has been in one way or another the core of our research area. The goal is to shed some light on various relationships between the different aspects of doers in INSU studies. The paper is inspired by Dervin's (1997) analysis of context where she identified among other themes the nature of subject by contrasting a `transcendental individual' with a `decentered subject', and Talja's (1997) presentation about constituting `information' and `user' from the discourse analytic viewpoint as opposed to the cognitive viewpoint. Instead of the metatheoretical approach applied by Dervin and Talja, a more concrete approach is valid in the present analysis where no direct arguments for or against the underlying metatheories are itemised. The focus is on doers in INSU studies leaving other, even closely-related concepts (i.e., information, information seeking, knowledge etc.), outside the scope of the paper.

    Abstract
    Reviews work of the Getty Art History Information Program (AHIP), recently renamed the Getty Information Institute, where humanities scholars were trained in DIALOG online searching and then allowed 24 hour unlimited access to DIALOG searching and DIALOG databases and where complete transaction logs were taken to yield the data upon which the Getty Online Searching Project was based. Summarizes results of the study of this subsidized access which was reported in a series of papers by M.J. Bates, who found that searching patterns of humanities researchers differed substantially from previous studies in the sciences and social sciences disciplines. Presents a model of the relative merits and opportunities associated with the various contractual arrangements and incentive strategies employed by AHIP with vendors such as DIALOG, consortia such as the Research Libraries Group, and a CD-ROM publication programme, compared to print publications and the experimental offer of access to some of the AHIP databases over the WWW. The arguments are illustrated by means of 2 case studies, involving: changes in pricing of the Avery Index to Architectural Periodicals; and the Getty Online Searching Project

    Abstract
    Discusses the importance of catalogue use studies, particularly in the context of database development for networking. A literature review reveals that most of the studies are conducted in western countries which may be grouped in 3 categories: user studies; studies relating to search failures; and experiments with methodology. Stresses the need for more such studies in the context of libraries in India, particularly in the view of library network development in the country

    Abstract
    Reviews a series of studies conducted by C.C, Kuhlthau who investigated users' information seeking behaviour in libraries over a 10 year period. In her study she constructed and Information Search Process (ISP) Model which represents aspects of user activities as a whole including feelings, thoughts and actions or behaviour. Argues that, while the ISP model sheds new light on user studies, it has problems in the following areas: problem solving processes; the understanding of 'feelings'; and the method of investigating users' information seeking behaviour. Recommends that the ISP model be reconstructed from different perspectives and verified in areas other than libraries. This may lead to the development of a new model of information seeking

    Abstract
    This paper highlights some of the significant findings from author's PhD: "Factors affecting the end-use of electronic databases in public libraries." Public libraries have a wide range of different types of users who, unlike academic or special library users, are not necessarily information-trained (see Coles, 1998). Whereas the academic, special library user may have specific information needs that can be met by electronic sources, public library users do not necessarily have such specific information needs that can easily be identified and met. Most user surveys have tended to concentrate on the searching and retrieval aspect of information seeking behaviour, whereas this study's user survey focused more on how people perceived and related to Information and Communication Technologies (ICTs). It was not how people searched a particular electronic source, in this case CD-ROM, that was of prime interest but rather whether or not people actually used them at all and the reasons why people did or did not use electronic media. There were several reasons the study looked at CD-ROM specifically. Firstly, CD-ROM is a well established technology, most people should be familiar with CD-ROM/multimedia. Secondly, CD-ROM was, at the start of the study, the only open access electronic media widely available in public libraries. As well as examining why public library users chose to use electronic sources, the paper looks at the types of CD-ROM databases used both in the library and in general Also examined are what sort of searches users carried out. Where appropriate some of the problems inherent in studying end-users in public libraries and the difficulty in getting reliable data, are discussed. Several methods were used to collect the data. I wished to avoid limiting research to a small sample of library sites, the aim was to be as broad in scope as possible. There were two main groups of people 1 wished to look at: non-users as well as CD-ROM users

    Abstract
    Reviews studies of users of OPACs focusing on the research methodology of librarians. Surveys and questionnaires, interviews, observation, controlled experiment and transaction log analysis were used with varying degrees of expertise and success in academic public libraries with a variety of user populations. Poor methodology due to lack of training and funding sharply limit their usefulness in most cases

    Abstract
    Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

    Abstract
    The project explored the ways in which the online catalogue contributes, or does not contribute to the success of library users. Key issues examined included: whether students are really getting appropriate assistance when using the online catalogue; the most common searching successes and failures observed for people using the online catalogue without staff assistance; and the effectiveness of online catalogue use by librarians providing reference assistance compared to other sources (reference books, electronic and printed indexes). Reviews relevant studies of online catalogues and reference success and describes the methodology and results of 3 different online catalogue studies: the Reference Assessment Survey; the online catalogue study of unassisted users; and the document availability study; all conducted at San José State University Library; California, using the Reference Transaction Assessment Instrument. Considers the implications of the results for reference practice and study methodology

    Abstract
    The focus of this study is the search behavior of remote users of the University of California MELVYL Library System, an OPAC. Transaction logs from randomly selected remote user search sessions are analyzed. Descriptive data on the number and type of searches, choice of search mode and database, number of retrievals, number and type of errors, and use of system HELP facilities are presented. The search data have been cross-tabulated with demographic data on the same group of remote users, collected through an online survey conducted by the authors. Effectiveness of system usage is discussed. A case mode is made for the desirability of additional heuristics in the catalog portion of the system

    Abstract
    Presents a pilot study for an Internordic project to monitor the use of online catalogues in the Nordic technological university libraries. Focuses on the use of classification in subject searching, how the UDC is used and the extent of its use. Studies user interaction with the OPACs and improvements to information retrieval in the catalogues using the transaction log method to gather data. The pilot study examnines the TENTTU Books database which is the online union catalogue of the Helsinki Univ. of Technology Library, a multilingual database with true information retrieval. The Internordic study itself will make comparisons between the TENTTU system and the new Virginia Tech Library System. Discusses the users monitored, method of analysis, subject searching in the database, results and how the UDC codes were used. Compares this to other studies conducted in Finland and evaluates the project

    Abstract
    Data from Westminster Libraries on membership, borrowing frequency and stock use is compared with significant studies of public library use from the last 50 years. The article examines the extent of public library use, and the social and demographic factors influencing use. Analysis of book and audio-visual stock use indicates the concentration of demand on a few titles and subjects, and the relationship to what is in demand commercially. Aspects of public library use have remained constant over at least the last 50 years, and across geographical boundaries. Public libraries are used principally for leisure, for borrowing recent fiction, for useful non fiction related to immediate life interests, and for pop music. Quantitative data from library systems provides a different, probably more accurate, picture of the nature and extent of public library use.

    Abstract
    The study of subject access to UK academic library catalogues was based on a questionnaires end out during Summer 1991. 86 out of a possible 110 questionnaires were returned. All universities and polytechniques now have OPACs which are progressing well towards comprehensive bibliographical coverage of their libraries' stocks. The MARC format is now widely used. Subject access strategies are usually based on either Library of Congress Subject Headings or inhouse indexing systems but almost half the OPACs studies have no separate subject searching option based on subject indexing is expensive and future subject indexing strategies are best based on pre-existing controlled vocabularies. Strategies authority control is essential. A limited range of software strategies is recommended including the need to limit search results

    Abstract
    Recently, the importance of application of multiple, qualitative methods has been emphasised in the field of information seeking and retrieval research. (See Fidel 1993; Vakkari 1997). One of the earliest and most ambitious attempts to apply multiple methods was the research project on information needs and information services in local authority social services departments. (Wilson & Streatfield 1977; Wilson, et al., 1979; Wilson 1981). In studies on information needs and seeking qualitative methods have gained a leading position in the 1990's (Vakkari 1997: 451). Indisputably, this is the case when looking at recent information needs, seeking and use research carried out by Algon (1997), Ellen (1998), Barry (1995), Byström (1997), Iivonen (1996), Kirk (1997), Kuhlthau (1993), Solomon (1997) and Sonnenwald and Lievrouw (1996). Furthermore, though the approach of the study is qualitative the application of quantitative techniques is not necessarily excluded. In methodological literature attention is paid to integrating qualitative and quantitative techniques. These methods are not opposite but they complement to each other. In a qualitative study various methods can be combined. Triangulation can be seen in two ways: firstly, to ascertain the validity of research; secondly, to employ the methods that are appropriate to the subject investigated. Application of triangulation in the former way aims at the full, 'objective' picture of the subject studied, while the picture obtained in the latter way is like a kaleidoscope. Thus the ultimate reason for triangulating is to gain deeper understanding of the phenomenon studied.

    Abstract
    Reports results of the Information Access Project, funded by King's College London and the British Library, Research and Development Department, set up to examine the effects of information technology, the electronic library and the Internet on the information seeking behaviour and research behaviour of academics in higher education. The project studied a team of theoretical physicists over 2 years using a qualitative, context situation, user centred methodology. Electronic resources, primarily electronic bulletin boards and electronic mail, were used to access information in 80% of the 48 research projects, ususally in conjunction with traditional methods. Discusses the changes in information activity, changed boundaries and speeding up of the work of the research community; increased visibility for researchers; formalization of the preprint process; replacement of formal with informal peer review; improved access to more current information; and the demise in the use of libraries. Drawbacks reported include: limitations of electronic mail communication; information overload; limitations of reliance on single information sources in terms of their focus; and the reduction in creative active information seeking. The main electronic information source for the high energy physicists, used in the study, was the High Energy Physics Theory (HEPTH) pre-print bulletin board: a service designed to provide rapid access to written research information available before it is published in periodical form
