    Abstract
    Reports results of a study to investigate judgements made by searchers of online catalogues by using transaction log analysis to associate online catalogue searchmethods with decisions so as to retrieve location information. The study used the Mainframe Interface to Libraries Online (MILO), an interface to the Illinois Library Computer Systems Office (ILCSO) online union catalogue for the 45 academic libraries belonging to ILCSO. MILO provides access to a bibliographic database and directly links to another database with circulation and location records. As the latter database only provides location and circulation status, searchers' decisions to make links to such data are seen as an indication that the records being linked represent potentially useful material. Via a transaction log analysis, the linked location records were associated wiht the access points used to retrieve them in order to analyze the value and problems of searchers' uses of specific access points. Transaction logs were analyzed for a 38-day sample of the 1994 logs. Counting of records retrieved through the use of multiple access points (making the total greater than 100%), subject fields were used to access over 30%, author fields to access over 19%, and title fields to access over 51% of all records linked to location information. Other fields were used to retrieve very small percentages of linked records

    Abstract
    The aim of this study is to compare (1) the semantic structures in lay persons' questions addressed to ask-an-expert service in the fields of health, nutrition and social services, and (2) to which extent lay persons' vocabularies are covered by a general thesaurus and a specific thesaurus in each of these fields. As representation of information needs 50 questions were selected concerning both health and nutrition, and 163 concerning social services. The concepts and their expressions in the questions were identified, and their semantic relations were observed and classified into equivalence, hierarchical and associative relations. The semantic structure of questions varied somewhat between the fields observed. Lay persons' expressions were covered most extensively in health, and least extensively in social services. Specific thesaurus covered more extensively expressions in health (65%) than general thesaurus (42%), whereas in nutrition there was no difference (33% vs. 32%), and in social services general thesaurus (21%) covered expressions somewhat better compared to specific thesaurus (15%). In terms of matching both specific and general thesaurus would provide searchers with reasonable support in term selection for query construction in health, but with limited assistance in nutrition and social services.

    Abstract
    Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

    Abstract
    Reports an examination of the results of 114 sessions on the online catalogue, at the Ellis Library, Missouri University at Columbia, to determine what types of searches were conducted and what search modes and fields (title, author) were used. Examination of tranaction logs revealed that title and author searches predominated and that the opportunity to construct Boolean searches was rarely taken advantage of. The searchers themselves reported that they were, on the whole, experienced at using the system; most searched the catalogue at least once a week. This is reflected in the relatively low instance of error and in the fact that most searches produced at least some hits. The majority of errors that were made in the process of searching were typographical

    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.

    Abstract
    The Getty art history information program carried out a two-year project to study how humanities scholars operate as end users of online databases. Visiting scholars at the Getty Center for the History of Art and the Humanities in Santa Monica, California, were offered the opportunity to so unlimited subsidized searching of DIALOG databases. This first report from the project analyzes the vocabulary terms twenty-two scholars used in their natural language descriptions of their information needs and in their online searches. The data were extracted from 165 natural language statements and 1.068 search terms. Vocabulary categories used by humanities scholars were found to differ markedly from those used in the sciences, a fact that imposes distinctive demands on thesaurus development and the design of online information systems. Humanities scholars searched for far more named individuals, geographical terms, chronological terms, and discipline terms than was the case in a comparative science sample. The analysis provides substantial support for the growing perception that information needs of humanities scholars are distinct from those of scholars in other fields, and that the design of information-providing systems for these scholars must take their unique qualitites into account

    Abstract
    Web links have been studied by information scientists for at least six years but it is only in the past two that clear evidence has emerged to show that counts of links to scholarly Web spaces (universities and departments) can correlate significantly with research measures, giving some credence to their use for the investigation of scholarly communication. This paper reports an a study to investigate the factors that influence the creation of links to journal Web sites. An empirical approach is used: collecting data and testing for significant patterns. The specific questions addressed are whether site age and site content are inducers of links to a journal's Web site as measured by the ratio of link counts to Journal Impact Factors, two variables previously discovered to be related. A new methodology for data collection is also introduced that uses the Internet Archive to obtain an earliest known creation date for Web sites. The results show that both site age and site content are significant factors for the disciplines studied: library and information science, and law. Comparisons between the two fields also show disciplinary differences in Web site characteristics. Scholars and publishers should be particularly aware that richer content an a journal's Web site tends to generate links and thus the traffic to the site.

    Abstract
    The study set out to determine: (1) what were the searching characteristics of end-users in a non-academic environment and explain this in the light of their information needs; (2) whether these characteristics were those that were ascribed to end users in the professional literature; (3) whether they differed materially from those of information professionals working in the same fields. Searching characteristics were interpreted in their widest sense to include: command utilisation/knowledge; search success a satisfaction; volume of searching; searching style / approach; duration of searches; file selection; willingness to delegate and levels of training. These issues were explored in relation to 2 practitioner groups - journalists from he Guardian newspaper, and politicians from The House of Commons. Comparative data were also sought from information professionals in these 2 organisations. A mixture of social and statistical methods was used to monitor end-user and professional searching, though transactional log analysis was strongly featured. Altogether the searching behaviour of 170 end users was evaluated in the light of the searching behaviour of 70 librarians. The principal findings were that: in some respects end users did conform to the picture that information professionals have of them: they did seartch with a limited range of commands; more of their searches produced no results, and search statements were simplly constructed. But in other respects they confounded their image - they could be very quick and economical searchers, and they did not display meters of print-out. However, there were variations between individual end users, and it was often possible to find an end-user group that matched an information professional group on one aspect of online searching or another. The online behaviour of end users was very much related to their general information seeking behaviour; and to the fact that they were not trained

    Abstract
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
