Abstract

Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

Abstract

An ongoing thread in information retrieval research has been the exploration of user goals (or information needs, or problems) on information retrieval systems. It has been suggested that an understanding of goals and their role in the information retrieval interaction can provide insight into appropriate retrieval strategies, relevant documents, and general system design. This article reports on empirical findings concerning goals of users searching an OPAC at a northeastern United States university. These findings were generated during a large inductive and qualitative study of users' interactions with the OPAC. It was found that respondents came to the OPAC to search for a variety of course- or degree-related projects in which they were engaged. Respondent goals were not greatly modified during the course of these interactions. A set of situational elements associated with the respondent's goal was also identified. The implications of these findings for OPAC design and the training of informational professionals are discussed

Abstract

Presents some results from research into the uses and usefulness of electronic bibliographic databases in academic contexts, carried out as part of a British Library funded research project. Ethnographic and focus group data was gathered initially in 3 departments (natural science, social science and humanities) at the University of Kent at Canterbury covering all academic staff, researchers and postgraduates. This was then expanded to postgraduates and staff in the same 3 disciplines at other universities. 5 themes from this research are outlined: who uses the system, who does not, and where are these activities and inactivities happening; where does formal training occur; and where does learning occur. The problems of interface between computer systems and users often mirrored that between library enquiry staff and users where users did not know to frame questions and the advice given was not in a form understood by the users

Abstract

This article describes the findings of a research project that tested a new subject-access design in an experimental online catalog that had a wide range of subject-searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Library users at 2 academic libraries searched this experimental catalog for topics of their own choosing, judges the usefulness of retrieved titles, and answered post-search questions about their searching experiences. Mixed results from a quantitative analysis (i.e., precision scores) were supplemented with the more conclusive results from a qualitative analysis (i.e., failure analysis). Overall, analyses demonstrated that the new subject-access design that featured search trees was more effective in selecting a subject-searching approach that would prooduce useful information for the subjects users seek than users would select on their own. The qualitative analysis was especially helpful in providing recommendations for improving specific subject-searching approaches to increase their effenciency, increase user perseverance, and encourage browsing. It also suggested enhancements to the new subject-searching design to enable systems to respond to the wide variety of user queries for subjects

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
