- Abstract
- Analyses the OPAC at the Australian Catholic University in New South Wales, Castle Hill Campus using an object oriented model following Rumbaugh's methodology, as described in 'Object oriented modelling and design, 1991'. The process of analysis, although difficult, is one of the most effective ways of determining each function of a system of this kind. The methodology is especially useful as the data structure, behavioural and functional aspects of the system are displayed in separate diagrams. This is an advantage for those analysing systems, who can display many factors without confusing different aspects involved in the analysis process

- Abstract
- One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.

- 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
- 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
- A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

- Abstract
- Reports on a study at an elementary school in Washington, DC examining pupils' use of an OPAC. Presents this within the overall instructional environment of the school in order to open a window on the broader interaction of children, technology, curriculum, instruction and learning. Explains the methodology used in the study, the findings of the study, and notes a number of conclusions. Focuses in particular on the patterns of success and failure of children's use of the OPAC, their search strategies and the nature of their interaction with the OPAC

- Abstract
- Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

- Abstract
- Different users of a Web-based information system will have different goals and different ways of performing their work. This article explores the possibility that we can automatically detect usage patterns without demographic information about the individuals. First, a set of 47 variables was defined that can be used to characterize a user session. The values of these variables were computed for approximately 257,000 sessions. Second, principal component analysis was employed to reduce the dimensions of the original data set. Third, a twostage, hybrid clustering method was proposed to categorize sessions into groups. Finally, an external criteriabased test of cluster validity was performed to verify the validity of the resulting usage groups (clusters). The proposed methodology was demonstrated and tested for validity using two independent samples of user sessions drawn from the transaction logs of the University of California's MELVYL® on-line library catalog system (www.melvyl.ucop.edu). The results indicate that there were six distinct categories of use in the MELVYL system: knowledgeable and sophisticated use, unsophisticated use, highly interactive use with good search performance, known-item searching, help-intensive searching, and relatively unsuccessful use. Their characteristics were interpreted and compared qualitatively. The analysis shows that each group had distinct patterns of use of the system, which justifies the methodology employed in this study
