- Abstract
- Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

- Abstract
- Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

- Abstract
- Although several attempts have been made to devise simplified shelf arrangements for children, little consideration has been given to developing a simplified automated library catalogue. At Denver Public Library in the USA a catalogue has been devised enabling users to search via graphical symbols. Results of research into children's use of library catalogues was used as a basis for creating the system. Librarians must be prepared to re-examine how far existing systems meet the needs of their users

- Abstract
- Prism is a retrieval system that provides an online catalogue for a collection of original cartoon drawings at the Univ. of Kent. The article starts with a general discussion of graphical user interfaces for retrieval systems and then describes the Prism sysem itself. Prism is unusual in that it has largely direct manipulation graphical user interface and also in that it stores and displays digitised images of the cartoon drawings along with conventional textual catalogue records

- Abstract
- Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

- Abstract
- A research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

- Abstract
- An online library catalogue served as a testbed to evaluate an interactive query expansion facility based on relevance feedback for the Okapi probabilistic term weighting retrieval system. The facility was implemented in a graphical user interface (GUI) environment using a game-board metaphor for the search process, and allowed searchers to select candidate terms extracted from relevant retrieved itms to reformulate queries. The take-up of the interactive query expansion option was found to be lower, and its retrieval performance less effective, compared to previous tests featuring automatic query expansion. Contributory factors including the number, presentation and source of terms are discussed

- PACE (Public Access Catalogue Extension) is an alternative user interface designed to enhace OPACs. PACE simulates images of books and library shelves to help users browse through the catalogue. Reports results of a study in which PACE was tested in a college library (Vanier College), in a real operational environment, against a second generation test based OPAC: Best-Seller. Results show that a simple browsable retrieval interface performed as well as a second generation OPAC in terms of retrieval speed and search success. The overwhelming majority of students, however, preferred the browsing capability of PACE through the familiar metaphor of books and library shelves to a text based OPAC

- 1. Introduction Significant research in the design and use of online public access catalogues (OPACs) has been conducted by professionals in library and information science (Borgman, 1996; Carlyle, 2001, Carlyle & Timmons, 2002; Hancock, 1987). However, only limited research has addressed actual library user interaction with and perceptions of online catalogue displays and bibliographic elements (Abrera, 1986; Luk, 1996; Markey, 1983). Retrieval systems, specifically online library catalogues, should consider user perceptions and expectations as an important aspect of design and implementation for improved catalogue efficiency (Hert, 1996). Therefore, it is necessary to examine the online catalogue from a user perspective to determine if it is currently succeeding in meeting the bibliographic needs of users in terms of description, display, navigation, and to provide principles for design of future OPACs. A study seeking to understand better how public library users interact with general OPAC displays and the more specific displays of bibliographic information was conducted in 2003. Research questions focused an 1) user perceptions of the OPAC, 2) the elements in a bibliographic display standing out as most important in selection and identification, and 3) user feedback an the process of using the OPAC. The purpose of this paper is to highlight the larger study findings having implications for future research and online catalogue design.
