- Abstract
- Describes the background to a research project being undertaken at Charles Stuart University, New South Wales. The project entitled 'Using graphic displays to build mental models for effective subject searching of the online catalogue' investigates a method for enhancing the user's understanding of the subject access system of an online catalogue to improve searching performance. Discusses the rationale and theoretical framenwork for the study, considers the application of mental models theory to the research project and visualization in information retrieval, and examines related research and what is known and unknown about the topic

- Abstract
- Browsing is an important aspect of the information-seeking activities of library users and is primarily visual. Second-generation OPACs lack the necessary visual characteristics for browsing. These characteristics may be best implemented through simulation of images of books and library shelves on the computer monitors. To mimic users' mental models of the real world may be costly, however, unless new interfaces can tap into existing sources of information. A possible solution may be found in using the information embedded in the MARC record pertaining to the physical description of a book. Public Access Catalog Extension (PACE) is designed as an alternative interface based on mental images of users and MARC records

- Abstract
- Identifies 6 types of searches on the basis of paudsing behaviour by using cluster analysis. The 6 types of search were highly associated with search fleuncy and the construction of a mental model. Examines learning during multiple searches on the basis of the 6 types. Finds that searchers gain more experience, increase their searching proficiency and become more fluent at searching while online. The changes of search level in multiple searches showed that most searchers moved towards greater fleuncy

- Abstract
- This paper describes a new OPAC system called The Book House and discusses its relevance as a solution to current OPAC developments. The Book House is an interactive, multimedia, online public access catalogue system designed to support casual and/or novice end-users in information retrieval. It runs on a Macintosh and is available on CD-ROM and disks in English and Danish (it can be purchased from Risø for $100). It comprises an interface and module for classifying and indexing fact and fiction books in the database called Book House Write. It uses icons, text and animation in the display interface in order to enhance the utility of the system for the general public. Both words and pictures can be used for searching, which makes the system suitable for all age groups. It plays on users' previous experiencees with computer games to support learning by doing something in an enjoyable way. A prerequisite for the design of The Book House was a new approach to cognitive analysis of retrieval in libraries. Based on the success of this approach, it is claimed that OPAC systems will only be really useful and widespread (1) when their domain and task characteristics allow supplementary information to be added to existing descriptions of book content in online card catalogues in order to match end-users' intentions and needs, and (2) when the user interface and routes to the databases are configured as an integrated and uniform set of displays which match the search strategies of users, as well as their mental capabilities and limitations

- Abstract
- Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction

- Abstract
- The chapter deals with methods of subject cataloguing, subject analysis and representation of library materials and outlines the practice of subject searching in library catalogs after the introduction of online catalogs. The vocabulary control methods in the Library of Congress Classification and LCSH are described and strategies for the use of theses systems in online retrieval situations are outlined

- Abstract
- Examines the advantages and disadvantages of precoordinated, postcoordinated and automatic indexing with regard to existing information storage systems, such as card catalogues, OPACs, CR-ROM databases, and online databases. Presents a general model of document content representation and concludes that the library profession needs to address the development of databank design models, relevance feedback methods and automatic indexing assessment methods, to make indexing more effective
