    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
    This paper presents a framework for design of work support systems for modern, dynamic work environemnt in which stable work procedures are replaced with discretionary tasks and many action possibilities are available to the user. In this situation, classic task analysis is less effective and a framework is therefore presented for work analysis, separating a representation of the work domain, its means and ends, its relational structure, and the effective task strategies among which the user may choose, from a representation of the users' general background, resources, cognitive style and subjective preferences. The aim is to design systems for information seeking in complex work domains characterized by rapid changes in users' information needs that leave the freedom open to a user to choose a task strategy that suites the user in the particular situation. An important feature of this approach is a human-work interface with a transparent presentation of the action possibilities and functional/intentional boundaries of the work domain relevant for typical task situations and user categories. This is illustrated by examples from 2 different domains that merge the cognitive engineering approach with information science disciplines: the library domain, and information seeking in the engineering design domain using the Internet
