    Abstract
    Describes the history of the Univ. of Liverpool Research Group and its vision. The vision is to merge medical knowledge and hypermedia to produce more powerful information generation and improve access tools for those in health care. Like GALEN, the plan is to improve the construction of knowledge bases and provide user interfaces to medical information

    Abstract
    Investigates information-seeking tasks and associated cognitve issues in the context of interacting with an evolving collaborative hypertext. Fishexe view browsers were used to facilitate exploring in a large information space. The fishexe view browser was extended to incorporate word frequencies. The effects of the fisheye view browser and the changing document were tested with 2x2 factorial experiment. Multivariate tests founs a significant interaction between the 2 factors and a significant main effect of the fisheye view browser. The users who had access to the word frequency information performed their tasks more effectively than the users without access to word frequencies. This work implies that several aspects of an evolving hypertext might als be useful incorporated in an associated fishexe view browser

    Abstract
    The disciplines of human-computer interaction, computer-supported collaborative work, information storage and retrieval, and artificial intelligence should complement one another in the new discipline of hypertext. This holistic view of hypertext focuses on links: links within a document (microtext), links among documents (macrotext), links among people (grouptext), and dynamic links (expertext). The principles and systems which are relevant to creating and accessing hypertext can be usefully presented under the heading of text, microtext, macrotext, grouptext and expertext. From text to expertext, people consistently use hierarchical structures, particularly hierarchical semantic nets, to organize information

    Abstract
    Presents a study on hypertext examining the cognitive styles and spatial ability of users; the complexity of tasks; and the strucutre of information organization and the visualization of the structure. Future work on hypertext usability should emphasize task taxonomies along with longitudinal and ethnographic studies for a deep understanding of the interactions between users and hypertext

    Abstract
    The concepts of hypertext, multimedia and hypermedia are often confused, but can defined thus: hypertext is text with links, multimedia is synchronized media, and hypermedia is multimedia with links. Presents descriptions of systems for hypertext, multimedia and hypermedia. The computer storage and processing requirements for multimedia are orders of magnitudes greater than those for hypertext. Nevertheless, the hypertext model can be extended to deal with hypermedia by including multimedia synchronization capabilities. Information technology and its associated terminology should help people effectively compare experiences and thus have more influence on future developments

    Abstract
    The subject of this book is the relationship between people and interactive media. Written by one of the world's leading experts on this subject, this book explores how hypermedia, groupware, and networks change the way in which people, gropus and organizations work and interact. Its wide-ranging focus discusses the emergence of new technologies and demonstrates by considering real-life case studies the impact each has had on the way we view and interact with colleagues and information. With its emphasis on actual examples of usage, the author provides both practitioners and students with a fascinating glimpse of the future of these media and their applications.
