    Abstract
    Models administrative and operating costs surrounding a hypermedia database and determines 7 conditions for the cost justification of hypermedia; higher linking costs proportionately reduce the total number of links implemented; increasing the benefits from using the database increases the total number of links proportionately; increasing database size results in an increase in the total number of links implemented; if the database user learns from the database slowly, then a larger number of links need to be provided: the maximum size of databases which is justified on cost will increase as the average cost of linking each node becomes smaller; the total benefit from usage required in order to cost justify a database will decrease as the average cost of linking each node becomes smaller and the maximum size of database which is cost justified will increase rapidly as the learning rate increases. The learning rate can be increased by construction of links and nodes so that they are maximally informative

    Abstract
    Presents a 3 facet adaptive authoring model for online hypermedia information systems. It provides spatial reconfiguration of the presentation objects based on activation frequency, information content customization based on author specified criteria, and hypergraphic network optimization based on usage. Discusses the theory underlying the model, its architecture and hypermedia structure, and provides a preliminary quantitative measure and evaluation of its impact on authoring time, as well as study time

    Abstract
    Describes a hypermedia application that provides students reading German texts with advance organizers in the form of a movie clip designed to facilitate global comprehension and glosses for words in the form of text, graphics, video, and sound. Results of testing indicate that studuents not only reported the photograph and movie links as most helpful for learning vocabulary, but in fact chose them more than text. Performance on vocabulary tests showed that when links were accessed, words were recalled correctly approximately 75% of the time. Learner behaviour data showed that so called visualizers and verbalizers performed equally well on the vocabulary tests but accessed different modes of information (links) corresponding to their respective cognitive styles

    Abstract
    Presents a model of hypermedia that allows the combination of 'hyperstructured' information with dynamic multimedia information. The model is derived by extending the Dexter hypertext reference model and the Centrum voor Wiskunde en Informatica Multimedia Interchange Format (CMIF) multimedia model. Explains how the CMIF multimedia model builds on the model provided by Dexter. The Amsterdam hypermedia model enables the description of structured multimedia documents, incorporating time at a fundamental level and extending the hypertext notion of links to time-based media and compositions of different media

    Abstract
    Provides a quick overview of the historical development of hypertext/hypermedia, and the role of hypermedia in today's dynamic information environment. Actual R&D examples in both PROJECT EMPEROR-1, specifically its hypermedia R&D component experimented on all major delivery system platforms, is discussed and demonstrated, and new opportunities for libraries in the 1990s are further elaborated.

    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
    Discusses the concepts of multimedia and hypermedia. Introduces 2 additional multimedia types; computational and directive. These depend on direct interaction with the end user and increase the use of computing facilities within hypermedia presentations. The recognition of interactive media types provide fertile ground for new classes of hypermedia link types. Offers examples from prototype hypermedia systems for maths education and electronic news delivery to illustrate the application of these additional media types
