Pooling of Knowledge: By pooling information in a massive digital knowledge base, systems such as Xanadu will permit the user to combine, fragment, manipulate, and disseminate information resources in a form that is most appropriate to the context of need and application. The hypermedia systems of the future will represent a pooling of knowledge not only in a common media format, but as a global information network that is constantly updating and validating information content and use. A self-informing capability will expand not only the content of the information base, but also the associative structure with each user interaction. The software interface and programming shell of hypermedia systems will be modular constructs that will not require sophisticated programming skills, readily permitting user modifications in response to particular needs Alan Kay, a key developer of the Xerox and Apple Computer innovations in computer systems, has asserted that the ultimate goal "is in letting ordinary people make tools for themselves" (Kay in Rogers, 1988). Interactive hypermedia systems will become "virtual reality" workstations that combine computers, holography, 3-D animation and video sources, and audio to simulate the objects, tasks, tools, and machinery of a user designated environment. Computer models that simulate material conditions will sharpen diagnostic skills. Networked hypermedia systems will allow on-line consultations and the exchange of expertise in the preservation decision process, allowing a broader application of knowledge to preservation problems. Continuing education for professionals will be based on individual interactions with a thematic information base, allowing professionals to stay abreast of developments in particular areas of interest. The place of learning will be increasingly important, as computer miniaturization will make hypermedia systems transportable, permitting the computer to accompany the user to the best environment for assimilating the designated skills or knowledge.
