| Abstract: | Hypertext is a computer technology for “nonsequential reading and writing” in which chunks or nodes of information are connected by fixed links. Users access hypertext by selecting cross-reference (or “buttons”) in the context of a given node that is connected via links to other nodes. Such an “associative” strategy for information storage and retrieval differs from the indexing and searching technology of conventional database management and text retrieval systems, and offers significant advantages when used instead of or in combination with search systems. Hypertext is an ideal medium for making job aids, reference materials, and ‘just in time training’ available online to information-based workers. This article reviews five commercially available hypertext systems, and discusses several key hypertext design issues. Among the most important of these issues are the critical role of navigational aids in preventing users from becoming “lost” in the hypertext, the application of structured writing techniques to hypertext development, and the potential contributions of the human performance technology approach to hypertext in the form of systematic analysis, design, and evaluation methods. |
