Expertise: The highest level of understanding information is characterized by what Neil Larson terms "theological" expertise (Neil Larson: oral communication on 12/7/88). This level of expertise acknowledges the ability of an expert to cite the sources of relevant knowledge, the equivalent of citing the chapter and verse of Biblical quotations. However, the objective of the hypertext strategy is not to commit the information base to rote memory. Instead, hypertext systems are intended to emulate the associative relationships that constitute the knowledge networks in the human brain, providing efficient access to relevant information paths that can be navigated according to the particular context of user needs. Knowing a subject area well enough to recall the file, node, and line location of desired information may facilitate the retrieval of information, but it does not represent a substitute for the knowledge processing and synthesis essential to the decision process. As a consequence of the essential interactivity between the user and the information network, and the context sensitivity of the information retrieval process, hypertext systems can radically change the value and usefulness of the information that constitutes the knowledge base.
