    Abstract
    In many hypertext systems authors are encouraged to create hierachical structures, but when writing, the hierarchy is lost because of the inclusion of cross-reference links. Looks at ways of recovering lost hierarchies and finding new ones, offering authors different views of the same hypertext. Identifies properties of the hypertext document. Develops multiple metrics including compactness and stratum - compactness indicates the intrinsic connectedness of the hypertext, and stratum reveals to what degree the hypertext is organised so that some nodes must be read before others. Uses several exosting hypertexts to illustrate the benefits of each technique. The collection of techniques provides a multifaceted view of the hypertext, which should allow authors to reduce undesired structured complexity and create documents that readers can transverse more easily

    Abstract
    Increased enrollments, changing student expectations, and shifting patterns of Internet access and usage continue to generate resource and administrative challenges for colleges and universities. Computer center staff and college administrators must balance increased access demands, changing system loads, and system security within constrained resources. To assess the changing academic computing environment, computer center directors from several geographic regions were asked to respond to an online questionnaire that assessed patterns of usage, resource allocation, policy formulation, and threats. Survey results were compared with data from a study conducted by the authors in 1999. The analysis includes changing patterns in Internet usage, access, and supervision. The paper also presents details of usage by institutional type and application as well as recommendations for more precise resource assessment by college administrators.
