Multimedia authoring and publishing incorporates a variety of types of publications, from newly created multimedia presentations to digital libraries that incorporate a wide variety of pre-existing materials, from small self-published magazines to large productions that involve dozens or hundreds of workers and budgets nearing those of small feature films. In this paper, we consider an important form of electronic publication that is not frequently analyzed: the lecture, as reproduced and extended electronically.We present a methodology for transforming a recorded lecture into an appropriately useful and interactive multimedia publication—the hyper-reproduction—highlighting techniques appropriate for publications with limited resources (workers, time, bandwidth, etc.). We suggest techniques for automating parts of the construction and discuss the added capabilities of such reproductions and their effect on how users access, navigate, and retain information.
