“…Like those on the hypermedia system for learning, studies on hypermedia for information retrieval have engendered inconsistent findings. Several studies found that using a hypermedia system resulted in better search performance than using other nonlinear information systems (Egan, Remde, Landauer, Lockbaum & Gomez, 1989;Gary & Shasha, 1989;Leventhal, Teasley, Instone, Rohlman, & Farhat, 1993), whereas others found the opposite (Marchionini & Shneiderman, 1988;McKnight, Dillon, & Richardson, 1990). This inconsistency in findings might have been due to variables other than the hypermedia technology, such as differences in users, tasks, and so on.…”
