Microcosm (hypermedia system)

Microcosm was a hypermedia system, originally developed in 1988 by the Department of Electronics and Computer Science at the University of Southampton, with a small team of researchers in the Computer Science group: Wendy Hall, Andrew Fountain, Hugh Davis and Ian Heath. The system pre-dates the web and builds on early hypermedia systems, such as Ted Nelson's Project Xanadu and work of Douglas Engelbart.
