Evolution of Hypertext:

The demonstration of a prototype "Memex" system by Doug Englebart
of Stanford Research Institute in 1968 was the catalyst that
prompted much of the contemporary development of the hypertext
concept.  Significant developmental research was initiated at
Xerox PARC, Carnegie-Mellon University, Brown University,
University of North Carolina (Chapel Hill), Tektronix Corp., and
Symbolics Corp. (Smith and Weiss, 1988).  The systems development
activity has accelerated dramatically in the past 5 years, as the
significant advancement of computer hardware technology
(particularly with regard to processor chips and storage systems)
has made the implementation of a viable hypertext system finally
possible not only on main frame processors, but on microcomputers
as well.  A number of these hypermedia systems are currently
available as programming shells which can be tailored to meet the
particular structural demands of specific information management
applications.  The Memex concept of Vannevar Bush has finally
reached the desktop, and it holds promise for resolving the
paradox of the information revolution.
