History of the Xanadu® Projects
***to be written
Nelson's 1982 Datamation article A New Home for the Mind.
Many people made many contributions over the years. Here we attempt to give credit for the major conceptual or technical contributions to Udanax Green & Gold, but the long years make memory unreliable. If you know of a contribution you feel we should have included, please let us know. We probably just forgot, and you have our apologies. (We also intend to acknowledge other forms of contribution eventually.)

Systems Inspired by Xanadu®
The most important of the systems inspired (or partially inspired) by Xanadu® is, obviously, the World Wide Web -- the medium on which you are presently reading these very pages. The 1989 document Information Management: A Proposal is one of Tim Berners Lee's earliest records of the birth of the web.
