Wired had a long but interesting article about Xanadu back in 1995: http://www.wired.com/wired/archive//3.06/xanadu.html?person=... In many ways the story of Xanadu is sad and depressing.

Of course, Xanadu is (or would be) a digital remake of Vannevar Bush's memex: http://www.theatlantic.com/doc/194507/bush Frankly, I'm not sure Ted Nelson has added much to the original concept with Xanadu.

You can download Xanadu(R) Space(TM), a user interface demo, from here: http://xanarama.net/ Windows only, but I got it to work in WINE. Ted Nelson really likes his trademarks, probably because it's as tangible as Xanadu has become after 40 years.
