In 1965, J. C. R. Licklider dedicated his book "Libraries of the Future" to Bush. Licklider wrote that he had often heard of the memex and "trails of reference", even before he had read "As We May Think". Also in 1965, Ted Nelson coined the word hypertext in a paper that quoted Bush's memex idea at length. In 1968, Nelson collaborated with Andries van Dam to implement the Hypertext Editing System (HES). In his 1987, book entitled "Library Machines", Nelson defined hypertext as "non-sequential writing with reader-controlled links". In 2000, Tim Berners-Lee published a statement, acknowledging the influence of hypertext, the work of Engelbart and Bush's "As We May Think" on the development of the World Wide Web. In 2003, Microsoft promoted a life-logging research project under the name MyLifeBits as an attempt to fulfill Bush's memex vision.
