From H. G. Wells’ lecture on Brain Organization of the Modern World, October and November 1937.
“This Encyclopedia organization need not be concentrated now in one place; it might have the form of a network. It would centralize mentally but perhaps not physically. Quite possibly it might to a large extent be duplicated. It is its files and its conference rooms which would the the core of its being, the essential Encyclopedia. It would constitute the material beginning of a real World Brain.”
“….In a few score years there will be thousands of workers at this business of ordering and digesting information where you now have one.”
This seems like a foreshadowing of hypertextuality to me.
