"Wholly new forms of encyclopedias will appear, ready made with a mesh of
associative trails running through them, ready to be dropped into the
memex and there amplified. The lawyer has at his touch the associated
opinions and decisions of his whole experience, and of the experience of
friends and authorities. The patent attorney has on call the millions of
issued patents, with familiar trails to every point of his client's
interest." - Vannevar Bush, As We May Think

Bush was such a visionary it amazes me every time I reread this seminal piece. He also describes a mini-camera (to be worn on forehead) that could record anything "worthy of the record." Sorta reminds you of the teensy little phone cameras, doesn't it?
