Before I became a futurist, I spend some time at Stanford, working with the Buckminster Fuller collection. One of the things I worked on was digitizing the massive audio and video holdings, which consist of several thousand hours of Fuller's lectures, seminars, and other events.
Back then (in 1999 and 2000), digitizing the stuff looked really hard, and making it publicly available seemed pretty daunting. What a difference a few years make. Now, Stanford's put a big slice of the Fuller audio and video online. Really amazing stuff, particularly in the 1950s, when Fuller was in the habit of turning on a tape recorder when he thought he was doing something interesting, not just when he was about to give yet another lecture.
