The excellent Open Culture Web site has posted "Everything I Know," 42 hours of lectures by Buckminster Fuller. (I have an interview of Fuller by RAW that I will post when I manage to find time to transcribe it.)
Pipzi Williams chips in with a haiku:
bucky fuller spoke
and other dimensions leaned
to listen closely
UPDATE: In the comments, Bogus Magus notes that transcripts are available here. I'll be loading some into my Kindle.
