Richard,
As for the computer, I read something by him that said when he switched from typewriter to computer, his books all got thicker. Typewriters (for you young pups) required thought, because they didn't have copy and paste, and only the last generation of them had a delete that worked. You typed, and if you made a mistake sometimes you'd have to retype the entire page! They required more discipline than word processors.
I remember attending a WorldCon panel some 15-20 years ago that Glen was on. He said he could walk down the aisle at a books store and know which ones were written on a computer. They were all the really thick ones and he didn't have a very high opinion of them. Seems he hasn't kept to his own advice. -- Eric Herrmann <shpshftr@xmission.com>
