those are a few of my favs of the old school, I also love Niven, and John Varley, Philip Jose Farmer, Robert Anson Wilson (although that isn't so much sci-fi) and a number of others... but I was trying to find the first short novel in Stephen Donaldson's Gap Series Called "The Real Story" which, honestly, I feel that series is nearly as good as any other sci-fi series I have read... definitely as good as Herbert's Dune series. I have all the other volumes on paper, but lost the first short novel and could not it anywhere but in this huge collection.
