README.DOC, a Pennsylvania-based computer book discounter, sells their books at a 25% discount. $2 for S&H, though if you buy 3 or more books at a time they waive shipping charges as well. They have Applied Cryptography in stock. 800-678-1473. I also asked about Intro to Komolgorov Complexity; they don't stock it. I forgot to ask about Koza's Genetic Programming. - John
