I honestly don't know on what basis all of these authors were released by NCP. But if you are in the market for some reading you might want to take a look at some of their websites, and some of their books available elsewhere. Just a suggestion :) I don't have links for them all yet and am not 100% sure some of the links are right but I will tidy this up as I go. If you know a link for one of them feel free to drop it on me via a comment. Just spreading some author love. If we can get a good, accurately-linked list, even if it doesn't sell books it might give their Google pagerank a little pick-me-up.
