Harrington on Holdem 1 & 2, Negraneau's book but only the smallball section the rest is "erm", The Mental Game of poker or the other book with the same stuff in (the poker hero). Schoonmakers books are good for psychology. John Vorhaus gave the idea of Little Poison in one of his many books. I've just counted my books on poker and have 330 of them all of which I've read. Lee Jones Low Limit Holdem is probably the best for micro stakes fixed limit cash games moving onto the Ed Miller & Sklansky micros one as you move up. There's a lot not worth reading as well though. I've read both the Supersystems but they are outdated but are good for the "other" games. Hope that's some help
