Suggestions for becoming a better player

[keats]

I play 3/6 as my game. I have only read the Super System 1 and 2 sections on limit poker. I have adjusted these and now play a very tight style of poker. I am just interested in becoming a better player. I do not know the math of poker very well or really understand how one figures EV. I know that Theory of Poker is good for these but what I was wondering is if anyone could provide other sources for Limit Poker. If you are going to be a jackass and respond with google it please dont respond. I have already googled it and I'm sure of the 100,000 poker books out there these days there are some that poeple with recommened. I am looking for books that you feel have made your game better.
