Book Advice

[chipolino]

Here are the books I got so far:
Small Stakes Hold'em; Internet Texas hold'em

Books coming in the mail:
Winning Low Limit Hold'em; Hold'em Poker for Advanced Players; Theory of Poker

I need a NL tournament book but I need advice on which one:
Harrington on Hold'em vs Tournament Poker for Advanced Players

Also, is this book worth getting: Middle Limit Holdem Poker by Bob Ciaffone

Any suggestions are very appreciated.
