To be honest with you some of them I have already read but just wanted to have them in hardcover.
Harrington on Online Cash Games is just a perfect book if you are getting serious about online, in my opinion it's like a must-read!
Small Stakes Hold'em - the same thing but only for FL!
Poker Essays - just not worth it...
This time I ordered The Intelligent Poker Player & Analytical No-Limit Hold ’em... didn't really have time to read them but I skimmed through them, they look like some serious sh**, will get to them in a couple of weeks when I have time.
About the quality of the books: average, don't like the paper but the bonding is solid and they all have the same smell that just gets me going every time
I would also advise you to get a shirt as they are really just top quality!
