a couple books i picked up today

I went to the library today and picked up a couple books and was wondering if they're worth reading. I've been playing since December I had never played a hand before that and I've read Phil Gordon's little green book and the first book of harrington's on hold em. To be blunt I was wondering if these will help me improve my no limit game. I figured a few of you have read these books and could tell me if they were beneficial to you or not.

The Theory of Poker by David Sklansky

No Limit Texas Hold'Em by Brad Daugherty & Tom McEvoy

Dont know about McEvoy´s book since i havent read it but im a couple pages in to TOH and so far so good.
His playing and writing style differs a lot from both Gordons and Harington´s but so far i like the book,but like every book u read u shouldnt be trying to copy there style but rather try to atopted some of the advice to your own playing style because poker cant really be played completly by the book,since the exact same situation cant be played "right" in a dozen diffrent ways.

What games are u playing mostly? Since that obvs. changes if a book can be helpfull or harmfull for your game since there is no use taking a book like FTP tournament strategy guide and try applying it to cash games or read HOC and try its addvice in a SNG since these books are written for certain playing forms and there for mostly apply just for that form.

I play mostly SNGs and Tournaments. I also play cash games but not often I haven't been able to find much reading for them. Could you recommend any books for cash games?

I have mostly read tournement based books so im not the best person to give addvice on cash game books but if heard that Harington on Cash and Professional No limit Hold´em are good

I have read Phil Gordon's Little Green book, and I have found it to be helpful to my game. You may have to read it more than once to fully understand all the concepts presented (I did). Phil Gordon's Little Blue Book is also a helpful and should be read after the green book.

Theory of Poker is considered one of the best (if not THE best) foundation books ever written. It will teach you such a base level of the purpose behind poker math and concepts. However, I found it tougher to read as well. It's thick, so for a begining player it may be tough to retain.

Harrington on hold'em is excellent (both his cash game and tournament series), as well as Gordon's books. Yet for understanding the game I still think Ed Miller's Small Stakes Hold'em is one of the best. It's a limit game book, but for understanding math, aggression, the board, and hold'em in general, it will teach you tons. His NL book is great as well.

You always have Daniel N's books for quick 'snippit' reads, and Gus Hanson's All Hands Reveiled is also very nice. But if you want true foundation books for the game and theory of poker in general, Sklansky, Miller, and Mason Malmuth (sp) is still the top of the order.

P.S. An attempt to understand any one of these books with a single read is next to impossible imo. Reread and get on the tables, best way to learn.
