Wondering if there is any good book for Pot Limit Omaha? Have been looking around for some and have not found any.

Note: While primarly concerned with PLO, I am willing to purchase a book with both PLO and O/8, prefer a book dedicated to Pot Limit Omaha only.

There is very little work on this subject. The best work on this subject is by far and away Omaha Hold'em Poker by Bob Ciaffone. With that you should get Pot Limit and No Limit Poker by Bob Ciaffone. Next on the list would be SSII.
Must buys for PLO:
1. Theory of Poker
2. Omaha Hold'em Poker
3. Pot Limit and No Limit Poker
4. Super System II

Other great books that will help
1. Improve Your Poker
2. Championship Omaha
3. How Good is Your Pot Limit Omaha (A book that is more relavent to high stakes games, in Q/A format)-only book I know of that covers PLO only

I've responded to this question about 20 times on this site, and I'll stick to my answer. If you are learning Omaha, there's no better book than TJ Cloutier's "Championship Omaha."

It's got sections on PL Omaha, Limit High Omaha, and Limit Omaha 8/better. It teaches you to play tight and only draw to the nuts.

The biggest thing I took from it when I was learning Omaha was hand selection. to an Omaha novice every hand looks like it can be a winner. But once you learn the game you realize there's a reason you don't play a hand like A 6 K 9 in a full ring game - 'cause it's not likely a winner. Seriously pick up this book, and it will improve your fundamentals.

I like Omaha Hold'em better than Championship Omaha. It's short, but sweet and kind of hard to find. I got mine from the gambler's book shop.
