When asked what books on poker he preferred, Paul responded with a list from his personal poker library, and gave some comments on each:

Caro's Book of Tells,  by Mike Caro.  Originally published in the early 80s,  having to do with the  "tells"  to look for  --  unintended body language that people exhibit when holding certain hands.

Play Poker Like the Pros,  by Phil Hellmuth, Jr.  Covers a variety of poker games with general strategy by the 1989 World Champion.  Big on content,  but not on depth.

Seven Card Stud for Advanced Players,  by David Sklansky,  Mason Malmuth and Ray Zee.  A good book on 7-stud,  but geared for more high stakes games.

7 Card Stud: The Complete Course in Winning  by Roy West,  columnist for Card Player magazine.  Geared for lower and medium stakes games.

How to Beat Low Limit 7-Card Stud Poker  by Paul Kammen.  (I have to have my own book in my library, right? :o)

Tournament Poker for Advanced Players  by David Sklansky.  A good guide for finding success in tournaments,  which differ from regular games.

Super System and Super System 2  by Doyle Brunson with contributing authors.  Covers the common poker games.  Volume 2 makes some updates,  especially to limit holdem,  and has some added tips from Mike Caro.  Considered by many to be "The Bible" of poker.

The Theory of Poker  by David Sklansky.  A poker classic which covers concepts to success in poker, as opposed to being a guide about games  --  concepts include check-raising,  semi-bluffs,  pure bluffs,  deception,  etc.

High Low Split Poker for Advanced Players  by Ray Zee.  A good guide to Omaha High-Low and Seven Card Stud Eight-or-Better,  but a bit too brief and geared for higher stakes games.

Small Stakes Hold 'em: Winning Big with Expert Play. By Ed Miller,  David Sklansky and Mason Malmuth.  The best book on small stakes hold 'em games,  but it assumes that the reader is already a player so not an intro book.  Fantastic in-depth analysis of key concepts,  especially on the flop and the turn.

Winning Low Limit Hold 'Em  by Lee Jones.  A fantastic guide to success at low-stakes hold 'em games,  and good for the novice hold 'em player.  Not as in-depth as the Miller book,  but very helpful.

The Biggest Game in Town  by A. Alvarez.  A gem of a book and a great read about the world of high-stakes poker in 1981 Vegas.

Hold 'em Poker for Advanced Players  by David Sklansky and Mason Malmuth.  A good book on hold 'em,  but not for the small stakes player.  This book has helpful concepts but they do not always work at low stakes games.

Hold 'em Poker  by David Sklansky.  An introduction to holdem poker,  notable for the  "Sklansky hand rankings"  charts.  A short,  quick read.
