Martin Gardner: Aha! Gotcha

Comments: Although not a magic book, many of the concepts in Martin Gardner's mathematical recreations books can be used for magic patter and ideas. For example, in Tom Craven's Lecture Notes, "Magic You Can Do", he turns the topical puzzle "The Vanishing Leprechaun" (page 67) into a magic trick.
