*Tarot Symbolism ... Bob O'Neill, is arguably the best tarot book ever.
*Forest of Souls, already mentioned was a wonder.
*Cynthia Giles, The Tarot: History, Mystery & Lore is a special favoutire of mine.
*Kaplan's Encyclopedia's
*Richard Cavendish's The Tarot was the first to show me what a tarot book could be like.
*Wang's Qabalistic Tarot.
*Art Rosengarten's Tarot and Psychology, if you are that way inclined.
*Add to that Wheel of Tarot, A Tarot Anthology Eds. James Wanless and Angeles Arrien. The introductions to each of the papers presented are woeful, but the papers themselves are fascinating.
*And not Tarot, but essential reading (imho) Psychology and Alchemy by Jung.
*Just have to add Mary Greer's Women of the Golden Dawn ... it was superb.
