Ok, I went looking for a specific book on Amazon (wanted to put a link to the Chomsky stuff I'm reading). Three books later, I finally pulled myself away. I can't stop at Amazon without buying something. Tonight's purchases include the Joseph Campbell biography and his book Tarot Revelations. I had no idea Campbell wrote about the Tarot. I've been a big fan of his "Power of Myth" stuff since a professor introduced me to it about 15 years ago. I've been interested in the Tarot longer than that.
For those new to the Tarot, I'd suggest the Marseilles deck or the ever-popular Rider-Waite deck. Even if you don't believe in the fortune-telling aspects, examine the symbology. Tarot contains symbols from the earliest civilizations and represents many of the universal spirtual aspects of Mankind.
