'Tarot for yourself' - Mary K Greer
'Tarot your everyday guide' - Janina Renee - (interpreting cards in the 'advice' position)
'The Complete Tarot Reader - Everything you need to know from start to finish' - Teresa Michelsen
'The Tarot Revealed - A simple guide to unlocking the secrets of the tarot' - Paul Fenton Smith
Mary Greer's Complete Book of Tarot Reversals - excellent book. I have had it for a long time now and none of the other books I have come anywhere close to it.
I'd add to these Robert V O'Neil's Tarot Symbolism; Cynthia Giles, The Tarot: History, Mystery and Lore; Art Rosengarten's Tarot and Psychology; Mary Greer's Women of the Golden Dawn; Sandra Thomson's Pictures of the Heart: A Tarot Dictionary, Sylvie Simon's The Tarot, Art, Mysticism, Divination ... probably more - that's just off the top of my head. Phew! What a relief, they were getting heavy - huh! humour!
I would say the one that has help me the best right now is Teresa Michaelson's Complete Tarot Reader, Everything you need to know from start to finish. Is most definitely a must have, along with 78 Degrees by Rachel Pollack.
