Louis, Wen, Greer, Pollack - excellent advice. If you build up a tarot library, they are your cornerstones. (I didn't read Huggens but heard her book often recommended).
I have always like Greer's Tarot for yourself and Nina Lee Bradens Tarot for Self Discovery. Greer lets you discover the world of tarot, the world within you, and how the two are intertwined. I use some of her techniques and creative ideas still.
And Braden (whose book I don't have but I was a member of her mailing list ages ago and did many of her exercises) taught me to use the cards not only to pull them for divination, but to pick them to explore yourself.
Both empower you to treat the cards in an individual and intuitive way - without forgetting the strong foundations on which the tarot is built. I always feel I need both.
