My three favorite reference books on tarot, right now, are also books I'd happily recommend to any beginner:
Choice Centered Tarot by Gail Fairfield
It appears to be out of print, but her book, Every Day Tarot: A Choice Centered Book (ISBN: 1578632684) is the updated version and looks to expand on the ideas presented in the original.
This one's (I own the original, so can only comment on it) basis is in numerology, and the only close-to traditional meanings given are for the majors, but I find it quite helpful, and I use it with Marseilles and other non-scenic pip decks like the Crystal Tarot, as well as an adjunct to traditional interpretation. I've nearly worn out my copy!
The Complete Book of Tarot Reversals by Mary K. Greer
(ISBN: 1567182852)
You don't have to use reversals to get full benefit from this book. It gives you a good basis in Tarot, with fairly traditionally based interpretations. It's also terrific to have if you decide to take the plunge into reading reversals. I find the interpretations given to be quite insightful, and I like the "shamanic" meaning given at the end of each reversal interpretation.
Tarot As a Way of Life: A Jungian approach to the Tarot by Karen Hamaker-Zondag
(ISBN: 087728878X)
At first I didn't like this book, but the more I use it the more it grows on me, until it's become one of my mainstays. If there's one thing I still don't care for, it's that the author takes you on a sequential journey through the majors, and I've never liked the "Fool's Journey" type of interpretations that imply the lessons of the majors have to come in any particular order. But other people do like that, and this book has so much to offer in other regards, that aspect doesn't bother me much. I can take the meanings in any order I like, anyway.
