I just wanted to give you all a few choices that you might want to work with when learning tarot or even sharpening your reading skills. Personally, I think that the more you know, the richer your readings can be.
My personal favorite tarot books at this moment are:
Another great online resource is Biddy Tarot. This page is chock full of information about working with the different cards from the Rider Waite Deck.
Working with any one of those books, or a combination, will give you a great foundation of knowledge to help with your card interpretations.
No matter what any book says, remember to allow your intuition to have free reign in deciphering the meanings of cards. Oftentimes, intuitive knowledge will be something that is triggered by the image on the card, and not related to the “classic meaning” of the card.
