I thought I had posted a bunch of the books I own, but I can't find it now. These are the 4 that are quick to get to at the moment:
Cardology The True Meaning of the Cards by M.F. "Chance" Wyatt
The Message: Your Secrets in the Cards by Deborah Leigh
Playing Card Oracles by Ana Cortez & C.J. Freeman
Sabian Symbols in Card Reading by Delle Fowler
No, I don't like sticking with one method.
On his site, Kapherus has these starred as highly recommended:
IT’S WRITTEN IN THE CARDS by Leo Louis Martello
CARD READER’S HANDBOOK by Regina Russell
Other authors are Marthy Jones, Joanne Leslie, Jane Lyle, Sophia, Chita St. Lawrence, Richard Webster, Louise Woods
