We carry several good beginning stone carving books: Donna Meilach's Contemporary Stone Sculpture and Milt Liebson's Direct Stone Sculpture. Both are excellent. Read them cover to cover.
For figure carvers, we have Philippe Faraut books about clay. The photographs of figures are priceless and good lessons in anatomy.
Creating with Soapstone by Kurt Haberstich is a classic. It is out of print, but we have a few copies.
