Guiley, author of the previous edition and many other books on occult and New Age topics, covers both historical witchcraft (particularly the witch trials of Reformation Europe and Colonial America) and contemporary witchcraft and Wiccan and pagan practice in over 500 detailed, clearly written, alphabetically arranged entries of various lengths. The second edition incorporates new historical research on the origins of witchcraft and updates and expands coverage of the modern revival, its most influential leaders, the organizations, and their practices.
