"Witchcraft Out of the Shadows" begins with a survey of historical influences from classical times, northern European paganism, and medieval and early modern Europe. It then describes the roots of modern neopagan witchcraft in groups such as the Hermetic Order of the Golden Dawn and individuals such as Aleister Crowley and Doreen Valiente. Particularly important is the critical analysis of the claims made by Gerald Gardner about Wicca, as well as a detailed discussion of the liturgical content of Gardner's "Ye Bok of Ye Art Magical" and its sources.
