The Book of Werewolves: Being an Account of a Terrible Superstition, Paperback/Tarl Warwick

This work is one of the finest ever penned on the subject of lycanthropy and werewolf lore. Written in the mid 1800s by the rather eccentric Sabine Baring-Gould, it covers more than 1,000 years of lore from a half dozen paths- the berserker of Norse lore, French mythology, and then-modern anecdotes of cannibalism and madness. Not relegating the werewolf just to a secular and skeptical study, nor simply to spiritual banter, Baring-Gould manages to compress an enormous span of historical material into his work; a work which is no doubt of value to the academic and those involved with the occult at the same time.
