A lot of folks think that the only books on witchcraft worth reading are published by Llewellyn Worldwide. I am here to tell you such is not the case because there are many worthwhile books out there on the subject that are not only worthwhile but also give the Craft a different perspective than what American Wicca does.
Most of the following books do not have chapters on 'preachy' ethics, karma or threefold return rules. They are instead focused on witchcraft as a tradition more along the lines of an African religious system wherein the practitioner is responsible for him or herself.
Most all of these books can be obtained through Amazon but a web search should help you find them available through other sources if such is your desire. Try your local library and remember to ask your reference librarian for help in borrowing for an online “Historical Studies” class. ;) Sometimes a little BS goes a long way to cover your personal interests.
Sorgitzak: Old Forest Craft by Victoria Cummer - This is a book about the religion once practiced ages ago in the Old Forest region of Europe. The book contains channeled messages from the Gods of the Old Forest and from the fey, as well as stories, myths, legends, and bits and pieces of the old witch language. It is not meant to be a "Wicca 101" book, but the next stage towards witches, in particular those of European descent, being able to reclaim their heritage. In this regard, there is no other book currently out there quite like this one. Not only does it provide a link to the past, but it also gives witches a potential focus for the future.
Hedge-Rider: Witches and the Underworld by Eric De Vries - Hedgerider: Witches and the Underworld is a re-interpretation of (Hedge-)Witchery. Drawing from an extensive historical, folkloric and mythological body it re-attributes and re-defines Witchery as a Heathen Cult centred around the journey to the underworld and contact with the unseen. With the insights into cosmology, philosophy and practice this book provides a working body of Heathen Witch-lore, designed to transform the essence of humanity into something greater through contact with our fetch and the underworld itself primarily from a Germanic point of view. The downside to this book however is that de Vries like many of his contemporaries suffers from educated ignorance in that he doesn't actually believe in the Gods, elves or spirits he talks about in his book because he consistently refers to Them as "archetypes",the white middle-class English term people prefer to use when they're a fence rider about their spirituality. He does a great job informing you about Frau Holle, Hel and other spiritual denizens of the Otherworld yet will categorically state they're just aspects of your subconscious or in other words, 'figments of your imagination'. Other than this pathetic aspect of the book, it's pretty good.
