This topic got kinda stale. Just downloaded a small collection, thought I’d share the list:
“A small collection of what I personally consider to be the best introductory books on witchcraft.”
1.) Wicca : A Guide for the Solitary Practitioner
2.) Living Wicca : A Further Guide for the Solitary Practitioner
3.) Buckland’s Complete Book of Witchcraft
4.) A Witch’s Bible Compleate
5.) Sybil Leek : Diary of a Witch
6.) Drawing Down the Moon
7.) God/Goddess : Exploring the Two Sides of Wiccan Deity
8.) A Wiccan Bible
9.) The Crooked Path
10.) Maiden, Mother, Crone
11.) Circle of the Cosmic Muse
12.) Solitary Witch : Ultimate Book of Shadows for the New Generation
13.) King of the Witches : The World of Alex Sanders
Now, many of these will be on https://annas-archive.gl/
