These are a series of book lists, by topic, that I recommend when asked about Pagan books. When there is a great deal of overlap, the book is listed in more than one location. This list is eclectic in nature, for the modern (revival and inspiration-derived Pagan), rather than geared for someone interested in reconstructionism or a purely devotional polytheistic point of view.
This list is a work in progress, particularly in terms of links, which connect to Amazon, though some books may be available in the public domain for free. It is geared towards forming a widely-read awareness of the diversity of Pagan paths…and there are plenty of good books that I haven’t added yet! Also, the categorization/best use of the books is purely my opinion…
Books with a * are personal favorites.
Introductory Books:
This is the list that I recommend for anyone interested in Paganism. I recommend these books for a combination of reasons–some because they are a well written basic introductory overview or because they are widely read among Pagans, others because they are well researched histories or historically important (or some combination thereof). At the very least, this list will ensure an introduction to most of the main traditions, the overall history, and prevalent themes within contemporary Paganism.
