Totally agree with this. I think you need to move on from “Wicca 101”-type of books. Here are a few recommendations:
Historical Books
Drawing Down the Moon by Margot Adler. It’s mostly a historical account but really useful for reference, I made a video summary here.
Triumph of the Moon by Ronald Hutton. Also mostly historical, with a very academic view.
Alex Sanders Lectures. Educational history of traditional Wicca.
Worship
The Witches’ God by Janet and Stewart Farrar. A comprehensive dictionary of over 1000 gods from many world cultures, past and present.
Rites of Worship: A Neopagan Approach by Isaac Bonewits. A guide with ceremonies and rituals for public and private services.
Deepening Witchcraft: Advancing Skills & Knowledge by Grey Cat. Mostly intermediate material for people advacing past the 101 stuff.
The Elements of Ritual by Deborah Lipp. With deep focus on the Wiccan ritual, it goes to the core of practice and correspondences.
Grimoires
Mastering Witchcraft: A Practical Guide for Witches, Warlocks & Covens by Paul Huson. Interesting non-Wiccan perspective on Witchcraft.
The Grimoire of Lady Sheba by Lady Sheba
First published in 1974, this is a personal magickal workbook copied by hand from the time of her initiation into the Craft.
A Grimoire of Shadows: Witchcraft, Paganism, & Magick by Ed Fitch. The sourcebook from which a large number of Wiccan traditions have developed.
