Here is one of the most amazing books I have found in a used book store to date.
The Mystical & Magical System of the A∴A∴
The Spiritual System of Aleister Crowley & Cecil Jones Step-by-Step.
By James A. Eshelman
After flipping through this book today it appears to contain almost everything you could possibly want to know about the A∴A∴ It is a step by step guide.
It starts at the student level and goes from probationer to neophyte all the way up to the dominus liminus grade.
Here are some pictures of it, Hardcover with a dust jacket.
