Magick in Theory and Practice
Aleister Crowley
Dover
1976 Reprint of 1929 Edition. Many consider this work by Crowley to be the foremost book on ceremonial magic written in the twentieth century. It was written especially for beginners as Part 3 of Book 4 (Liber ABA). The original was privately printed in 1929 after Crowley failed to find a publisher in London.
