This is the 1989 first edition hardcover which still retains material removed from later editions, including De Arte Magica Liber CDXIV (Book 414). This book was edited by Scott Michaelsen and has forewords by Robert Anton Wilson and Genesis P-Orridge.
This is Liber CDXIV (Book 414) and was originally written by Crowley between Sep 6 and Oct 8, 1914. Although this document was released and widely disseminated by Ordo Templi Orientis under the same limited license as the other text files, it is now considered by the Order to be under seal of a particular degree. One particular chapter of this book, “Of Eroto-comatose Lucidity”, is still widely available as Liber CDLI (Book 451). Another special edition of this text is still available from J D Holmes, as of the time of this post, from a limited run of 9 hand-numbered copies, published in 2001.
