"The O.T.O. has the rights to Crowley's writings and since *Magical & Philosophical Commentaries * was not done with the permission of the O.T.O. I don't expect there is going to be a reprint."
Since Magical and Philosophical Commentaries was published in 1974, and O.T.O. did not purchase the Crowley copyrights until the early 1990s, Grant and Symonds did not need their permission. Obviously the situation is different now, and I agree that it's unlikely there will be a republication.
I wouldn't discourage anyone from buying this book in anticipation of a fuller publication from Bill Breeze, for two reasons. The first is that the two publications will be very different; Bill's will doubtless have much more in the way of material perhaps edited out by Grant and Symonds, or perhaps simply not to hand in the early 1970s, and there will be copious notes and cross-references, but regardless of merit any notes by Grant will not be included (I appreciate that some will not regard this as a loss). The second reason is that there is a bottleneck in what is currently being prepared for publication, and it may be a while before this and other projected publications materialise.
Best wishes,
Michael.
