I bought this General Books "reprint" of Crowley's 1913 book because it seemed cheap. It turns out to have been automatically scanned and rewritten by Optical Character Recognition software. It therefore has no pictures, numerous typos and missing text. Crowley's terse and allusive original text demands accurate reproduction and this edition is wildly infuriating. In recognition of this major defect, the publishers offer access to an online pdf of the original. I wouldn't have bought the book if I wanted to read it on screen. I have ordered a proper copy elsewhere. Apparently cheap, but very poor value for money.
