might have come from Crowley's Journal called The Equinox: Book of Thoth -A Short Essay on the Tarot of the Egyptians, Equinox Volume III, No.V. (I understand there were 10 issues) Then he expanded that and self published in 1944 The Book of Thoth to go with the Cards painted by Freida Harris.
Not quite. The Book of Thoth
actually is the Equinox vol III, no.V.
Volume I, no.1 - 10: The Review of Scientific Illuminism was classed as a journal because of it's bi-annual publication. This is despite the fact that each number was hardback and over 200 pages each! (Sometimes 400+ pages.)
Volume 2 is classed as a volume of silence for obvious reasons.
Volume 3, No.1 was Crowley's attempt to restart the Equinox series. But due to various financial problems and hysterical persecution of OTO members in Detroit, No.2 was never published and only survives as galley proofs.
After this the Equinox was continued in a rather sporadic fashion. Some of Crowley's later books were released under the imprint of the Equinox, even though they have little in common with the original Equinox, which was a mixture of magical instruction, plays, short stories, book reviews etc., etc. The editions after Vol III, No.2 are all books in their own right. No.3 The Equinox of the Gods, No.4 Eight Lectures on Yoga, No.5 The Book of Thoth, No.6 Liber Aleph, No.7 Shih Yi (I Ching), No.8 The Tao Teh King, No.9 The Holy Books of Thelema. Some of these weren't even published in Crowley's life time.
