As for the works of Crowley you are asking for, I am trying to read them when I can in the order he wrote them as much possible to try (difficult as it sometimes is) to follow the development of his thought. This goes without saying it requires certain knowledge of Occult concepts outside of his own writing (Qabalah, Tarot, Ceremonial Magic, etc.).
Of course, I started with THE LAW IS FOR ALL
I have perused but passed on his GOETIA work at this point in my studies and will come back to it in the future.
Then I went in this order:
KONX OM PAX
777
AHA!
THE UNIVERSE
TAROT DIVINATION
THE BOOK OF LIES
BOOK 4
LIBER ALEPH vel CXI
I have been reading MAGIC WITHOUT TEARS and MAGICK IN THEORY AND PRACTICE out of order. I'm not quite sure why the method but they seem to blend into all of his writings.
On another note, I've also read DIARY OF A DRUG FIEND and MOONCHILD for a welcome break.
Of course my list is missing several titles. But these are the only physical books I have. (I am not counting my numerous PDFs and Xeroxes. You just can't beat the actual books!)
Hope this helps.
