I edit the Quareia course, a full magical training available completely free of charge online. To give you an idea of the course’s magnitude, when Josephine McCarthy hit the halfway mark writing the course, her full manuscript stood at roughly 1,500 pages of single-spaced A4, equal in length to about eight novels.
Josephine writes the Quareia course, has taught and written on occult and Western Mystery themes in the USA and UK for the last two decades, and has been involved in magic and the occult for thirty-five years. In addition to the Quareia course she has written many other books on magic, keeps an online blog, and maintains another site, The Inner Library, which houses work by her and her partner Stuart not tied in to the Quareia curriculum.
Goblyn Market sells the original artwork and commissions of artist Stuart Littlejohn, and signed books by Josephine McCarthy, as well as magical oddities and curiosities.
Frater Acher’s website, available in German and English. Having now tried and failed for the last twenty minutes to write a halfway-adequate description of his site, and come up with only “it contains a huge number of incredibly useful things,” I think it’s probably best if you just visit his site yourself to find out what it’s about.
If you live near London, are of an Egyptological persuasion, and have a hankering for research, then it is well worth the thirty quid joining fee. You get access to all back issues of the Journal of Egyptian Archaeology on JSTOR, as well as the excellent Ricardo A Caminos Memorial Library in London.
The wonderful Oriental Institute of Chicago has made a great deal of their publications freely available online, a godsend to the impoverished researcher. A great many treasures here.
JSesh is an open source editor for ancient Egyptian hieroglyphic texts. It’s currently quite powerful, and it covers most of the so-called Manuel de Codage. This program was a lifesaver for editing the Egyptian module of the Quareia course—the alternative would have been me handwriting out every god-name and title and scanning them in, which would not have looked half so good. It is now proving invaluable for my book on Egyptian magic.
