Here are a few sites, blogs, and other places of interest I've found.
The Hermetic Library - An indispensable resource on Thelema (and other works by Aleister Crowley), with some material by and pertaining to other occultists such as Frater Achad and W. B. Yeats; also, some material on Enochian, Golden Dawn, and various grimoire systems of Magic. I also like their archives of numerous esoteric periodicals, including The Equinox and Caduceus.
Thelemic Order of the Golden Dawn - A site that has a full curriculum of self-initiation. Haven't studied it in-depth, but it's certainly worth a look for those who might be interested.
