We’re talking about complete scans of 1,600+ rare occult texts from the late 15th Century onwards. It’s pretty incredible, actually, that people can just access this once-obscure material from any Internet connection around the world. Talk about your modern-day Library of Alexandria.
I’ve bookmarked a bunch of these texts to dive into when I have the time, and I’ve included links to them below. Since I admittedly mostly read English (though I am learning a fair bit of Portuguese), these will be in that language.
