I recently stumbled across a huge thread (http://boards.4chan.org/t/thread/790811) with hundreds of gigabytes of occult-related documents, etc.
Hopefully you can all get some use out of it. I've found it quite helpful as I've been trying to graft different spells together.
Eris willing, maybe some of them can end up in the file repository (https://chaos.seisat.su/files/text/) so that an even broader range of practitioners may access them.
