Just apocryphal texts and gnostic texts. The theosophical society will likely have a lot of these texts as well as online places. Keep in mind the theosophical society is extremely right hand oath and their libraries likely only contain what they agree with. +

There are some gnostic texts that view Lucifer positively or the abrahamic deity negatively so those likely won't be included. Went to a library of theirs one time. The grounds were VERY abrahamic energy wise but the library was very draconic energy wise. Idk if you'll have any physical locations

What does being “extremely right hand oath” mean?
