This website has helped me in sooo many ways ; Basically it has books that aren't really sold around any more and most of these books are from the 1800's .
The categories are of religious texts from all kinds of traditions (A great site for pagans) Including witchcraft, Esoteric, Goetia , Homosexuality , Etc
Enjoy it and check it out
