As you've most likely already read, the Satanic Bible is the core book in Satanic Philosophy and method, so make sure you read and re-read it. In it, you will be either shocked by the savagery of LaVey's writings, or be held in awe by his brilliance and logic. Satanists find reflection and illumination within this Diabolical book, for it is within its pages that one realises their full potential. "Satanists are born, not made" is indeed true and one will find that terminology defined in the Satanic Bible.
I broadly see Satanic Literature defined by two categories; Philosophy/Logic and Dogma/Ritual. The Satanic Bible has both of these, however there are many other books by Church of Satan
members that expand upon these concepts. It is widely suggested that when one finishes the Satanic Bible, they purchase The Satanic Scriptures by Peter H. Gilmore, the current High Priest. His book provides a "bridging" so to speak over the 40 years of Satanism.
Good luck with your readings, and enjoy your stay.
