The following document is supposedly The Vampire Bible as published by the Temple of the Vampire (http://www.vampiretemple.com/) for $20-$40, shipping included ;-). It was banned from Google Internet and Google Usenet group searches by a request to the DMCA (http://www.chillingeffects.org/dmca512/notice.cgi?NoticeID=574). You can check the date and author from there, to ascertain that it is in fact the same document posted to the Usenet in 1996.
Disclaimer: If you do not own this book then you must delete it within 24 hours of reading the whole copy. Oh, and do support the Temple of the Vampire, I’m sure they can use every cent ;-)
Now served in all it’s glory, in fresh PDF format for your viewing pleasure:
