This book was inspired by the film "Nosferatu" (1922). "The Book of the Vampires" was a small book prop used in the movie. This is the english version (the movie is German).
Nosferatu book can be seen @ 13:45
The Book of the Vampires
"horrible darkness, on the cursed earth from the graveyards of the Black Death."
"Wherefore there is no salvation therefrom except that a woman pure in heart were to make the vampire forget the cock’s first crowing. Of her own free will would she have to give her own blood."
For the record, I'm not "into" vampires. I do like the 1922 version of "Nosferatu".
