Book of Shadows
The Japanese horror adventure game "Corpse Party: Book of Shadows" deals with the eponymous book during its final chapter, in which it is revealed to be an actual Book of Shadows very much in keeping with the description in this article (albeit in the game, there is only one Book of Shadows that exists, containing a complete chronicle of all spells that exist in the entire world, be they Wiccan or not). The Book of Shadows returns in "Corpse Party: Blood Drive" where it becomes a key element to the story throughout the game.
