In this case- The Witches Spellbook is the Grimoire of Winifred Sanderson. In many cases, the books themselves are believed to be imbued with magical powers, although in many cultures, other sacred texts that are not grimoires (such as the Bible) have been believed to have supernatural properties intrinsically. The only contents found in a grimoire would be information on spells, rituals, the preparation of magical tools, and lists of ingredients and their magical correspondence.[unreliable source?] In this manner, while all books on magic could be thought of as grimoires, not all magical books should be thought of as grimoires.
