Traditionally, the Book of Shadows is a spell book used by witches. It is usually a magickal and religious text.

However, as times change and witchcraft evolves, it has become more of a personal journal used by witches to hold thoughts, dreams, and useful spells. The Book of Shadows in contemporary terms is not a tome you can purchase in a store and study. It is generally a collection of spells.
