Book of Shadows

A Book of Shadows is a general name used to describe a witche's spellbook. Such items can often be found in programs of the supernatural fantasy subgenre. A Book of Shadows is a personal item, usually bound to an individual or a family and may contain any number of written spells, incantations or personal notations.

On the WB Network television series Charmed, the Halliwell sisters, aka, the "Charmed Ones" discovered their family's Book of Shadows in the attic of their family home at 1329 Prescott Street. The book was a heavy tome and had been handed down to them by the Warren line of witches. Through it, the sisters were able to not only call upon spells to unlock their inherited abilities, but they could also use it to learn about a conjunctive effect called the Power of Three.
