No, this section isn't required reading for a class at Hogwarts, and it has nothing to do with Harry Potter. But it does contain books about Shadow Magic, demonology, and the darker side of the occult. Among the books in this section, you will find tomes related to the Necronomicon, also known as The Book of the Dead, a grimoire created by fiction author H.P. Lovecraft and featured in his stories. According to Lovecraft, the Greek version of the Necronomicon has not been seen "since the burning of a certain Salem man's library in 1692" (the year of the Salem Witch Trials). Don't be afraid of the dark: knowledge is power!
