“The Newberry Library, like any building from the 1800s that is full of books, is haunted. Can’t come to Chicago to experience the spirits yourself? We’ll bring the spooky to you with highlights from Newberry Digital Collections. Featured here is everything you need for Halloween, from a 17th century spell book to 20th century postcards. (The Newberry is not liable for anyone who chooses to use the spell book to summon their own ghosts, ghouls, or goblins.)”
