"Scary Stories to Tell in The Dark", a children's horror book?

"Scary Stories to Tell in The Dark" is a series of three children's books written by Alvin Schwartz and illustrated by Luis Erique, Daniel Urena, and Stephen Gammell. The scary stories of the title are pieces of folklore and urban legends collected and adapted by Schwartz. The titles of the books are: "Scary Stories to Tell in the Dark" (1981), "More Scary Stories to Tell in The Dark" (1984), and "Scary Stories 3 : More Tales to Chill Your Bones" (1991). The first volume was published in 1981, and the books have subsequently been collected in both a box set and a single volume. This series is listed as being the most challenged series of books from 1990–1999 and seventh most challenged from 2000-2009 by the American Library Association for its violence. Also there remains the problem of it being classified as a children's book, due to the surreal and nightmarish illustrations contained within. (wikipedia)
