Scary Stories to Tell in the Dark is a series of three collections of short horror stories for children, written by Alvin Schwartz and originally illustrated by Stephen Gammell. In 2011, HarperCollins published editions featuring new art by Brett Helquist, causing mass controversy amongst fans of Gammell. Subsequent printings have restored the original Gammell art. 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 three books each feature numerous short stories in the horror genre. Author Schwartz drew heavily from folklore and urban legends as the topic of his stories, researching extensively and spending more than a year on writing each book. Acknowledged influences include William Shakespeare, T. S. Eliot, Mark Twain, Joel Chandler Harris, Bennett Cerf and Jan Harold Brunvand. The first volume was published in 1981, and the books have subsequently been collected in both a box set and a single volume. There is also an audiobook version of each book, read by George S. Irving. The audiobooks are presented in unabridged format with the exception of a handful of missing stories from the first book. As of 2017, the books had collectively sold more than seven million copies, and appeared on numerous children's best-seller lists. They have collectively been hailed as a "cultural touchstone for a generation", with the original charcoal and ink artwork by Gammell often singled out for praise. A film adaptation of the same name was released on August 23, 2019 to generally favorable reviews from critics. Books Editions To celebrate the books' 30th anniversary in 2011, HarperCollins re-released the books with new illustrations from Brett Helquist. The new illustrations were generally regarded as kid-friendly and not as disturbing as their previous illustrations, resulting in widespread criticism from fans of the original. In 2017, the books were re-issued with the original artwork. Reception Controversy This series is listed by the American Library Association as being the most challenged series of books from the 1990s, and seventh most challenged from the 2000s. It again made the list in 2012. Complaints have typically centered on its violence, disturbing subject matter, and potential unsuitability for younger readers, as well as religious concerns. Critics have called the stories, many of which feature macabre topics such as murder, disfigurement and cannibalism, "sick... repulsive",
