The Alvin Schwartz Series:

Scary Stories To Tell in the Dark
This is the first book in the Alvin Schwartz series which is a mixture of ghastly folktales modified with a certain creepyness. The stories within it are intended for a younger audience but they are definitly fun to read for a wider variety of generations. My favorite story in this book is Me-Ty-Doughty Walker. It's about a boy who stays in a haunted house overnight upon a bet and is greeted with a bloody head that falls down the chimney.

More Scary Stories to Tell in the Dark
This is the next book in the series and is just as creepy as the first book. One of the stories you may be familiar with. It's called Wonderful Sausage. It's about a butcher who turns his customers into sausage meat but eventually falls into his own trap...

Scary Stories 3 : More Tales to Chill Your Bones
This is sadly the last book in the collection. Each of these books are not only terrifying but they have excellent illustrations that set the mood of each tale. This third book is just as good as the first two. There's a story called Harold in it that's about two farmhands that make a dummy of a farmer that they hate. The more they abuse the doll it comes to life and eventually gets them.

Stephen King:
