Read the excerpt from "How the Grimm Brothers Saved the Fairy Tale."

Between 1812 and 1857, seven editions of their tales appeared, each one different from the last, until the final, best-known version barely resembled the first. Given that the first edition has recently been honored in bicentenary celebrations throughout the world, it is perhaps a good time to reexamine what we think we know about the original tales of the Brothers Grimm.
