"Each of the Folklore of the World Books contains carefully selected myths and folktales most representative of a single country. These books will help children to understand people in other lands and will help them to develop an appreciation for their customs and culture. Peace for the world can come only through the spreading of this understanding and appreciation....In all the series, emphasis is placed on good storytelling and literary quality, as well as on simplicity of vocabulary."
