I do really enjoy folk-tales, and this book included a few elements that I hadn't considered from a tradition/etymological perspective: the weirdness around dwarves being smiths but also repelled by iron, the irrationality of what fairies do with the human babies they swap changelings for, and the moral (or lack thereof) of the stories around not letting a fairy spouse have access to (usually her) home are all rather perplexing. I did enjoy the leprechaun dialect stories, though, and Ashliman's explanations of some of the types of fairy stories and their articulation through the ages was lucid.
