Fairies are a challenging subject, intertwining culture, folklore, and anecdotal accounts across centuries and millennia. Focusing primarily on the Celtic speaking cultures, with some material from adjacent cultures including Anglo-Saxon and Norse, A New Dictionary of Fairies has in-depth entries on a variety of fairies as well as subjects related to them, such as why we picture elves with pointed ears or where the idea of fairies being invisible comes from. It also tackles more complicated topics like the nature and physicality of the fairy people. Anyone with an interest in the Good Neighbours will find this book a solid resource to draw from.
