What a delightful resource! This encyclopedic reference book offers a wealth of information on all kinds of fairies and fantastic creatures (brownies, djinn, demons, nymphs, dwarves, etc.) from a wide range of cultures: not just European, but also Asian, African, Middle Eastern, and various Native American tribes. It also contains bios on some of the great researchers and contributors to fairy-tale literature.
Keep in mind that the Element Encyclopedia of Fairies is a "launch pad" of sorts. Some entries are lengthy and include famous stories about the creature at hand. Others are shorter, limited to descriptions of the creature's appearance, history, or behavior / mannerisms. That was fine with me; there's only so much you can cover in 570-ish pages. This book provides the foundation for later, more extensive research I can do on other creatures in the future. The only reason it took me so long to read it? It wasn't as high of a "priority" to finish it as my reading-for-fun books. ;)
