Arthurian Encyclopedia (Garland Reference Library of the Humanities)

This is probably one of the single most authorative Arthurian sourcebooks I have ever seen, giving detailed information on thousands of ballads, epics, manuscripts, fairy tales, poems, novels, plays, and movies concerning Arthur and his knights, in virtually every language and culture conceivable from Hebrew to Welsh to Tagalog. There is also a smattering of black-and-white drawings throughout, and some entries pretaining to the historical basis of the Arthurian Cycles, all of which are accurate and informative.
