2007 was the 50th anniversary of the publication of King Arthur's Avalon, which sold 100,000 copies, and is credited widely with a major share in the growth of Glastonbury's fame and the international renewal of Arthurian interests. This edition gives the original text, unchanged and unabridged, with a new Preface by the author putting it in a present-day perspective. He reviews developments in the past half-century and his own contributions to them.
