Hardcover. 273pp. Illustrations, bibliography, index.
An overview of the literature and the myriad of theories and oddities that have been put forward over the past century. Thorough the well-written, though not all-inclusive. Numerous works of non-fiction - both old and new - are not discussed at all. Nevertheless, a fascinating overview of the study, where we've been and where we're going. Recommended.
