Reflecting on L. Frank Baum's entire series of full-length Oz books, this study introduces readers to the great folklorist who created not only Dorothy and friends, but countless wonderful characters who still await discovery. Close analysis of each book invites readers to search Baum's fascinating stories for meaning and mythical quality. Progressing chronologically through the canon, the author discusses literary devices and important thematic implications in each book, arguing that Baum wrote for the pleasure of both children and adults, both to provide entertainment and to teach moral lessons. Of particular significance is the argument, sustained over several chapters, that Baum modeled his Oz books on classic mythical patterns, rewriting Oz history in nearly every book to produce a different set of backgrounds and a different conception of utopia for his imaginary kingdom. Examinations of his non-Oz books and his other Oz works illuminate the discussion of the Oz novels.
