This collection of 100 brief (2-3 page) essays by British sf magazine editor Pringle offers an informed and admittedly subjective guided tour of a genre that encompasses such widely divergent titles as Tolkien's Lord of the Rings (1954-55), Flann O'Brien's The Third Policeman (1967), and Stephen King's Salem's Lot (1975). Following the format of his earlier collection, Science The 100 Best Novels (LJ 7/86), Pringle presents his selections in chronological order and includes a synopsis of the story, a discussion of the author's overall contribution to fantasy literature, critical commentary on the title's significance, and a brief publishing history. An introductory essay tackles the difficulty of defining fantasy, while a "Brief Bibliography" directs readers to other discussions of the genre. By no means a definitive subject guide, this entertaining volume should serve as a solid introduction to the elusive field of imaginative literature. Recommended for most libraries.
