The J. Lloyd Eaton Conferences on Science Fiction and Fantasy Literature--long held at the University of California, Riverside--have been a major influence in the study of science fiction and fantasy for thirty years. The conferences have attracted leading scholars whose papers are published in Eaton volumes found in university libraries throughout the world. This collection brings together 22 of the best papers--most with new afterwords by the authors--presented in chronological order to show how science fiction and fantasy criticism has evolved since 1979.
