The Future as Nightmare
Hillegas, Mark R. The Future as Nightmare: H.G. Wells and the Anti-utopians. New York City: Oxford UP, 1967. Carbondale, IL: Southern Illinois UP, Arcturus, 1974.
Occasionally inaccuate but still indispensable. Deals with Wells's utopian and anti-utopian works and their influence on Y. Zamiatin, A. Huxley, G. Orwell, and others; quite good on E. M. Forster's "The Machine Stops" (all listed under Fiction).
