Among his best-known science-fiction works are I, Robot (1950); The Foundation Trilogy (1951-1953), to which he wrote a sequel 30 years later, Foundation's Edge (1982); The Naked Sun (1957); The Gods Themselves (1972). Among his major science books are the Biographical Encyclopedia of Science and Technology (1964; revised 1982) and Asimov's New Guide to Science (1984), a recent revision of his widely acclaimed Intelligent Man's Guide to Science (1960).
