Asimov's career can be divided into several periods. His early career, dominated by science fiction, began with short stories in 1939 and novels in 1950. This lasted until about 1958, all but ending after publication of "The Naked Sun" (1957). He began publishing nonfiction in 1952, co-authoring a college-level textbook called "Biochemistry and Human Metabolism". Following the brief orbit of the first man-made satellite Sputnik I by the USSR in 1957, his production of nonfiction, particularly popular science books, greatly increased, with a consequent drop in his science fiction output. Over the next quarter century, he wrote only four science fiction novels. Starting in 1982, the second half of his science fiction career began with the publication of "Foundation's Edge". From then until his death, Asimov published several more sequels and prequels to his existing novels, tying them together in a way he had not originally anticipated, making a unified series. There are, however, many inconsistencies in this unification, especially in his earlier stories.
