Depending on the counting convention used, and including all titles, charts, and edited collections, there may be currently over 500 books in Isaac Asimov's bibliography—as well as his individual short stories, individual essays, and criticism. For his 100th, 200th, and 300th books (based on his personal count), Asimov published Opus 100 (1969), Opus 200 (1979), and Opus 300 (1984), celebrating his writing.

Asimov was so prolific that his books span all major categories of the Dewey Decimal Classification except for category 100: philosophy and psychology. Although Asimov did write several essays about psychology, and forewords for the books The Humanist Way (1988) and In Pursuit of Truth (1982),Isaac Asimov, "The Way of Reason", in In Pursuit of Truth: Essays on the Philosophy of Karl Popper on the Occasion of his 80th Birthday,, ed. Paul Levinson, Humanities Press, 1982, pp. ix–x. which were classified in the 100s category, none of his own books were classified in that category.

According to UNESCO's Index Translationum database, Asimov is the world's 24th most-translated author.Index Translationum database
