One of the most prolific writers of all time, Isaac Asimov wrote or edited more than 500 books during his career. In addition to his trailblazing work in science fiction, Asimov has been published in nine of the ten major categories of the Dewey Decimal System, a testament to his breadth of knowledge and interests. Asimov's life's work was to educate and pique the reader's curiosity with science, and to prompt thought about how our current actions have an impact on what the future will bring.
