Harvard's George C. Simpson called the late Isaac Asimov "one of our natural wonders and national resources," for his hundreds of nonfiction works on science, mathematics, history, and literature. Asimov, however, is best known as a science fiction writer. This second edition, Isaac Asimov: The Foundations of Science Fiction, updates and expands science fiction scholar James Gunn's definitive, Hugo Award-winning critical volume about Asimov and his contributions to the science fiction genre. A concluding chapter analyzes Asimov's best-sellers. Those interested in Asimov and science fiction will want Gunn's study, with its insider's look at the most prolific author of the twentieth century, its chronology, selected list of critical works, and bibliography. Paperback version available 2005.
