Compares what writers over the centuries have written about an imaginary future with the reality revealed by time.

The first science fiction course in the American academy was held in the early 1950s. In the sixty years since, science fiction has become a recognized and established literary genre with a significant and growing body of scholarship. The Cambridge History of Science Fiction is a landmark volume as the first authoritative history of the genre. Over forty contributors with diverse and complementary specialties present a history of science fiction across national and genre boundaries, and trace its intellectual and creative roots in the philosophical and fantastic narratives of the ancient past. Science fiction as a literary genre is the central focus of the volume, but fundamental to its story is its non-literary cultural manifestations and influence. Coverage thus includes transmedia manifestations as an integral part of the genre's history, including not only short stories and novels, but also film, art, architecture, music, comics, and interactive media.
