Alternate Worlds was first published in 1975 and became an instant classic, winning a Hugo award. This third edition brings the history of science fiction up to date, covering developments over the past forty years--a period that has seen the advent of technologies only imagined in the genre's Golden Age. As a literature of change, science fiction has become ever more meaningful, presaging dangers to humanity and, as Alvin Toffler wrote, guarding against "the premature arrival of the future." The world has begun to recognize science fiction in many different ways, incorporating its elements in products, visual media and huge conventions.

Table of contents

In its first four volumes, this much-praised historical anthology series traced how the earliest forms of fantastic fiction developed into what is now known as science fiction. Volume Six looks at sci-fi in a dozen foreign countries and offers a rich variety of stories from around the world.

This book provides students and other interested readers with a comprehensive survey of science fiction history and numerous essays addressing major science fiction topics, authors, works, and subgenres written by a distinguished scholar. This encyclopedia deals with written science fiction in all of its forms, not only novels and short stories but also mediums often ignored in other reference books, such as plays, poems, comic books, and graphic novels. Some science fiction films, television programs, and video games are also mentioned, particularly when they are relevant to written texts. Its focus is on science fiction in the English language, though due attention is given to international authors whose works have been frequently translated into English. Since science fiction became a recognized genre and greatly expanded in the 20th century, works published in the 20th and 21st centuries are most frequently discussed, though important earlier works are not neglected. The texts are designed to be helpful to numerous readers, ranging from students first encountering science fiction to experienced scholars in the field.

While students and general readers typically cannot relate to esoteric definitions of science fiction, they readily understand the genre as a literature that characteristically deals with subjects such as new inventions, space, robot and aliens. This book looks at science fiction in precisely this manner, with twenty-one chapters that each deal with a subject that is repeatedly addressed in science fiction of recent centuries. Based on a packet of original essays that the author assembled for his classes, the book could serve as a supplemental textbook in science fiction classes, but also contains material of interest to science fiction scholars and others devoted to the genre. In some cases, chapters offer thorough surveys of numerous works involving certain subjects, such as imagined vehicles, journeys beneath the Earth and undersea adventures, discovering intriguing patterns in the ways that various writers developed their ideas. When comprehensive coverage of ubiquitous topics such as robots, aliens and the planet Mars is impossible, chapters focus on major themes referencing selected texts. A conclusion discusses other science fiction subjects that were omitted for various reasons, and a bibliography lists additional resources for the study of science fiction in general and the topics of each chapter.
