Science Fiction literature, also known as sci fi and sf, is one of the more recent genres, and also one of the more popular. It only truly emerged during the 20th century, and has not stopped growing in terms of authors, titles and readers. It has also evolved into a variety of subgenres, ranging from hard sf to soft sf, from Utopias to dystopias, with more than a smattering of horror, detective, war and feminist titles.

Stableford covers all these aspects and more, taking a close look at what has become a booming industry, with its specialized writers, publishers, and fan magazines. The compendium includes not only sf from the United States and United Kingdom, but also France, Russia, and many others. While the chronology charts the genre's dazzling growth, and the dictionary section looks at writers, books, themes, and other specifics, the introduction provides exceptional insight into what Science Fiction Literature is all about.
