The
Nebula Awards are given each year by the
Science Fiction and Fantasy Writers of America (SFWA) for the best
science fiction or
fantasy fiction published in the United States during the previous year. The award has been described as one of "the most important of the American science fiction awards" and "the science-fiction and fantasy equivalent" of the
Emmy Awards. The
Nebula Award for Best Novel is given each year for science fiction or fantasy
novels published in English or translated into English and released in the United States or on the internet during the previous calendar year. A work of fiction is defined by the organization as a novel if it is 40,000 words or longer; awards are also given out for pieces of shorter lengths in the
short story,
novelette, and
novella categories. The Nebula Award for Best Novel has been awarded annually since 1966. Novels which were expanded forms of previously published short stories are eligible, as are novellas published by themselves if the author requests them to be considered as a novel.
