The Nebula Award for Best Novel is given each year by the Science Fiction and Fantasy Writers of America (SFWA) for science fiction or fantasy novels. A work of fiction is considered a novel by the organization if it is 40,000 words or longer; awards are also given out for pieces of shorter lengths, in the categories of short story, novelette, and novella. To be eligible for Nebula Award consideration, a novel must have been published in English in the United States. Works published in English elsewhere in the world are also eligible, provided they are released on either a website or in an electronic edition. The Award has been given annually since 1966. Novels which were expanded forms of previously published stories are eligible, and novellas published individually can be considered as novels if the author requests it. 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.
