The World Fantasy Awards are given each year by the World Fantasy Convention for the best fantasy fiction published in English during the previous calendar year. The awards have been described by book critics such as The Guardian as a "prestigious fantasy prize", and one of the three most prestigious speculative fiction awards, along with the Hugo and Nebula Awards. The World Fantasy Award—Novella is given each year for fantasy stories published in English. A work of fiction is eligible for the category if it is between 10,000 and 40,000 words in length; awards are also given out for longer pieces in the Novel category and shorter lengths in the Short Fiction category. The Novella category has been awarded annually since 1982, though between 1975—when the World Fantasy Awards were instated—and 1982 the short fiction category covered works of up to 40,000 words. In 2016, the name of the category was changed from Best Novella to Long Fiction, before reverting to Novella in 2018.
