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 (which cover both fantasy and science fiction). The World Fantasy Award—Novel is given each year for fantasy novels published in English or translated into English. 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 Fiction and Novella categories. The Novel category has been awarded annually since 1975.
