The World Fantasy Awards are given each year by the World Fantasy Convention for the best fantasy fiction and fantasy art published in English during the preceding calendar year. The awards have been described by sources such as The Guardian as a "prestigious fantasy prize", and as one of the three most renowned speculative fiction awards, along with the Hugo and Nebula Awards (which cover both fantasy and science fiction). The World Fantasy Award for Life Achievement is given each year to individuals for their overall career in fields related to fantasy. These have included, for example, authors, editors, and publishers. The specific nomination reasons are not given, and nominees are not required to have retired, though they can only win once. The World Fantasy Award for Life Achievement has been awarded annually since 1975.
