"The BSFA Awards are presented annually by the British Science Fiction Association, based on a vote of BSFA members and – in recent years – members of the British national science fiction convention Eastercon. They are fan awards that not only seek to honour the most worthy examples in each category, but also to promote the genre of science fiction, and get people reading, talking about, and enjoying all that contemporary science fiction has to offer."
There were a few years without an award for a novel, and one year with two winners.
