The BSFA Awards are given every year by the British Science Fiction Association. The Best Long Non-Fiction award is open to any written work about science fiction or fantasy which appeared in its current form in the previous year. Whole collections of work that has been published elsewhere previously are ineligible as is work published by the BSFA. The award was previously named the BSFA Award for Best Non-Fiction; it was renamed to Best Long Non-Fiction in 2023.
