Hugo Award for Best Series
The Hugo Awards are given every year by the World Science Fiction Society for the best science fiction or fantasy works and achievements of the previous year. The award is named after Hugo Gernsback, the founder of the pioneering science fiction magazine "Amazing Stories", and was once officially known as the Science Fiction Achievement Award. It has been described as "a fine showcase for speculative fiction" and "the best known literary award for science fiction writing". The Hugo Award for Best Series is given each year for series of science fiction or fantasy stories published consisting of at least 3 works totaling at least 240,000 words, with at least one work released or translated into English during the previous calendar year. The Hugo Award for Best Series has been awarded annually since 2017. It was started then as a one-time special Hugo Award in advance of a vote to make it a permanent category, and was ratified as such by members of the World Science Fiction Society that year.
Hugo Award
The official logo of the Hugo Awards is often placed on the winning books' cover as a promotional tool. Gahan Wilson, in "First World Fantasy Awards" (1977), claimed that noting that a book had won the Hugo Award on the cover "demonstrably" increased sales for that novel, though Orson Scott Card said in his 1990 book "How to Write Science Fiction & Fantasy" that the award had a larger effect on foreign sales than in the United States. Spider Robinson, in 1992, claimed that publishers were very interested in authors that won a Hugo Award, more so than for other awards such as the Nebula Award. Literary agent Richard Curtis said in his 1996 "Mastering the Business of Writing" that having the term Hugo Award on the cover, even as a nominee, was a "powerful inducement" to science fiction fans to buy a novel, while Jo Walton claimed in 2011 that the Hugo is the only science fiction award "that actually affects sales of a book".
