Reactor regularly publishes shortfiction on its website. While not a true webzine, it is indexed as it is a SFWA recognized market that publishes many significant genre authors. The webzine format is used as it is the closest format we have for the blog nature of the Reactor site. Only the shortfiction posts (along with the accompanying illustration) should be indexed. The story's editor is typically used as the webzine editor. Tor.com rebranded to Reactor on January 23, 2024.
