Charles N. Brown, Ed Meskys, and Dave Vanderwerf founded Locus in 1968 as a news fanzine to promote the (ultimately successful) bid to host the 1971 World Science Fiction Convention in Boston, Massachusetts.
Originally intended to run only until the site-selection vote was taken at St. Louiscon, the 1969 Worldcon in St. Louis, Missouri, Brown decided to continue publishing Locus as a mimeographed general science fiction and fantasy newszine.
[1][3] Locus announced that the magazine would continue operations, with then executive editor Liza Groen Trombi succeeding Brown as editor-in-chief in 2009.
"[14] It was later clarified by Locus that the edits were not intended to be made to work already published, but rather going forward, to future reviews.
[16] Developed initially as a reading list for the Hugo Awards,[17] they have since come to be considered a prestigious prize in science fiction, fantasy and horror literature.
It is often more up-to-date than the awards' own websites (according to The Encyclopedia of Science Fiction),[3] and has received praise from editors and authors of SF.
