SF

SF as used on this site is, like feminism, a big tent: Here it means any fiction that is not, at the time it was written, "realistic". "SF" therefore includes "science fiction", "speculative fiction", "alternative history", "utopian fiction", "surrealism", "fantasy", "magical realism", "supernatural fiction", "myth", "folklore", "horror", "weird fiction", and certainly "scientifiction". Ellen Datlow has described some apparently realistic fiction as having "speculative sensibilities". SF, properly viewed, can encompass fiction that blurs the lines, such as folk tales and parables, which sometimes have supernatural or nonrealistic elements, and other times not; or gothic romance, which similarly sometimes have supernatural elements, or suggestions of supernatural elements.

Any and all media are open game: literature, art, graphic novels, films/TV, even music.
