Globalization and science fiction are reflected—and refracted—in the globalization of science fiction. Much of my work on early Latin American sf has examined the great degree to which science fiction is and has long been a global genre, read and written around the world, forming a planet-spanning continuity—or, to use Damien Broderick’s terminology, a “megatext web” made up of “collective intertextualit[ies]” (“Megatext,” The Encyclopedia of Science Fiction. Online. 18 Aug. 2012). Yet I am constantly tripping over ways in which sf is not global or at least not so global as I had unconsciously slipped into assuming it was.
