markets
Pro- and Pro/Am-markets for speculative literature. Only places where you can be published with speculative literature -- not for markets (like Locus) that are about SF.
Interzone
Interzone is a major British SF (and Fantasy) magazine. SFWA no longer classifies it as a qualifying market; nonetheless it has an impressive backlist that includes Brian Aldiss, Charlie Stross, Greg Egan, William Gibson, and a host of others.
Interzone was acquired by TTA Press in 2004, and is subject to ongoing re-tuning. The TTA website doesn't give a lot of history; Wikipedia does slightly better.
