Black Gate – Online magazine with a focus on fantasy literature. Notable for in-depth reviews and analysis of both current novels and genre classics.
Kaleidotrope – Quarterly online magazine of fantasy/SF stories and poetry. It has a distinct leaning towards the strange and the quirky, and if that is your sort of thing, you’ll enjoy this.
Strange Horizons – Weekly magazine of stories, articles, poetry and reviews – leaning heavily towards in-depth articles and interestingly experimental fiction. SF’s supposed to be the literature of ideas, and this zine tries very hard to prove it.
