NightBallet Press is seeking submissions for its new anthology, Buzzkill: Apocalypse. The editor wants one or two poems that explore the theme of "the End." Previously published poems are welcome, and some of the already-selected contributors include John Burroughs, Lyn Lifshin, and Michael Salinger. The submission deadline is May 1st. (Thanks to J.E. Stanley for mentioning this one.)
Speaking of deadlines, Midnight Echo, the magazine of the Australian Horror Writers Association, closes to submissions January 31st. And Electric Spec ends their current reading period on January 15th (though they'll still be open to submissions).
