I co-run Sad Press Poetry with Sam Walton. We mostly publish first collections. We're publishing poetry by SFF writers Adam Roberts and Roz Kaveney soon.
I also have about ten pamphlets and books out, mostly written with others. See for instance: We Are Real, Sea Adventures, or, Pond Life, Pressure in Cheshire, Hax, Animal Poems. If you'd like to read something and have trouble getting it, let me know and maybe I can help.
