I recently had a couple of prose poems accepted for a new anthology forthcoming in 2011 published by Equinox Publishing. This is called,
CLASSIFIEDS: AN ANTHOLOGY OF PROSE POEMS
[ISBN 978-0-9845659-1-7; $19.95; PUBLICATION DATE: 2011]
They are STILL looking for submissions so this is your chance to find yourself in an anthology! Submit now. They are accepting until the end of December. While they appear to be looking for a particular type of prose poem--see the link in the title of this post--I think they are fairly open to whatever you produce...
Give it a shot. What's the worst that can happen?
