And they have a few calls for submissions out. From their webpage:
Tinderbox Editions will also bring an anthology of lyric essays in early 2017, along with the poet's novel Periodic Companions by Laynie Browne. We are always in the process of reading manuscripts to round out our publishing schedule.If you are interested in submitting to the lyric essay anthology, please follow the Submittalbe link at the bottom of the page. Work by Sarah Blake, Traci Brimhall, Jenny Boully, Alicia Jo Rabins, and Sarah Vap will be included, among others.
If you are interested in submitting a manuscript to Tinderbox Editions, please do so through our Submittable page. We will read prose manuscripts (personal essay, lyric essay, prose poem, hybrid) in July and August of each summer and intend to read poetry manuscripts in December and January. These open submission periods rely on donations, though for those who cannot donate, there is also a fee-free submission option as well.
