Got his notice from poet Barbara Jane Reyes at PAWAINC (see links in the sidebar):
Attention, Northern/Central California poets: Sixteen Rivers Press, a nonprofit cooperative press based in SF, is accepting full-length poetry manuscripts now through Feb. 1, 2016. Those whose manuscripts are selected (1-2) will become members of the collective with publication in early 2018. See https://www.sixteenrivers.org/submit-work/ for details and link to submission guidelines.
Sixteen Rivers Press was founded in 1999 by seven San Francisco Bay Area writers. Our goal was to create a sustainable, shared-work publishing collective run by and for Bay Area poets. The original model was Alice James Books, which in the 1970s created a regional collective press in the Boston area.
New Members Selection:New members are selected on the basis of a book-length manuscript of poems submitted during our reading period, November 1 to February 1. Prospective members are also asked to identify their interest in collective publishing and the skills they can bring to the press’s operation.
