Interesting, lovely unpublished work (unpublished as a whole; individual pieces may be published already of course), prose or poetry or some combination or something between genres, 18-44 manuscript pages (no more than one poem per page if you're sending poems unless they are very, very short).

We recommend that your manuscript be as coherent--as much a project--as possible. Not to say everything needs to be thematic or narratively related, but most of our winning chapbooks have a feeling of aesthetic unity or resonance:books should make sense as books. Chapbook manuscripts do not necessarily have to be diagrammatic (though the diagrammers among us do enjoy those).
