During my fieldwork, I recorded, transcribed and translated a dozen or so narratives in an indigenous language of Central America, in close cooperation with a couple native speakers (including some beautiful illustrations). Now we'd like to publish these narratives in an open source book --- but not necessarily (or at least not only) as a linguistics textbook.
I think lang-sci press may be too technical, I'd prefer to make this more for the community than for linguists (although hopefully both, nice that it can be in LaTeX).
I tried Mac publisher, but the interface is very annoying ... Ideally there is an opportunity (even in a vanity press) to submit in LaTeX. But maybe some of you guys have experience with this.
