Received a query from an Eva Díaz-Ceso who runs a small Spanish publishing company regarding wanting to acquire Spanish rights to my work. Tried to Google her, but Spanish is not a language I can even limp in. Google-fu fail. Anyone heard of her? Worked with her?
It's not exactly genre. I know the co-editor, Paz, better (we see each other at local poetry events from time to time).
It's an innovative 'zine exploring alternative formats, etc.
Doesn't pay anything, as far as I know.
Not sure if Eva is working now on a different project, though, so do find out what it is she wants (just a story? the entire collection?) and for which group.
As Aliette says, there is very little genre publishing in Spain, almost none of which pays, so it's not like granting limited rights for copies (or just royalties without an advance in the case of a book) is preventing you from selling rights for cash to a prozine (or a larger publisher who would do the collection, especially since collections are very hard to place, especially genre ones, and especially in translation)...
According to this she's a young entrepreneur (and a radio site said she started as a poet and has moved into the business side). http://noticiasliterarias.bitacoras.com/archivos/2008/04/15/jose-ivan-suarez-en-dulce-arsenico Pictures here: http://www.dulcearsenico-enpapel.blogspot.com/ Her magazine looks like it's poetry and art. You can pay for sample copies (which really doesn't help).
I'd ask her for more information about her background. I'm happy to help with Spanish should you need it (as long as you don't want it spoken or written - these days I read it only).
