I've long been a fan of the eclectic literature put out by the fine Dalkey Archive, a non-profit press based at the University of Illinois whose aim to is to keep fine books in print and bring them to a wider audience; a significant chunk of their list is the sort of wonderful literature in translation most publishers don't see enough money in publishing, but which we are poorer for not having available to us. Also, how can you not love a publisher who takes their name from the work of Flann O'Brien?
One thing I haven't particularly admired in the past has been Dalkey's covers: they've tended towards the dull but worthy. But recently they've been having a bit of an overhaul under the artistic direction of one Danielle Dutton, with illustrator Nicholas Motte providing bold pen-and-digital sketches with large areas of flat colour, giving the books a unified, striking look.
As you can see, they're about to republish A Nest of Ninnies by James Schuyler and John Ashberry. If you haven't read the two brilliant novellas by Shuyler already available from NYRB...
..then you must go and get them and read them NOW.
