Richard Poynder has published "The OA Interviews: Alison Mudditt, Director, University of California Press" in Open and Shut? in which Mudditt discusses the UC Press' Collabra and Luminos open access programs.
Here's an excerpt:
Collabra's model speaks to publishers, libraries, funders, and researchers who are seeking more cost transparency and greater recognition of the critical role that the academic and scientific community plays in journal publishing. In our model, the people who do the fundamental work of peer-review are recognized for this and are able to decide where to place that value.
