Information Today has published "Interview with Sarah Pritchard: The Changing Face of Academic Presses." Pritchard is the University Librarian at Northwestern University.
Here's an excerpt:
Q: The model that many advocate for OA books is making the text freely available online but sell the print version, so that etext will drive print sales. Do you see it as a viable model for NUP [Northwestern University Press]?
A: Absolutely, I see that as a very logical model, and I would envisage us moving to that model before we move to a totally OA environment. By the way, we are currently in the process of moving one of our journals to OA, which we are very excited about . . . TriQuarterly.
