Mark I. Greenberg has published "Open Access Publishing in Higher Education: Charting the Challenging Course to Academic and Financial Sustainability" in the Journal of Educational Controversy.
Here's an excerpt:
The benefits, pitfalls, and sustainability of open access publishing are hotly debated. Commercial publishers dominate the marketplace and oppose alternative publishing models that threaten their bottom line. Scholars' use of open access remains relatively limited due to awareness and perceived benefits to their professional goals. Readership of open access publications is generally strong, but some people disagree that more readers leads to increased citations and research impact. Libraries have grown their influence by supporting and promoting open access, but these efforts come with significant financial costs. Today, open access has flourished most significantly as a philosophy: the belief that the world's scholarship should be freely available to readers and that publicly funded research, in particular, should be accessible to the taxpayers who paid for it.
