The Association of American University Presses has released Digital Publishing in the AAUP Community; Survey Report: Winter 2009-2010.
Here's an excerpt:
In October–November 2009, AAUP surveyed its member presses about digital publishing strategies and programs. The survey had two purposes. This report shares the responses to seven questions specifically about digital strategies, technologies, and concerns related to their book publishing programs. The survey also collected new and updated information on specific e-publishing programs at member presses in order to update the association’s online directory of such projects.
