Duke University has adopted an open access policy.
Here's an excerpt from "New Policy to Ease Access to Faculty Works ":
At the Academic Council meeting Thursday, faculty members passed the Duke Open Access policy proposed by the task force’s co-chairs, Cathy Davidson, Ruth F. Devarney Professor of English, and Paolo Mangiafico, director of digital information strategy. The proposal passed unanimously.
The Open Access policy provides Duke scholars with the choice of giving the University the legal basis to publish articles on a database called DukeSpace, which will be available to anyone who seeks them.
