On November 15, 2010, the Harvard Divinity School adopted an open access policy. Five other Harvard units have an open access policy: the Business School, the Faculty of Arts and Sciences, the Graduate School of Education, the Kennedy School of Government, and the Law School.
Here's an excerpt:
The Faculty of the Harvard Divinity School is committed to disseminating the fruits of its research and scholarship as widely as possible. In keeping with that commitment, the Faculty adopts the following policy: Each Faculty member grants to the President and Fellows of Harvard College permission to make available his or her scholarly articles and to exercise the copyright in those articles. More specifically, each Faculty member grants to the President and Fellows a nonexclusive, irrevocable, worldwide license to exercise any and all rights under copyright relating to each of his or her scholarly articles, in any medium, provided that the articles are not sold for a profit, and to authorize others to do the same. The policy applies to all scholarly articles authored or co-authored while the person is a member of the Faculty except for any articles completed before the adoption of this policy and any articles for which the Faculty member entered into an incompatible licensing or assignment agreement before the adoption of this policy. The Dean or Dean's designate will waive application of the license for a particular article or delay access for a specified period of time upon express direction by a Faculty member.
Each Faculty member will provide an electronic copy of the author's final version of each article no later than the date of its publication at no charge to the appropriate representative of the Provost's Office in an appropriate format (such as PDF) specified by the Provost's Office. The Provost's Office may make the article available to the public in an open-access repository.
