With the adoption of an open access policy in June by the Harvard Medical School, all Harvard schools now have open access policies.
Here’s an excerpt from the announcement:
Harvard Medical School adopted an open-access policy on June 18, 2014, by a unanimous vote of the Faculty Council. The new policy covers both "quad"-based and clinical faculty. Now all Harvard schools have open-access policies.
Like the other Harvard policies, the Medical School policy insures that faculty members automatically retain a license to share their research papers freely through DASH (Digital Access to Scholarship at Harvard), the University’s open-access repository. Faculty also have the option to waive this license for any article, preserving their freedom to submit new work to the journals of their choice. When faculty write articles covered by the Medical School policy and the policy at the National Institutes of Health (NIH), they need only deposit once to comply with both.
