The Berkman Center for Internet & Society has released An Evaluation of Private Foundation Copyright Licensing Policies
Here's an excerpt:
This project, a joint effort of the Berkman Center, The William and Flora Hewlett Foundation, The Ford Foundation and the Open Society Institute, with funding from Hewlett and Ford, undertook to examine the copyright licensing policies and practices of a group of twelve private foundations. In particular, it looked at the extent to which charitable foundations are aware of and have begun to use open licenses such as Creative Commons or the GPL. We surveyed foundation staff and leaders and examined a number of examples where foundations have begun to take advantage of new licensing models for materials and resources produced by their own staff, their consultants and their grantees. The complete results of our study and our comprehensive analysis and recommendations are contained in the full Report of this project.
