Chris Armbruster has self-archived "Implementing Open Access: Policy Case Studies" in SSRN.
Here's an excerpt:
A first generation of open access policy development and implementation is coming to a close. It is thus possible to begin evaluation. Evaluating implementation establishes evidence, enables reflection, and may foster the emergence of a second generation of open access policies.
This study is based on a small number of cases, examining the implementation of open access around the world. Some of the pioneer institutions with open access mandates have been included, as well as some newer cases. The emergence of the new stakeholders in publishing is examined, such as digital repositories, research funders and research organisations.
Because this is a groundbreaking study, no claim is made that the results are representative. The emphasis is on variety and on defining a methodological standard. Each case is reconstructed individually on the basis of public documents and background information, and supported by interviews with professionals responsible for open access implementation.
