P. Scott Lapinski, David Osterbur, Joshua Parker and Alexa T. McCray have published "Supporting Public Access to Research Results" in College & Research Libraries.
Here's an excerpt:
We posed the question of what services an academic library can best provide to support the NIH Public Access Policy. We approached the answer to this question through education, collaboration, and tool-building. As a result, over the last four years we have engaged over 1,500 participants in discussions of public access to research results, forged alliances with dozens of partners, and built online tools to ease the process of complying with the NIH policy. We conclude that librarians working in collaboration with other key constituencies can have a positive impact on improving access to the results of scientific research.
