Heather Joseph has published "The Open Access Movement Grows Up: Taking Stock of a Revolution" in a special issue on open access of PLOS Biology.
Here's an excerpt:
Overall, the story of the OA movement over the past ten years has been one of demonstrable progress. To be sure, the road has not been a smooth one. There have been stumbles, wrong turns, false starts, and bruising battles, particularly in the policy arena. But if we weigh the indicators of progress made by the OA movement against the intensity and complexity of the obstacles it has faced in the first decade, there's reason for great optimism as we head into the next ten years.
