Rita Pinhasi et al. have published "The Weakest Link—Workflows in Open Access Agreements: The Experience of the Vienna University Library and Recommendations for Future Negotiations" in Insights.
Here's an excerpt:
In recent years open access (OA) publishing agreements have left a lasting impact on several aspects of the research life cycle, and on the manner in which institutions work with publishers and researchers to support the transition to OA. Apart from the immediate financial implications, one significant challenge libraries are facing is the sub-optimal level of workflow infrastructure that could determine the success or failure of otherwise innovative approaches. This article will examine the Vienna University Library’s hands-on experience with OA agreements and the implementation of relevant workflows. It will describe existing workflows, review the benefits of the various systems in place and identify areas for improvement. The paper will also propose items for discussion for organizations when negotiating OA agreements with publishers and will highlight potential pitfalls to be avoided.
