This report is the third in a series which examines issues relating to the economic sustainability of critical infrastructure services that support the operation and growth of open-access dissemination of scholarly and scientific research. This report is intended to guide funders and project planners in constructing and coordinating collective funding models capable of supporting open-access infrastructure resources. The report:
- reviews the fundamentals of robust sustainability modeling (Section 2);
- outlines the economic and institutional issues that confront those seeking to sustain free infrastructure services and discusses the implications of free models for an initiative’s ability to provide an optimal level of service (Section 3); and
- identifies strategies for overcoming institutional free ridership in the design of funding models and describes practical mechanisms for coordinating the collective provision of infrastructure services (Section 4).
