The Confederation of Open Access Repositories has released Incentives, Integration, and Mediation: Sustainable Practices for Populating Repositories.
Here's an excerpt from the announcement:
There is an active, thriving community of open access repositories worldwide and their visibility is rising as funding agencies and governments implement open access policies. Still, repositories must continue to adopt strategies that demonstrate their value to the wider research community. Therefore COAR has now published the report, "Incentives, Integration, and Mediation: Sustainable Practices for Population Repositories". It profiles a variety of successful practices for populating repositories from around the world. Aim of the report is to assist the global repository community in implementing sustainable methods for recruiting content. The profiles were gathered from organizations across the globe, and represent a mixture of approaches involving the introduction of incentives; integration of the repository with other institutional services; and/or mediation of the deposit process. The practices reflect a tradition of innovation and openness in the repository community, and are characterized by creative approaches to staffing, imaginative software developments, and adoption of novel policies.
