A new report from the DIAMAS (https://diamasproject.eu/) work package that SPARC Europe leads looks at understanding how institutional publishing is sustained today. Institutional publishers and service providers are diverse due to their missions, size and service provision. In addition, there is no definitive set of tasks that all institutional publishers share. These characteristics influence the sustainability options available to them and the choices they make.

Institutional Diamond OA publishers have a clear view of their challenges: a lack of financial resources and stability and permanence in personnel, and a dependence on parent organisations. They also share a vision of a Diamond OA funding landscape that rejects author-pays solutions, reinforces the need for continued financial support from public bodies and institutions, and research funding organisations that have largely been absent to date.
