The DIAMAS project‘s new report, “National Overviews on Sustaining Institutional Publishing in Europe,” explores Diamond Open Access (OA) publishing in 10 European countries. It identifies how Diamond OA publishing and institutional service providers are financially sustained in specific national contexts. Key findings suggest that national contexts create unique conditions for Diamond OA publishing, with it flourishing in countries with strong community leadership and public funding. More public funding may be available for Diamond OA in countries where institutional publishers are coordinated at the national level.
