Lists of OA repositories can be found, for instance, on OpenDOAR and in the Registry of Open Access Repositories.
With OpenAire (Open Access Infrastructure for Research in Europe), the European Commission implements a technical infrastructure for achiving research data.
The European Open Science Cloud (EOSC) was opened on 23 November 2018.
In cooperation with CERN (European Organization for Nuclear Research), OpenAire offers the repository Zenodo.
