The report describes a project to get more Danish journals included in DOAJ. The project was initiated in autumn 2020 and started in January 2021. The background has been to strengthen communication, collaboration and knowledge sharing across university libraries within the Royal Danish Library, but also to collaborate nationally with other university libraries that work with OJS servers (Aalborg University Library and Copenhagen Business School). The initiative has been initiated to increase the quality and visibility of the Royal Danish Library Open Science services as well as strengthening the OA journals in terms of visibility and traffic.Rapporten beskriver et projekt, der skulle få flere danske tidsskrifter optaget i DOAJ.
