The University of Groningen has launched a stimulus fund to support diamond open access initiatives by UG/UMCG researchers.

The fund can be used to expand and improve existing initiatives (e.g. professionalizing or scaling-up a scholar-led journal) or to create new ones (e.g. setting up a new journal or flipping an existing journal to diamond open access).

The University of Groningen Library also financially supports various diamond open access initiatives and open access infrastructures.

Diamond open access initiatives
