Jahn N, Tullney M. A study of institutional spending on open access publication fees in Germany. PeerJ 2016;4:e2323
This study examines how much German universities and research organisations spent on open access publication fees. According to self-reported cost data from the Open APC initiative, this type of support has grown over the years. Comparing these expenditure with those from Austria and the UK, German open access funding is focused primarily on fully open access journals, raising important questions about hybrid open access journals as a publication venue.
