The Netherlands: Publishing in Open Access increases usage and has no effect on book sales

 OAPEN-NL’s final report, published yesterday, gives recommendations for research funders, libraries, publishers and authors. (...) In total 50 academic books were published in Open Access with subsidy from NWO. (...) OAPEN-NL also gathered data of all 50 books to get an insight in the costs related to publishing academic books. Based on this research, publishing a monograph in the Netherlands costs an average of € 12,000. Roughly half of these costs are for the Open Access edition. Remaining costs regard printing and disseminating the paper version. These results are important for the funding of Open Access monographs in the Netherlands.
