Disturbed by rising costs for publications, for a long time Digitization should lower cost Convinced business model must change, no more big deals CWI plays a special role in mathematics, has top library Lots of policy papers, but where is the real progress? 2

What can CWI do? Do not subscribe to VSNU deals with commercial publishers Own repository linking to NARCIS All CWI pubs full text in repository, so 100% open access at zero cost Active (inter)nationally (ERCIM) 3
