1. Mathematics in Open Access

General Director CWI
Professor at ILLC, UvA

2. 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

3. 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
