The printing costs of theses published within the Casimir Research School are in general partly covered by funding agencies such as FOM and NWO or at Leiden by the University. However, this financial support might not cover the full printing costs. Within Casimir is has been agreed that the following rule will be implemented: research groups (not the Casimir Research School) will co-support the printing of theses up to a maximum of 2000 euros per thesis. This implies that PhD students only need to pay printing costs exceeding 2000 euro themselves. Please note that funding options such as FOM should still be applied for: the research groups will further contribute to this amount towards a maximum of 2000.
