As many have found out in recent months (if not years), resources to support making the case for research data management are thin on the ground. We have started a collection here, some of which we have produced ourselves and some of which have been suggested by others. If you're aware of any resources not listed below please login and suggest an edit. Alternatively, contact firstname.lastname@example.org.
