Erasmus University Rotterdam's research now spans 79 countries

Research at Erasmus University Rotterdam is a global undertaking: the university co-authors with 1,029 institutions in 79 countries, and international collaborators appear on 46% of its output.

Its largest single research relationship is with Radboud University Nijmegen in Netherlands, at 1,776 joint works. Across the network, five-year output reaches 27,681 co-authored works.

Connectivity of this kind is increasingly the currency of modern science, and it is measurable: the open scholarly record makes every one of these relationships public and checkable.

The Research Collaboration Index, the first global account of how universities actually collaborate, publishes its first full edition on Tuesday 15 September at 09:00 UK.

Every figure derives from the open global research record and is checkable at source.
