The Ohio State University's research now spans 80 countries

Research at The Ohio State University is a global undertaking: the university co-authors with 1,165 institutions in 80 countries, and international collaborators appear on 27% of its output.

Its largest single research relationship is with Harvard University in United States, at 2,292 joint works. Across the network, five-year output reaches 71,610 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.
