Inside Dartmouth College's largest research partnership: Harvard University

Behind Dartmouth College's research output sits a defining relationship: 1,312 co-authored works with Harvard University (United States) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 980 collaborating institutions across 76 countries, producing 24,592 joint works over the window, with international co-authors on 26% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.04, where the world average is 1.0.

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.
