Inside The Open University's largest research partnership: University of Oxford

Behind The Open University's research output sits a defining relationship: 426 co-authored works with University of Oxford (United Kingdom) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 909 collaborating institutions across 78 countries, producing 12,284 joint works over the window, with international co-authors on 43% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.44, 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.
