Research trend share of papers by universities & colleges in North America, per year

Each point is this institution's share of the papers credited to universities & colleges in North America that year, with credit split across co-authoring institutions. A share, not a count, because our collection grows unevenly by year. Hover a point for the figures. The hollow point is the year in progress.
