Funding
Read from the funding tables, never from the document count — that count includes authorship, so it ranks institutions, not funders.
What National Science Foundation has funded
56,246 awards under 18,850 distinct grant numbers, across 23,577 documents. A further 31,440 documents name it as a funder without a grant number — a weaker claim, counted separately.
