Garfield's Institute for Scientific Information passed through Thomson to become the private-equity-owned, publicly traded Clarivate

The scholarly-citation infrastructure that began as Eugene Garfield's Institute for Scientific Information (ISI) is now owned by a for-profit, publicly traded holding company. ISI was acquired by Thomson in 1992, folded into what became Thomson Reuters' Intellectual Property & Science division, and then in 2016 sold to the private-equity firms Onex Corporation and Baring Private Equity Asia, which rebranded the business Clarivate (later listed as NYSE: CLVT). The same corporate entity now owns Web of Science, the Journal Citation Reports (home of the impact factor), EndNote, and the Highly Cited Researchers list.

This ownership chain is the political-economy layer beneath the vault's bibliometrics cluster: the citation metrics that govern scientific prestige are products sold by a private-equity-originated corporation, not neutral public infrastructure. It is what makes the credential in claim-saudi-universities-bought-clarivate-highly-cited-researcher-status purchasable — the vendor sells rank as a product — and it reframes claim-garfield-warned-impact-factor-unfit-to-judge-individuals: a tool one scientist built to trace scholarly influence now sits inside a commercial holding company. The structural critique behind claim-dora-2013-declaration-rejects-impact-factor-for-research-assessment gains force once the evaluative metric is also someone's revenue line.
