Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 84 of the 101 answers that named Thomson Reuters ONESOURCE and are not a share of its labels.
292 of the 333 domain citations in answers naming Thomson Reuters ONESOURCE came from somebody else's page.
Pages are listed as the models cited them.
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Thomson Reuters ONESOURCE's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Thomson Reuters ONESOURCE, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at thomsonreuters.com is approved on the spot, any other address is reviewed by hand.
Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
