There is a nice scan of Santiago Ramirez, O.P.'s article "The Authority of St. Thomas Aquinas" available at the Internet Archive (here). Ramirez's piece appeared in the January issue of The Thomist in 1952. Another scan of it had been online for a while (I can't remember where now) but the one at the Internet Archive is far superior. I don't know how long it has been up there but, judging by the number of downloads (only 11 as of today), I would guess that it has not been up for very long.
