It takes some digging, but Internet Archive appears to have the entire edition of Thomas Aquinas’s Summa Theologica translated by the Fathers of the English Dominican Province (London: Burns, Oats, and Washbourne, 1913–1929). Links to the individual volumes are below. Comments are certainly welcome if anyone notices a volume(s) that I’ve missed out.
