A fair few searches brought me only html pages of J.-L.-C. Sismondi’s Political Economy, but personally I like PDFs. So I compiled one, and here it is, in case this is something you’d want as well.
This might not be the last time I do this sort of thing, whether or not there’s external interest. But if you definitely do want more, please let me know and don’t hesitate to make requests.
Cheers!
