I would assume at least in the Vatican Secret Archives, where the oldest documents are kept safe and protected from people and the wear-and-tear of the outside world.
Compiling such a list would be a monumental task, to put it mildly.
The Acta Apostolicae Sedis gives you everything the Church has published from 1909 to the present. But it’s all in Latin. Each year gives about 1000 pages. And that’s just 1 century out of 20.
