Many of Italy’s provincial archives have YouTube videos on the internet which can give you a unique glimpse into their archives and a view of the materials not often seen by the average researcher. Below are links to a few videos that I thought you would find interesting.
The Archivio di Stato di Milano and the Archivio di Stato di Torino also have their own Youtube channels. You can search for the channel by name.
Many also have their own Facebook page where you can ask questions and find out how to reserve materials for your onsite research trip. Good luck in your research!
