One thing I think would be very useful here is national archive data: there will be thousands of letters, memos and official documents shared between people alive back then under the care of a museum or government.

One of my dreams is to help digitise and make available the thousands of Second World War-era documents in the National Archives at Kew.

We’re at the point where a simple phone camera and a robust LLM-powered process can digitise ENORMOUS amounts of archive material almost effortlessly [1]. This is going to be enormous for historians eager to dive into the millions of interesting primary sources.
