I was just going to write a question, but then I thought that an generalised canonical Q&A might be better; then I had a second thought that there might already be such a resource but I hadn't found it.
So I decided to ask here first.
I have wondered what should happen to the historical material I have collected over the years, because if I do not ensure it is preserved I am certain it will be destroyed by those who come after me. A problem for many of us with many years of experience that span back to the origins of computing technology.
I have a lot of manuals about hardware and software as well as hardware artefacts. The manuals can go back to the early 1950s, cover 60s, 70s, 80s and so on.
Perhaps they are not unique, but who knows.
Any thoughts if such a general question would be useful on the site?
