Here are two old handwritten papers by Robin Milner that @jer_gib helped me track down, and a few thoughts on them. https://decomposition.al/blog/2025/11/20/where-simulation-came-from/
Where “simulation” came from

@lindsey @jer_gib I love a good library hunting story! I can't believe Oxford had a copy while Swansea didn't. If you are able to, please put them on archive.org.

@sree @jer_gib Maybe Swansea does have them in a dusty file cabinet somewhere. But anyway, good idea to put them on archive.org.
@lindsey @sree Perhaps what Swansea lacks is the dusty filing cabinet rummager. (Bracket that as you will.)
@jer_gib @lindsey My observation is that little "luxuries" like that are what distinguish the top places from everybody else.
@sree @jer_gib Libraries are a human right, but librarians are a luxury?
@lindsey
It's possible that Hindley has a copy, but I don't think he has been on campus at all in my time here at Swansea. I can maybe ask John Tucker or one of the other computing history people to stick it on cronfa
