@n8chz @foo I think I still have a notepad somewhere with carbon sheets in between normal paper ones, so when you write something down, you have a copy straight away ๐
I was too young to do any publications, but I was born in USSR, my mom worked at a research institute and she had plenty of these carbon sheets, I think I used them for some school stuff, it was quite handy.
@n8chz @foo Of course when actual copying machines appeared in every office and using them became affordable, everyone was just: "Phew, we don't have do deal with this shish anymore" ๐
