Did you have an example?
See an example list

I find it hard to believe, can't you at least you
can say where it is
(at the minimum the country and idealy the city, the coordinates, etc.).
Coordinates absolutely not. City is not trivial, the institution holding
the item may be anywhere. Country is probably easier, we only need to
check for San Marino and Vatican :) ; but that's basically noise,
doesn't say anything useful about the thing.
