Should this question be re-opened on the grounds that it is asking about an area of history, and it was given a successful answer?
The situation is a question that was a bit off-topic (too technical, I think. Maybe better for another site). Someone answered it, though.
The general case:
Should a closed question be re-opened if it provides info about the field of knowledge that is tagged? Or should it remain closed since it would encourage more questions in an area like this?
