Prepositions are still very difficult for me.
Why is "on" used instead of "in" in this sentence?
This library has the definitive collection of books on ancient Egypt.
I have no idea. Why is that?
Thanks for your help in advance.

This 'on' is basically short for 'on the subject of ...'
a collection of books on ancient Egypt = a collection of books on the subject of ancient Egypt
a collection of books in ancient Egypt = a collection of books which is physically located in Egypt
