Most bibliography formats require the city of publication for books. Why? In this digital era, ISBN would be way more important. But even before the digitalization of everything, why was the city of publication important?
I can imagine some purposes:
- to distinguish potential same names of different publishers, and
- to help book-seekers find the publisher and the book by actually visiting the city or contacting libraries in the city.
I want to know better stories about the 'city of publication'.
