Every country's historical and geographical information would likely be that country's important historical treasure and inheritance. This information was important enough to determine a country's survival. In the world of Eich, privately making or keeping your own maps would be considered traitorous evidence of rebellion.
Such historical and geographical information would rarely be found in public libraries or nobles' libraries. What little information that could be found would usually be rather poor or fake. The best-quality historical and geographical information would usually be kept by the royalty. It would be rare for the royalty to loan this information out to others.
I was too lazy to search by myself. I directly sent the royal palace a greeting using my real name so that it would be easy for me to get an audience.
