Unless someone knows of a map that does this for the entire world. If such a map exists, it should rule over all other maps.
Clearly, I have found a map that makes me happy. It shows locations for bookstores for most of the U.S. including Hawai’i and even a few in Canada. For about half of the states, there are so many bookstores you can only make an educated guess at which state you are looking at. Nice! You can find it here: https://www.iheartbookstores.com/
Here is an article that talks about the map: https://lithub.com/never-get-stranded-without-a-novel-again-with-this-map-of-6000-bookstores/. I recommend checking out their Literary Atlas of America as well. Happy exploring!
