I have numerous books with charts and maps in them. In each of those resources are towns, rivers, settlements, and cultural features. These items can not be found. You search for the names of those items do come up, but it does not indicate all the maps, charts that contain those features. So, the question comes up, why did I buy these resources when I cannot find them? Your competitor LearnLogos has a resource for many books. So, why can't LOGOS do this? I was a Cartographer for 30 years and maps are my thing.
