Supposedly?? I am no expert on Napoleon but having done some theology I can assure you that Napoleon books have a long way to go in terms of numbers.
I don’t know that you having done some theology is a basis for comparison. I was repeating the conclusion of multiple newspaper and magazine articles I’ve read. Certainly any such conclusion is going to be based on estimation since no one has a catalog of all books written to-date, and therefore by its very nature any such conclusion is “supposedly”. Of all the points in this thread that really deserve additional discussion, I don’t follow why you are concerned about this specific one, but if I run across one of the magazine articles that reported such today, I’ll post the citation for you…
