I've added a new feature to this site with the "My Store" option. The store has PDFs I've created based on the Twain's Geography entries. They've gone beyond what that web site contains, however, and I will need to update it with my later researches. The store uses PayPal processing functions but you don't need a PayPal account to use it. When you purchase one of these PDFs it will download the document and if your browser allows, will open it up in your PDF reader. I'd just as soon provide these for free but I need the money.
