At last! I'm looking forward to using CENTENNIA Research Edition when my department completes the purchase ..... assuming we can fund it. Can you tell me: are the KML files compatible with Google Earth? Would I be able to show the historical borders of Europe, e.g., in 1499 displayed with the perspective and view features in Google Earth?
Hello Ellen. I have added some sample views showing Centennia KML files viewed in Google Earth.

Frank,

Another voice of acclaim for your work. I licensed the application with great delight soon after 2005.

Please add my vote to the requests for an iPad version.

With appreciation and thanks,

Your historical atlas shows details that I have never encountered anywhere else. I first discovered your maps through a viral video on youtube, and I was appalled to learn later that the video was published without attribution and violating your copyright. I hope you at least got some visitors to your site out of that. It's an astounding accomplishment and obviously a huge amount of research and artistry went into its creation.

Can you email me and let me know if you have any deals for students? I would love to be able to assign this to my students in my European History survey class this summer. Thanks, Phillip Perry, Ottawa.
Hi, Phil. Absolutely -- we do have discount pricing arrangements for students in classes, assuming you would be ordering ten licenses or more. We also have licenses for history departments and small computer labs/libraries. I'll email you.
