American Panorama 
American Panorama is an historical atlas of the United States for the twenty-first century. It combines cutting-edge research with innovative interactive mapping techniques, designed to appeal to anyone with an interest in American history or a love of maps.
Working with the Digital Scholarship Lab at the University of Richmond, and sponsored by the Mellon Foundation, we’ve designed the project to be useful to academics and scholars as they pursue research into America’s history. Specifically, the project is intended to be a source for peer-reviewed journals, so that URLs can start to be used as citations in forward-looking research.
