Maps and atlases are items of great interest for many of us at the Scout Report. So when we came across this atlas that not only presented the cartographic history of the United States but also featured the latest interactive technology, we were ecstatic. The website offers many different entry points for visitors to explore the substantial collection of digitized maps, with the time-lapse feature being a clear favorite. We are excited to see the many ways this resource can be integrated into classroom curriculum or activities by our readers. The Digital Scholarship Lab (DSL) of the University of Richmond has recently created a digital version of a wonderful historical atlas: Charles O. Paullin and John K. Wright's 1932 Atlas of Historical Geography of the United States. Reproducing nearly 700 maps, this digitization project has enhanced the original collection and added the dramatic functionality of 21st century technology, including an amazing zoom feature. Brave visitors can start directly by Entering the Atlas, while the more cautious can view an introductory video or read over the chapter titles to find specific areas of interest. There is much to peruse, including sections on The Natural Environment and Explorations in the West and Southwest, 1535-1852. A number of maps within these sections, such as "French Explorations in the West 1673-1794," even allow for time-lapse animation. This site is a great find, especially for educators, historians, geographers, and the general map enthusiast.
