Accuracy in mapping is crucial, and during the Civil War in the United States this important skill was vital to a successful campaign. In one of its most ambitious digital collections to date, the American Memory project at the Library of Congress has placed approximately 2240 Civil War maps and charts in this archive, along with 200 maps from the Library of Virginia and 400 maps from the Virginia Historical Society. Visitors can jump right in by browsing the entire collection by place, subject, creator, or title. Some real gems include the multitude of maps and views of Vicksburg in Mississippi and those of the infamous Andersonville Prison in Georgia. The site also contains a number of classroom resources for educators, and a very nice essay (divided into seven sections) by Richard W. Stephenson that explores the history of mapping the Civil War.
