ATLANTA — This week marks the 150th anniversary of the Battle of Atlanta, one of the key conflicts of the Civil War, and researchers at Emory University's Center for Digital Scholarship have released a mobile app for the tour. "We developed the Battle of Atlanta mobile application in order to provide a 21st century version of the historical markers that mark sites of the Battle of Atlanta and other Civil War landmarks around the city," said Dr. Daniel Pollock, a physician, Civil War scholar and co-developer of the program. After more than two years in development, the Web-based and GPS-enabled application contains copious information about the major campaigns fought throughout the city.
