Yale’s Photogrammar Interactive Map is a great way to find photographs by county – the darker shade of green your county is, the more photographs are available.
When you find a photograph you are interested in be sure to click on the “Call Number (Library of Congress)” about halfway down the left side of the screen to see a higher definition image or download in different formats.
