A group of researchers at Yale created “a web-based platform for organizing, searching, and visualizing the 170,000 photographs from 1935 to 1945 created by the United States Farm Security Administration and Office of War Information (FSA-OWI).”

The platform, which they’re calling Photogrammar, allows people to use visual tools to search through the digitized photographs from the FSA-OWI archive, which is housed at the Library of Congress. The map tool, for instance, allows users to see the quantity of images made in regions across the United States. One can also use the map to trace the work of individual photographers such as Dorothea Lange, John Collier and Marion Post Wolcott, and see where they worked and produced the most images.

The Treemap, another visualization, uses colored blocks of different sizes to show the number of images of different types FSA-OWI photographers produced in different category topics. Users can drill down into subtopics of the category topics.

The Photogrammar also features a more traditional keyword-driven search function.
