The Library of Congress has a great collection of photographs from the Great Depression that has recently been updated. The collection now contains more than 175,000 portraits of America between the years 1935 and 1945, taken by photographers of the government’s Farm Security Administration. The photographs also include all known data about the subject(s) in each photo, including the date and location of the photograph and also the name of the photographer.
Thanks to a new project known as Photogrammar from Yale University, viewers will have a much easier time exploring the photographs. There’s a map that displays the images by county and another that shows where each picture was taken and by which photographer. There’s also an interactive that allows viewers to sort the photos by theme (e.g. “war” or “religion”) and then browse from there. Other tools are still in the works.
