Kottke.org weist unter dem Titel «Photos of the Great Migration» auf einen neuen Beitrag der Library of Congress hin, der erklärt, wie man Fotos von der grossen Abwanderung in Amerika findet:
«During the Great Migration, from about 1915 to 1970, millions of African Americans moved from southern, primarily rural areas of the United States to urban areas to the north and west. They sought better opportunities away from racial discrimination and violence in the South. This guide provides strategies for searching the Prints & Photographs Division collections for images related to this movement, because the designation “Great Migration” appears in very few descriptions of pictures.»
