More than 55,000 photographs taken by staff photographers of the Chicago Daily News during the first decades of the 20th century are available on this website. Roughly 20 percent of the photos were published in the paper. The Chicago Daily News was an afternoon paper, sold at a cost of one cent for many years, with stories that tried to appeal to the city's large working-class audience.

The website provides subject access to the photographs, which include street scenes, buildings, prominent people, labor violence, political campaigns and conventions, criminals, ethnic groups, workers, children, actors, and disasters. Many photographs of athletes and political leaders are also featured. While most of the images were taken in Chicago and nearby areas, some were taken elsewhere, including at presidential inaugurations. The images provide a glimpse into varied aspects of urban life and document the use of photography by the press during early 20th century.

During the New Deal and World War II, a period marked by the impulse to capture in writing, sounds, and images significant aspects of American life and traditions, government photographers with the Farm Security Administration (FSA) and the Office of War Information (OWI) took hundreds of thousands of pictures. This website features more than 150,000 photographs from this project. The photographs document the ravages of the Great Depression, scenes of everyday life in small towns and cities, and mobilization campaigns for World War II.

This site also includes approximately 1,600 color photographs and selections from two popular collections: "'Migrant Mother' Photographs" and "Photographs of Signs Enforcing Racial Discrimination." The site also provides a bibliography, a background essay, portrait samples of 18 FSA-OWI photographers, and links to five related sites. This is a great source for studying the documentary expression of the 1930s and 1940s.

This collection of more than 1,230 images depicts the enslavement of Africans, the Atlantic Slave Trade, and slave life in the New World. Images are arranged in 18 categories, including pre-Colonial Africa, capture of slaves, maps, slave ships, plantation scenes, physical punishment, music, free people of color, family life, religion, marketing, and emancipation.

Many of the images are from 17th- and 18th-century books and travel accounts, but some are taken from sketches within slave narratives, Harper's Weekly, and Monthly Magazine. Reference information and brief comments, often an excerpt from original captions, accompany each image. Although there is no interpretation or discussion of historical relevance, these images are valuable for learning about representations of slavery in American slave societies, especially in the Caribbean and Latin America.
