Furnishes 64 photographs taken by Lewis W. Hine (1874–1940) between 1908 and 1912. Images document American children working in mills, mines, streets, and factories, and as "newsies," seafood workers, fruit pickers, and salesmen. The website also includes photographs of immigrant families and children's "pastimes and vices."

Original captions by Hine—one of the most influential photographers in American history—call attention to exploitative and unhealthy conditions for laboring children. A background essay introduces Hine and the history of child labor in the United States. This is a valuable collection for studying documentary photography, urban history, labor history, and the social history of the Progressive era.

In 1917, a labor dispute between copper mining companies and workers in Bisbee, Arizona, escalated into vigilante action against suspected members of the Industrial Workers of the World (IWW). This site provides primary and secondary sources on the strike and subsequent deportation of over 1000 striking miners from Bisbee. It offers a roughly 500-word essay on the incident's historical context, and provides online access to materials such as personal narratives, witness interviews, government reports, newspaper articles, correspondence, and images selected from the University of Arizona Library, the Arizona Historical Society, and the Sharlot Hall Museum in Prescott, Arizona. There are 26 mining and deportation photographs, three maps, 19 IWW publications with color images of the covers, and six images of IWW stickers on the site, along with a bibliography of 34 scholarly works, 11 of which offer links to online, full-text versions. The site provides a partial finding aid that lists items with links to the document texts featured on the site. The site is ideal for studying labor action and labor/management relations in the early 20th century.

This exhibit includes 21 "actuality" films from the Library's Westinghouse Works Collection. Actuality films were motion pictures that were produced on flip cards, also known as mutoscopes. These films, made by the American Mutoscope and Biograph Company in 1904, were intended to showcase the company's operations and feature the Westinghouse Air Brake Company, the Westinghouse Electric and Manufacturing Company, and the Westinghouse Machine Company. They were shown daily in the Westinghouse Auditorium at the Louisiana Purchase Exposition in St. Louis. Brief (roughly 500-word) descriptive narratives accompany each film, along with three to five photographs of factory exteriors and interiors and male and female workers performing their duties. A timeline traces the history of the Westinghouse companies from the birth of founder George Westinghouse in 1846 to Westinghouse's last patent, awarded four years after his death in 1918. Another link offers a Wilmerding News article, dated September 2, 1904, about life in Wilmerding, Pennsylvania, "the ideal home town," where the Westinghouse Air Brake factory was located. A bibliography of 18 scholarly works on Westinghouse and manufacturing in America is also included. The easily-navigable site is keyword searchable and can be browsed by subject. It is a good resource for information on labor and manufacturing in early 20th-century America, as well as on early film.
