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.

This companion website to a PBS NOVA documentary contains information about Einstein and his theory of relativity, as well as several special features. The site offers a timeline of Einstein's life from his birth in 1879 to his death in 1955, a short essay on his life before his great discovery in 1905, and an explanation of the theory behind the equation. Special features include: an essay on the legacy of Einstein's theories of special relativity and general relativity and how they affect our world; a feature exploring time dilation as predicted by Einstein's theory of relativity; and an audio feature in which 10 top physicists briefly describe Einstein's equatio. The site also offers two teacher guides: "Einstein's Big Idea" and "Einstein Revealed," 10 links to related websites, and a bibliography of eight books. Though it contains no primary source material, this site should be useful for science teachers and high school students studying Einstein, physics, and the history of science.

A work-in-progress, this collection offers letters and diary entries by Robert "King" Carter (1663–1732), a wealthy landowner and leading public figure in Virginia. Educated in England, Carter inherited and acquired more than 300,000 acres in the Northern Neck Proprietary between the Rappahannock and Potomac Rivers. Carter, who owned nearly 1,000 slaves, served as a member of the Council of Virginia and as acting governor of the colony.

The site presently contains transcripts of all existing Robert Carter texts, including approximately 800 letters, written between 1701 and 1727, diary entries covering 1722–1726, and wills. Each document provides both modern and original spellings, and hyperlinked notes offering identifying information for more than 130 persons, places, and things. A 2,200-word biography of Carter, a 2,100-word essay on the Northern Neck Proprietary, and a bibliography of nearly 80 titles are also available.

Each issue includes poetry, engravings, and articles, as well as a section on Victorian fashion. In addition to these full issues, the site also includes a Samples Collection, which features selections from the Book during the years 1855-1858. These samples are divided into six main categories, each of which is further broken down to make the content more accessible. Overall, this is a useful resource for teachers and students interested in aspects of Victorian popular culture.

Kansas City's Local 627, one of several African American musicians' unions affiliated with the American Federation of Musicians, was founded in 1917. This website traces its history over the course of the 20th century. This history is divided into nine chronological sections, including introduction to the roots of Kansas City jazz style, early jazz bands, bigger bands and a new headquarters for the organization, jazz during World War II, the thriving music scene in the 1950s, the merger with Local 34, and the efforts of the Mutual Musicians Foundation to promote jazz in the 1960s and 1970s.

Upon entering each section, visitors are greeted by a video presentation of photographs of prominent Kansas City musicians and newspaper articles documenting their accomplishments, accompanied by a jazz soundtrack. In addition to explanatory text introducing musicians and prominent events in Kansas City history, each section also includes roughly 20 photographs, as well as a few songs of the era, which can be listened to using RealPlayer. Useful for those interested in Kansas City history or in U.S. music culture in the 20th century more generally.
