The Detroit Publishing Company mass produced photographic images—especially color postcards, prints, and albums—for the American market from the late 1890s to 1924. This collection offers more than 25,000 glass negatives and transparencies and about 300 color photolithographs from this company. It also includes images taken prior to the company's formation by landscape photographer William Henry Jackson, who became the company's president in 1898. Jackson's work documenting western sites influenced the conservation movement. Although many images were taken in eastern locations, other areas of the U.S., the Americas, and Europe are represented. The collection specializes in views of buildings, streets, colleges, universities, natural landmarks, and resorts, as well as copies of paintings. Nearly 300 photographs were taken in Cuba during the Spanish-American War. About 900 Mammoth Plate Photographs include views of Hopi peoples and their crafts and landscapes along several railroad lines in the 1880s and 1890s.

This annotated collection of more than 30 letters addresses the personal and political costs of war. Letters cover conflicts from the Revolutionary War to the current war in Iraq and are divided thematically into five sections: "Enlisting," "Comforts of Home," "Love," "Combat," and "The End of the War." Letters come from well-known military figures, such as Douglas MacArthur and Robert E. Lee, as well as ordinary veterans, such as Peter Kiterage, one of the 5,000 African Americans who fought in the Revolutionary War. The thematic organization allows users to chart changes and continuities over 200 years of American history. Each letter is read aloud so students can listen as well as read. In addition, a "magic lens" feature provides transcriptions over the original handwriting to help students decode the letters.

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.

James Allen has assembled a collection of chilling photographs of lynchings throughout America, primarily from the late 19th and early 20th centuries. Many were circulated as souvenir postcards. The site is a companion to Allen's book Without Sanctuary. The exhibit can be experienced through a flash movie with narrative comments by Allen or as a gallery of more than 80 photographs with brief captions. Most images also have links to more extensive descriptions of the circumstances behind each specific act of violence.

While the vast majority of lynching victims were African Americans, white victims are also depicted. Individually and as a group, these images are disturbing and difficult to fathom. They provide, however, an excellent resource for approaching the virulence and impact of racism in late 19th and 20th-century America.

A 1,000-word essay describes the letter collection and the lives of the principal correspondents. Biographical notes are available for more than 120 of the people who corresponded with the Oblingers or who were mentioned in the letters.
