Nearly 4,000 panoramic photographs of cityscapes, landscapes, and group portraits, deposited as copyright submissions by more than 400 companies, are displayed on this site. Panoramic photographs were used to advertise real estate and to document groups, events, and gatherings. Images depict all 50 states, the District of Columbia, and more than 20 foreign countries and territories. Subjects include cityscapes, landscapes, group portraits, agricultural life, disasters, education, engineering, fairs and expositions, industrial scenes, military activities, performing arts, sports, and transportation. Although the images cover the period from 1851 to 1991, the collection centers on the early 20th century. The site includes a bibliography, an illustrated 1,000-word background essay on the history of panoramic photography, and an essay outlining the technicality of shooting a panoramic photograph. Four essays focus on specific photographers: George R. Lawrence (1869–1938); George N. Barnard (1819–1902); Frederick W. Brehm (1871–1950); and Miles F. Weaver (1879–1932).

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.
