Covering the years from 1848 to 1921, this website presents materials from the suffrage movement in America, including 167 books, pamphlets, handbooks, reports, speeches, and other artifacts totaling some 10,000 pages. Formed in 1890 from two rival groups, the National American Woman Suffrage Association (NAWSA) orchestrated passage of the 19th Amendment in 1920 through state campaigns. Materials include works by Carrie Chapman Catt, the Association's longtime president, as well as from other officers and members, including Elizabeth Cady Stanton, Susan B. Anthony, Lucy Stone, Alice Stone Blackwell, Julia Ward Howe, Elizabeth Smith Miller, and Mary A. Livermore. There are two bibliographies, an essay on Catt, a timeline, and links to 18 related collections, most of them associated with the Library of Congress American Memory.

Hundreds of documents and thousands of images relating to World War I, with particular emphasis on military, diplomatic, and political resources, are available on this website.

The website also offers substantial sections on the maritime war and the medical front, an alphabetical bibliographical dictionary with over 200 names, and approximately 125 links to related sites. The authors—volunteers from a World War I electronic discussion network—encourage user participation in expanding the site.

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).

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.

These varied collections document the history of Los Angeles and southern California. "Digital Archives" offer more than 126,000 photographs, maps, manuscripts, texts, and sound recordings in addition to exhibits. Nearly 1,200 images of artifacts from early Chinese American settlements in Los Angeles and Santa Barbara are available, as is the entire run of El Clamor Publico, the city's main Spanish-language newspaper from the 1850s. Photographs document Japanese American relocation during World War II and photographs, documents, and oral history audio files record Korean-American history. The archive also includes Works Projects Administration Land Use survey maps and Auto Club materials. A related exhibit, "Los Angeles: Past, Present, and Future", offers collections on additional topics, including discovery and settlement, California missions, electric power, "murders, crimes, and scandals," city neighborhoods, cemeteries, Disneyland, African American gangs, and the Red Car lines.

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.
