Three collections of texts are also available. Japanese American Relocation Digital Archive furnishes 309 documents and 67 oral histories. Free Speech Movement: Student Protest, U.C. Berkeley, 1964–1965 provides 541 documents, including books, letters, press releases, oral histories, photographs, and trial transcripts.

During World War II, the U.S. Government forced more than 100,000 Japanese Americans to leave their homes and businesses, relocating them to internment camps from California to Arkansas. Well-known photographer Ansel Adams documented the lives of Japanese Americans at the Manzanar War Relocation Center in California—from portraits to daily life, including agriculture and leisure.

This site presents 242 original negatives and 209 photographic prints, often displayed together to show Adams's developing and cropping techniques. His 1944 book on Manzanar, Born Free and Equal is also reproduced. Adams donated the collection to the Library of Congress in 1965, writing, "The purpose of my work was to show how these people, suffering under a great injustice . . . had overcome the sense of defeat and dispair [sic] by building for themselves a vital community in an arid (but magnificent) environment."

Based on a 1987 Smithsonian exhibition, this site allows visitors to click and drag through sections of text, music, personal accounts, and images that tell stories of the forced—and ultimately determined to be unconstitutional—internment during World War II of 120,000 Japanese Americans living on the West Coast. Also provides searching capabilities to retrieve images of more than 800 artifacts relating to the lives of those interned.

Sections in the narrative cover immigration, removal, internment, loyalty, service, and justice. Provides a 5,000-word audio file of interview excerpts; 6,400-word accompanying text from the 1994 traveling exhibition; annotated timeline; 72-title bibliography; 20 links to related sites; and two classroom activities. Also invites visitors to share their responses and to read those of others. Of value to students of Asian American history, the homefront during World War II, and constitutional issues.

By the time Thomas Jefferson became the third President of the United States in 1801, interest in exploring the West had begun to shape U.S. policy. This chronological narrative traces Jefferson's life, participation in politics, and accumulation of scientific geographical knowledge from 1735 to 1804. There are four main sections: "The Jeffersons and Their Frontier Virginia Neighborhood," "From Colony to Commonwealth," "Science and Statecraft at Home and Abroad," and "Public Servant to the Early Republic."

This narrative is accompanied by an archive of 169 letters, statues, books, treaties, maps, and journals providing primary source insight into Jefferson's thoughts about the West and the Lewis and Clark expedition in particular. Three interactive maps from the 1700s, overlaid with historical data about cities, private dwellings, natural features, courthouses, and waterways, provide important insight into the geographic and social environment at the time.
