Migration, both forced and voluntary, remains a prominent theme in African American history. This website is built around the history of 13 African American migration experiences: the transatlantic slave trade (1450s–1867), runaway journeys (1630s–1865), the domestic slave trade (1760s–1865), colonization and emigration (1783–1910s), Haitian Immigration (1791–1809), Western migration (1840s–1970), and Northern migration (1840s–1890).

Twentieth-century migrations include the Great Migration (1916–1930), the Second Great Migration (1940–1970), Caribbean immigration (1900–present), the return South migration (1970–present), Haitian immigration in the 20th century (1970–present), and African immigration (1970–present). More than 16,500 pages of texts, 8,300 illustrations, and 67 maps are included. An interactive timeline places migration in the context of U.S. history and the history of the African Diaspora.

These materials examine Depression-era migrant work camps in central California. The Farm Security Administration (FSA) managed the camps that were primarily inhabited by migrants from the rural areas of Oklahoma and nearby states. The collection of materials include 371 audio recordings of songs, interviews, and camp announcements and transcriptions of 113 songs. Print and image materials include 23 photographs, newspaper clippings, and 11 camp newsletters.

Additional materials address the role of the ethnographer, including a Works Progress Administration folk song questionnaire; the field notes and correspondence of Charles L. Todd and Robert Sonkin, the original collectors of the materials; and two published magazine articles by Todd. Topics range from camp court proceedings and personal narratives to square dances and baseball games. The website also includes a bibliography, a background essay, and an essay on the recording expedition. This is a valuable site for the study of Depression-era migrants, their folk traditions, and the documentary impulse of the period.

During the New Deal and World War II, a period marked by the impulse to capture in writing, sounds, and images significant aspects of American life and traditions, government photographers with the Farm Security Administration (FSA) and the Office of War Information (OWI) took hundreds of thousands of pictures. This website features more than 150,000 photographs from this project. The photographs document the ravages of the Great Depression, scenes of everyday life in small towns and cities, and mobilization campaigns for World War II.

This site also includes approximately 1,600 color photographs and selections from two popular collections: "'Migrant Mother' Photographs" and "Photographs of Signs Enforcing Racial Discrimination." The site also provides a bibliography, a background essay, portrait samples of 18 FSA-OWI photographers, and links to five related sites. This is a great source for studying the documentary expression of the 1930s and 1940s.
