A companion site to the four-part PBS series that began airing in October 2001 "to explore the roots of American music . . . Blues, Country, Bluegrass, Gospel, Cajun, Zydeco, Tejano, and Native American." Includes excerpts (from 1,500 to 6,000 words) from eight oral histories with important artists, including James Cotton, Bela Fleck, Arlo Guthrie, Buddy Guy, Flaco Jimenez, B. B. King, Alan Lomax, and Willie Nelson. Also provides profiles of up to 1,000 words each of 96 artists, 15 songs, and 5 instruments.

A Teacher's Guide includes four lessons geared to middle and high school social studies and history courses on "Finding the Story in the Song," "Desegregating the Airwaves: Blues on the Radio," "Gospel Music Meets a Wide Audience," and "The Strength of Native American Music."

This guide offers photos of some of the artists (but no audio files), a 120-title bibliography, and links to 28 related sites, but in its 2,000-word introduction fails to explain the reason that these particular types of music—and not other musical styles—have been defined as comprising the "roots of American music." Despite this vagueness of definition, the site will be valuable to students of American music and 20th-century cultural history for what it does include.

This site features 35 hours of folk and popular music sound recordings from several European, Slavic, Middle Eastern, and English- and Spanish-speaking communities. The Work Projects Administration California Folk Music Project collected these 817 songs, in 12 languages and representing 185 musicians, in Northern California between 1938 and 1940. The collection also includes 168 photographs of musicians, 45 scale drawings and sketches of instruments, and numerous written documents, including ethnographic field reports and notes, song transcriptions, published articles, and project correspondence.

Organized by folk music collector Sidney Robertson Cowell, sponsored by the University of California, Berkeley, and cosponsored by the Archive of the American Folk Song, this was one of the earliest ethnographic field projects to document folk and popular music of such diverse origin in one region. In addition to folk music of indigenous and immigrant groups, the collection includes popular songs from the Gold Rush and Barbary Coast eras, medicine show tunes, and ragtime numbers. In addition, short essays describe the California Folk Music Project and the ethnographic work of Sidney Robertson Cowell. This collection is an excellent resource for learning about ethnographic research practices as well as about cultures of various California ethnic groups.

Offering 16 separate databases of digitized materials, this website provides firsthand accounts (diaries, letters, and memoirs) and literary efforts (poetry, drama, and fiction). Twelve databases pertain to American history and culture.

"Early Encounters in North America: Peoples, Cultures, and the Environment" offers primary sources documenting cultural interactions from 1534 to 1850. "The American Civil War: Letters and Diaries" draws on more than 400 sources and supplies a day-by-day chronology with links to documents. "Black Thought and Culture" furnishes monographs, speeches, essays, articles, and interviews. "North American Immigrant Letters, Diaries, and Oral Histories" covers 1840 to the present. "North American Women's Letters and Diaries: Colonial to 1950" provides full-text letters and diaries from more than 1,000 women—totaling more than 21,000 documents and approximately 120,000 pages—written between 1675 and 1950.

Five databases present American literary writings: "Latino Literature"; "Black Drama"; "Asian American Drama"; "North American Women's Drama"; and "American Film Scripts Online." In addition, "Oral History Online" provides a reference work with links to texts, audio, and video files. While the databases include previously published documents, many also contain thousands of pages of unpublished material. In addition to keyword searching, the databases provide "semantic indexing"—extensive categorical search capabilities.
