Established in 1905, Las Vegas, NV, officially became a city in 1911. Its growth and development over the course of the 20th century is documented through this diverse collection of oral histories. Eight oral histories, in video, audio, and transcript format, expose aspects of daily life in early Las Vegas from the 1930s to the 1960s. Las Vegas showgirls Anna Bailey, Carol Baker, Betty Bunch, Sook-ja, Ai-ja, Mia Kim, and Virginia James discuss working conditions on the Las Vegas strip in the 1960s and 70s as well as their involvement with prominent shows, the racial integration of showrooms, and the growth of the Las Vegas Korean community. Present-day Las Vegas comes to life through oral histories and videos of six women in their 70s and 80s who tap dance together several times a week at the West Las Vegas Arts Center. Segregation, integration, the Nevada Test Site, and local history in Las Vegas are the focus of the oral history roundtable with Rose Hamilton and four other women who grew up together in Las Vegas and remain friends to this day.

In commemoration of the 1848 California Gold Rush, the Oakland Museum opened a series of exhibitions and created this online companion site. Sponsored by Kaiser Permanente, this virtual tour of the museum's exhibition offers an extensive (roughly 5,000-word) narrative of the Gold Rush and its history, illustrated with over 50 images of posters, photographs, artifacts, and art related to the Gold Rush. Three audio narratives discuss details of the discovery of gold and the resulting massive westward migration. Also included on the site are 28 images of artwork and 22 photographs of related subjects.

Site visitors can explore the experiences of Chinese, Latino/Californio, Native American, and African American peoples who participated in the Rush. Links to three curriculum sites and sample curriculum materials are available for grades 4, 5, 8, and 11; five curriculum units and 18 lesson plans can be purchased from the museum. The site is ideal for researching California history and westward expansion.

This site offers a large archive of selected documents, reports, records, maps, photographs, newspapers, artifacts, and oral history interviews. Items are searchable by ethnic group, keyword, archive, type of material, date, or subject. Brief historical overviews and bibliographies for each ethnic group profiled are also available in the archive section. Another section has lessons plans for teachers on African Americans, immigration and settlement, migration, and ethnic culture and identity, 1850-1950. It also offers tutorials on using the archive, using history databases on the web, interpreting photographs, interpreting documents, and interpreting oral history. Historical overviews are provided on the various ethnic groups that settled the Columbia River Basin.

A discussion forum offers a place to talk about discoveries in the archive or questions. Topics currently include ethnic groups, ethnicity and race, work and labor, immigration and migration, family life, religion, social conditions, discrimination, and civil rights. A very useful site for researching or teaching the social and cultural history of the Columbia River Basin.

An adjunct site to a PBS "Frontline" program exploring the claim that Thomas Jefferson fathered at least one and maybe all of the children of his slave, Sally Hemmings. This view is supported by DNA testing and believed valid by a consensus of historians and experts. The site presents ten essays ranging from 2,000 to 5,000 words in length by prominent historians and other scholars—including Joseph Ellis, Annette Gordon-Reed, Philip D. Morgan, Jack Rakove, and Gordon Woods—on the controversy, its historical background and significance, interracial sex in the antebellum Chesapeake region, Jefferson's legacy, and America's mixed-race heritage. The site also provides accounts by four Monticello slaves and the chief overseer; four video segments, from seven to nine minutes each; transcripts of interviews with Ellis, Gordon-Reed, Dr. Eugene Foster, who designed and carried out the testing, and Lucia Cinder Stanton, from the Thomas Jefferson Memorial Foundation; and links to a clearinghouse for information that argues against the claim.
