This website presents 472 black and white photographs taken by Lawrence D. Lindsley, grandson of Seattle pioneer David Denny. Born in 1878, Lindsley began taking photographs as a child, and eventually joined a photography studio in Seattle in 1903. He continued taking photographs until his death in 1974, though most of the photographs here date from the 1880s through the 1920s. In addition to photography, Lindsley held a variety of jobs in Washington State—mining, hunting, and guiding wilderness expeditions—activities all well-documented here.

The collection is especially rich in photographs of the landscape, wildlife and settlements of Mount Rainier, Grand Coulee, Lake Chelan, the Olympic Peninsula, and Old Gold Creek. Lindsley also photographed sites around King County, revealing a Seattle that had not yet experienced the urbanization of the early-20th century. A long list of subject headings reveals that Lindsley also frequently photographed family members and friends, producing images useful for examining turn-of-the-century portraiture.

This site presents more than 1,000 original panoramic maps, "a popular cartographic form" during the late 19th and early 20th centuries. The maps, often prepared for civic organizations, such as chambers of commerce and real estate agents, to promote an area's commercial potential, cover the contiguous 48 states and four Canadian provinces of British Columbia, Nova Scotia, Ontario, and Quebec between 1847 and 1929. While most of these maps were not drawn to scale, viewers can zoom in to find artists' renderings of individual streets, buildings, and landscape features. The site also includes a 1,200-word history of panoramic mapping; a bibliography comprised of 24 titles; and background essays (1,000 words) and images relating to five prominent panoramic artists: Albert Ruger (1829-1899), Thadeus Mortimer Fowler (1842-1922), Oakley H. Bailey (1843-1947), Lucien R. Burleigh (1853-1923), and Henry Wellge (1850-1917). This site is an excellent resource for those studying urbanization, cities, business growth, and the art of mapmaking.

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.

More than 30,000 photographs of Colorado towns, landscapes, mining scenes, and American Indian tribes, taken between 1860 and 1920, are featured on this website. Approximately 4,000 images deal with the mining industry, including labor strikes, while 3,500 photographs depict Indian communities from more than 40 tribes west of the Mississippi River.

Provides 14 links to additional sheet music collections and reference sources. These resources are valuable to those studying popular culture, California history, music history, advertising, and depictions of ethnicity, gender, and race in 19th-century America.

Significant European migration into the Ohio River Valley occurred from the mid-18th century to the early 19th century and this website presents approximately 15,000 pages of related materials. Resources include books, pamphlets, newspapers, periodicals, journals, letters, legal documents, images, maps, and ledgers. The site includes a special presentation with a 6,500-word essay on contested lands, peoples and migration, empires and politics, Western life and culture, and the construction of a Western past.

Materials address encounters between Europeans and native peoples, the lives of African American slaves, the role of institutions such as churches and schools, the position of women, the thoughts of naturalists and other scientists, and activities of the migrants, including travel, land acquisition, planting, navigation of rivers, and trade. These are valuable resources for studying early American history, cross-cultural encounters, frontier history, and the construction of the nation's past.
