The more than 3,500 full-text documents available on this website address the legal, economic, political, diplomatic, and government history of the U.S. Documents are divided into five time periods—pre-18th, 18th, 19th, 20th, and 21st centuries—and include treaties, presidential papers and addresses, and colonial charters, as well as state and federal constitutional and legal documents.

The materials are categorized into 64 document collections as well, such as American Revolution, Federalist Papers, slavery, Native Americans, Confederate States of America, World War II, Cold War, Indochina, Soviet-American diplomacy, and September 11, 2001. By clicking "What's New," the latest digitized documents become available. Material also can be accessed through an alphabetical list of 350 more specific categories, keyword searching, and advanced searching. Most of these documents are directly related to American history, but the site includes some materials on European and modern diplomatic history.

This ongoing project was designed to present materials on the historical experiences of those with disabilities. The website currently presents nearly 800 documents and more than 930 still images dating from the late 18th century to the present.

Subjects are organized according to categories of advocacy, types of disability, government, institutions, medicine, organizations, private life, public life, and personal names. Documents include articles, poems, pamphlets, speeches, letters, book excerpts, and editorials.

Of special interest are documents from the Roosevelt Warm Springs Institute for Rehabilitation Archives, including the Polio Chronicle, a journal published by patients at Warm Springs, Georgia, from 1931 to 1934. Images include photographs, paintings, postcards, lithographs, children's book illustrations, and 19th-century family photographs, as well as postcard views of institutions, beggars, charity events, and types of wheelchairs.

"Densho" means "to pass on to the next generation." In this quest, this website offers an archive of more than 668 oral histories presented in countless hours of video interviews on Japanese American incarceration during World War II. Materials also include approximately 12,000 historical photographs, documents, and newspapers. Visitors to this website should keep in mind that Densho is continually engaged in expanding its resources and adding more interviews, photographs, and documents, so be sure to check back periodically to discover new content!

Access to archival materials requires free registration. Once registered, users may select materials according to 32 topics, including immigration, community, religion and churches, education, race and racism, identity values, resistance, economic losses, redress and reparations, and reflections on the past.

Materials available without registration include lesson plans and information on "Causes of the Incarceration," "Civil Rights and Japanese American Incarceration," "Sites of Shame: Japanese American Detention Facilities," and "In the Shadow of My Country: A Japanese American Artist Remembers." The website also offers 90 multimedia materials providing historical context, a timeline, a glossary, and a list of related sources in print and online.

This website provides free access to a variety of visual materials and "seeks to illustrate the unique role of visual images in American history." Clio is an educational organization developing American history projects with appeal to a wide audience, including students, educators, and researchers. This site aims to not only provide access to a variety of visual historical materials, such as photographs, illustrations, and material objects (namely quilts), but also "to promote visual literacy by exploring the variety of ways that images enhance our understanding of the past and challenge us to hone our interpretive skills."

The website is organized into three main sections. The first, "Visualizing America," includes two collections of modules, titled "Picturing the Past: Illustrated Histories and the American Imagination, 1840–1900," and "Quilts as Visual History." A second section, ”Photography Exhibits," includes three photography collections: one focusing on the work of Frances Benjamin Johnston, another on the work of the Allen Sisters (Mary and Frances Allen), and the Peter Palmquist Gallery. A third section, "Creating History," examines the figure of Lowell Thomas, who became one of America's best known journalists, as well as the media version and reality of Lawrence of Arabia.

An additional section concerning women's history and lives in the 21st century and second half of the 20th century is planned for 2013.

A valuable website to students and researchers alike, it suffers only slightly from a lack of search capabilities.

The 190 works presented on this site—approximately 40,000 written pages and more than 3,000 illustrations—provide eyewitness accounts covering California history from the Gold Rush through the end of the 19th century. Most authors represented are white, educated, male Americans, including reporters detailing Gold Rush incidents and visitors from the 1880s attracted to a highly-publicized romantic vision of California life.

The narratives, in the form of diaries, descriptions, guidebooks, and subsequent reminiscences, portray encounters with those living in California as well as the impact of mining, ranching, and agriculture. Additional topics include urban development, the growth of cities, and California's unique place in American culture. A special presentation recounts early California history, and a discussion of the collection's strengths and weaknesses provides useful context for the first-person accounts.

Created in anticipation of the 50-year anniversary of the monumental Supreme Court decision, Brown v. Board of Education, this website covers four general areas. These include Supreme Court cases, busing and school integration, school integration in Ann Arbor (home of the University of Michigan), and recent resegregation trends in America. The site contains a case summary and the court's opinion for each of 34 landmark court cases, from Plessy v. Ferguson to Brown v. Board of Education of Topeka.

Brown includes transcripts of oral arguments, as well. Visitors can also read the oral histories of five members of the University of Michigan community who remember the Brown decision and its impact. There are more than 30 photographs of participants in the Brown case and other civil rights activists, as well as a collection of documents pertaining to desegregation in the Ann Arbor Public School District. A statistical section details the growing number of African Americans in Michigan and Ann Arbor schools from 1950 to 1960.

A work in progress, this site presents the southern Arizona school newspaper, Little Cowpuncher. Created by Anglo and Mexican American ranch children, from kindergarten through 8th grade, between 1932 and 1943 at five neighboring Arizona schools (Redington, Baboquivari, Sasco, San Fernando, and Sopori), the newspapers present the original and unedited stories, poems, and illustrations of students about their community and school life. The site includes a map that identifies the location of the five schools and users may select which newspaper they wish to examine by school and by year.

The newspapers include many stories about holiday celebrations, especially Halloween and Christmas. Also frequently featured are tales of rodeo activities and issues dedicated to graduating classmates. Other local events, such as an outbreak of chicken pox and droughts offer a unique perspective on the students' isolated rural lives.

Although the site is simply designed, middle and high school students and teachers will find that the newspapers present an opportunity to study pioneer Mexican and American ranch families and understand the bilingual and bicultural communities they created in Southern Arizona.

This collection of commercially produced Mexican American vernacular music is the largest of its kind, with more than 100,000 recordings. The music, originally published between 1905 and the 1990s, is primarily in Spanish. This website presents digitized versions of roughly 30,000 recordings. The music ranges widely in style and includes lyric songs, canciones, boleros, rancheras, sones, instrumental music, and the first recordings of norte and conjunto music, as well as politically motivated speeches and comedy skits.

A browseable list of subjects shows that love (unrequited love, adultery, regrets), war (Korean War, Mexican Revolution, World War I and II), and praise (of country, guitar, mother) are common themes in the collection. Unfortunately, the songs are available to the general public only in 50-second sound clips. Users interested in gaining full access to a select group of songs for research are encouraged to contact the website's administrators.

This collection of materials (more than 80 items) comes from rare books, pamphlets, journals, pulp magazines, newspapers, and original photographs. The illustrations reflect European interpretations of Native Americans, images of popular culture, literary and political observations, and artistic representations. The three main sections are "Portrayals of Native Americans," "The Nine Millionth Volume," and a timeline.

"Portrayals" is divided into four online galleries: Color Plate Books, Foreign Views, Mass Market Appeal, and Early Ethnography. The galleries incorporate the renowned works of George Catlin and Edward S. Curtis, and the lesser-known works of early 19th-century Russian artist-explorer Louis Choris. "Mass market" features 32 illustrations, including colorful images of western novel covers and portraits of southwestern Indians. "Early ethnography" contains a newspaper article about a Native American family, five photographs, and 15 illustrations of Indians at play and at war. "The Nine Millionth Volume" is devoted to James Otto Lewis's historic volume, The Aboriginal Port Folio, a series of hand-colored lithographic portraits of American Indian chiefs.
