This is one of the richest collections of anti-slavery and Civil War materials in the world. Reverend Samuel J. May, an American abolitionist, donated his collection of anti-slavery materials to the Cornell Library in 1870. Following May's lead, other abolitionists in the U.S. and Great Britain contributed materials. The collection now consists of more than 10,000 pamphlets, leaflets, broadsides, local anti-slavery society newsletters, sermons, essays, and arguments for and against slavery. Materials date from 1704 to 1942 and cover slavery in the United States and the West Indies, the slave trade, and emancipation. More than 300,000 pages are available for full-text searching. Accompanying the documents are eight links to other collections.

Over 6,000 documents from more than 150 FBI files, declassified due to Freedom of Information Act requests, are available here. No contextual information is available concerning individual documents, although file headnotes identify the person or event profiled in short one-sentence to one-paragraph descriptions. Documents, some of which are available in PDF format, have been organized into twenty categories—ranging from Popular Culture to Foreign Counterintelligence, and the Gangster Era to Unexplained Phenomena (such as UFOs and animal mutilations). Although the collection covers a variety of topics, many documents have been heavily censored and are barely legible. Cases from the first half of the 20th century include: the Sacco-Vanzetti case in the 1920s; the 1932 Bonus March; the Black Legion of the 1930s; the Young Communist League, 1939–41; and the Daily Worker in the late 1940s and 1950s. More recent cases include the murder of three civil rights workers in Mississippi in 1964; SNCC, beginning in 1964; the Ku Klux Klan in 1964 and 1965; a Black Panther Party chapter beginning in 1969; the Watergate break-in of 1972; the white hate group Posse Comitas in 1973; the Weather Underground in the 1970s; and the Gay Activists Alliance of the 1970s.

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.

This website contains 129 pamphlets, documents, and newsletters produced by or relevant to radical movements. Groups represented by one to 30 documents include the American Indian Movement; Asian Americans; the Black Panthers; the Hollywood Ten; the Ku Klux Klan, the IWW, and the Students for a Democratic Society. Additional situations covered include the Rosenberg case, Sacco and Vanzetti, and the Scottsboro Boys. Additional topics include birth control and the events at Wounded Knee. This is a small but useful resource on radicalism, political movements, and rhetoric.

The collection includes more than 30,000 items relating to African American life in Ohio between 1850 and 1920, including personal papers, association records, a plantation account book, ex-slave narratives, legal records, pamphlets, and speeches. More than 15,000 articles from 11 Ohio newspapers and the African Methodist Episcopal Church Review, perhaps the oldest African American periodical, are included. Also provides more than 300 photographs of local community leaders, buildings, ex-slaves, and African American members of the military and police. Materials represent themes such as slavery, abolition, the Underground Railroad, African Americans in politics and government, and religion. Items include an extensive collection of correspondence by George A. Myers, an African American businessman and politician, as well as prominent political speeches.

Bringing together a wide range of material on the public communications of American presidents, as well as election data and statistical information on presidency, this website presents the public messages, statements, speeches, and news conference remarks of presidents from Herbert Hoover to George W. Bush. Materials can be browsed or searched by month and year. Visitors can also view transcripts of all inaugural addresses and State of the Union messages, convention speeches of presidential candidates from 1960 to 2004, and all the presidential debates.

The site offers major party platforms from 1840 to 2004 and transcripts of various events from the 2001 presidential transition. Transcripts from the "Presidential Candidates Debates" from the 1960 through the 2004 election are presented. A media archive contains various audio and video clips from the late 19th century to the present. A map shows electoral votes and popular vote totals and percentages by state from 1828 to 2004.

Thomas Jefferson outlined three motivating factors in his instructions to Lewis and Clark: a search for navigable rivers to span the continent; a quest for Edenic beauty and riches; and the competitive desire to acquire a continental empire. These 180 documents and artifacts interpret 19th-century westward exploration from this perspective. The range of materials is striking. In addition to maps, plans, and charts, the site offers images (sketches, watercolors, etchings, and engravings), texts (letters, diaries, speeches, newspapers, and books), and tools (surveying and medical instruments, cooking utensils, armaments). The exhibit opens with an examination of the "imperial mentality" common to Virginia's aristocratic class in the late 18th century and then focuses on the Lewis and Clark journey. It ends with the subsequent expeditions of Zebulon Pike, Stephen H. Long, Charles Wilkes, John Charles Fremont, and the mid-19th century transcontinental railroad plan that supplanted the search for a water route.

More than 100 published materials on legal aspects of slavery are available on this website. These include 8,700 pages of court decisions and arguments, reports, proceedings, journals, and a letter. Most of the pamphlets and books pertain to American cases in the 19th century. Additional documents address the slave trade, slave codes, the Fugitive Slave Law, and slave insurrections as well as presenting courtroom proceedings from famous trials such as the 18th-century Somerset v. Stewart case in England, the Amistad case, the Denmark Vesey conspiracy trial, and trials of noted abolitionists John Brown and William Lloyd Garrison. A special presentation discusses the slave code in the District of Columbia. Searchable by keyword, subject, author, and title, this site is valuable for studying legal history, African American history, and 19th-century American history.

Created to honor Studs Terkel, the noted oral historian, radio host, and Pulitzer Prize-winning author, this website makes available more than 400 audio clips of interviews Terkel conducted over 50 years. The seven galleries explore a variety of subjects, including organized labor, the 1929 stock market crash, New Deal programs, World War II, Hiroshima, folk music, race relations, politics, and urban life in Chicago.

The interviews present well-known figures as well as ordinary voices, such as people traveling by train to the March on Washington in 1963. Complementing these interviews is a 55-minute video interview with Terkel in which he emphasizes the importance of accurate knowledge about the past. An educational section addresses the use of oral history in the classroom. This well-designed site is valuable for studying the Great Depression, World War II, race relations, and labor issues.

Created by a nonprofit group interested in "open debate on federal, state, and international tax policy," this site furnishes an eclectic range of primary and secondary resources on the history of American taxation.

"Presidential Tax Returns" includes returns of recent presidents and Vice President Cheney. "Taxing Federalism" features nine Federalist Papers, and "Image Gallery" offers 15 political cartoons from the turn of the century to 1947, many by Washington Star cartoonist Clifford Berryman. The site also offers a bibliography and four sound clips of federal officials discussing tax policy.
