This exhibit assembles a wide assortment of materials from the 1920s, items loosely related to the prosperity of the Coolidge years and the rise of a mass consumer economy. The collection includes more than 400 documents, images, and audio and video clips on subjects ranging from automobiles, consumer goods, department stores, families, Motion Picture News, and the National Negro Business League, to politics.

An introductory essay provides valuable background information on the Coolidge administration with additional insight on the social and cultural context of the era. An alphabetized guide to people, organizations, and topics includes definitions and brief descriptions. This sort of material has not been widely available, and this collection is extremely valuable as a resource on the development of mass consumption.

These documents, exhibits, photographs, and essays tell the history of 26 prominent 20th-century scientists, physicians, and experts in biomedical research and public health.

The Social Security program and the institutional history of the Social Security Administration (SSA) and its contribution to the welfare of the American public are presented on this site. It contains a vast collection of oral histories, audio recordings, and primary documents of the SSA. The audio and video clip section includes radio debates on the merits of the Social Security program taped during 1935, Lyndon B.

These four collections of data and documents address Federal Indian policy in the late 19th century. The first set includes eight annual reports of the Commissioner of Indian Affairs from the 1870s, along with appendices and a map. The second set, Allotment Data, traces the Federal "reform" policy of dividing Indian lands into small tracts for individuals—a significant amount of which went to whites—from the 1870s to the 1910s. This set includes transcriptions of five acts of Congress, tables, and an essay analyzing the data.

The third set includes 111 documents on the little-known Rogue River War of 1855 in Oregon, the reservations set up for Indian survivors, and the allotment of one of these reservations, the Siletz, in 1894. The fourth set provides the California section of an ethnographic compilation from 1952.

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.
