The heart of this collection about President Lyndon Baines Johnson is a group of 77 oral history interviews (up to 200 pages each) with members of Johnson's administration, Congressional colleagues, journalists, civil rights leaders, and a historian. The website provides 14 audio files, including telephone conversations, State of the Union addresses, Johnson's speech to Congress following the Kennedy assassination, and an excerpt of his television address announcing his decision not to run for a second term.

Also available are transcripts of 25 speeches; 50 "days of" diary entries; and the 99 National Security Action memoranda issued during Johnson's presidency relaying foreign policy directives and initiating actions. There are 150 photographs and one campaign advertisement. Biographical information is furnished in two chronologies. An exhibit from the Johnson museum provides an essay about events in Johnson's lifetime.

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.

Another notable feature is the 37 oral history interviews conducted by SSA in the late 1960s and early 1970s. Additional oral history collections are featured, providing information about the 1977 creation of Health Care Financing Administration and policy issues involving the Medicare and Social Security programs.

The full-text versions of more than 40 works by Jack London (1876–1916), a prominent early 20th-century writer who was also involved in the socialist movement, are available here. Materials include famous fiction, such as The Call of the Wild (1903), and lesser-known works, such as War of the Classes (1905), a collection of speeches London delivered on behalf of socialism. The website includes 20 novels, 19 short story collections, two collections of essays, three plays, and six additional published nonfiction works. The website is keyword searchable. In addition to providing the writings of Jack London, there is plenty of biographical and historical information about London and his times. Outside resources are suggested, divided into those suitable for students and those for teachers. Combining London's original works with other contextual materials provided by the site could be valuable for studying early 20th-century American literature and journalism and its relation to radical political and social currents of the time.

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.

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.

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.

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.

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.

Each year since 1972, CQ Press has published a book of 100 significant documents in U.S. history accompanied by detailed annotations.

The documents are grouped by year and by topic. Topics include the economy, defense, the environment, health care, international affairs, and life in America. A "Favorite Documents" feature allows users to mark and collect documents of interest, and a "CiteNow!" feature provides citations on demand. Though the depth of documents on any one topic is minimal, this website provides an overview of important events in a given year as well as U.S. perception of and response to topics over time.
