In February 1971 to July 1973, President Richard Nixon secretly began recording phone conversations and meetings, compiling thousands of hours of tape. Created in 2007 by a Texas A&M University history professor, this website intends to provide "the most complete digitized Nixon tape collection in existence."

At present, only a fraction of the recordings are available. Visitors may listen to MP3 versions of over 500 conversations organized by primary conversation participant; 29 conversations organized by topic themes; and more than 2,000 hours of conversations organized by the date of their release to the general public.

Though the site promises that all recordings will eventually be accompanied by full transcripts, accompanying material is spotty. Some recordings are accompanied by corresponding entries from the presidential daily diary, some by general outlines of the recording's topics, and a handful by full transcripts. The recordings vary in quality, from fully audible to inaudibly faint or noise-obscured.

The website is not searchable (the search engine on the home page searches the web at large). As it stands, it may be useful to educators as a casual introduction to the recordings for students, but locating specific content (to accompany lesson plans or complement events being taught in class) would require significant time.

This collection offers 32 transcripts and a dozen audio excerpts, all recently declassified, of conversations between former U.S. President Richard Nixon and the former president of Mexico, Luis Echeverria Alvarez. The audio files come close to 170 hours of conversation between the two leaders. Both men were involved in secret operations at the time of the conversations (Nixon was involved in the Cambodia bombings, while Echeverria was fighting a "Dirty War" against political opponents in Mexico), although only Nixon knew the conversations were being recorded. The two presidents often mused about geopolitics and only occasionally discussed the most-frequently debated issues between the two nations (such as drugs or trade). Although the tapes are available in other archives, the focus of the site makes it useful in exploring the relationship between Nixon and Echeverria.

This site explores the not-so-obvious relationship between Richard Nixon's interest in sports, his politics, and his reputation as a public figure. Professional historian Nicholas Sarantakes designed the site as the electronic version of a forthcoming book. A timeline from 1969 to 1974 provides descriptions (5-20 words) on sports-related and other important events in Nixon's presidency. Watergate events, for instance, are intertwined with Nixon's interest in relocating the San Diego Padres to Washington, D.C. In 16 photographs and six cartoons, Nixon is shown as spectator and participant at sporting events. He is quoted talking about sports on 13 different occasions. The site refers visitors to two articles by Sarnatakes on the topic of Nixon and sports. The site may be interesting to cultural historians in general and useful for research in sports history and the history of the presidency in particular.

President Thomas Jefferson worked on designing his estate, Monticello, throughout much of his adult life, drawing heavily on classical architecture as well as the French architecture he became acquainted with during his time in Paris in the 1780s. This website presents an interactive map of Monticello, at its height a 5,000 acre plantation—its buildings, fields, orchards, and slave quarters—providing a window into Jefferson's domestic life.

Visitors can click on one of more than 25 locations on the Plantation, and see a short explanation of that place's function, as well as a small selection of current and historical photographs and documents pertaining to that location, including some of Jefferson's original building plans. Visitors can then virtually move inside Monticello itself through a 3-D tour of Jefferson's home, accompanied by text highlighting the social function of each room.

Also offered are virtual tours of the house, highlighting domestic life at Monticello and Jefferson's relationship with farming and gardening. Each of these tours is accompanied by a useful video introducing these topics and providing other background information about Jefferson's life and work.

These 12,000 items (72,000 digital images) allow the visitor to explore James Madison's life, the Revolution, or the Early Republic. Materials include his father's letters, Madison's correspondence, personal notes, drafts of letters and legislation, and legal and financial documents. Material covers the period from 1723 to 1836.

Page images of correspondence can be browsed by title, name, or correspondence series or they can be searched by keyword or phrase appearing in the bibliographic records (descriptive information) of the collection. Additionally, the full text of correspondence for which transcriptions are available can also be searched by keyword or phrase. A timeline covers the period from 1751 to 1836 and is useful for placing the events of Madison's life in historical context. Three essays are available, including one on Madison's life and papers and one on Madison at the Federal Constitutional Convention.

A continuing project of high school history and science classes, this site presents thousands of political cartoons concerning the presidency of Franklin D. Roosevelt.

Selected from the collection at the Hyde Park Presidential Library of Basil O'Conner—Roosevelt's New York City law partner—the materials are arranged into eight subject categories and often include brief background essays and questions designed to prompt further inquiries. Periods currently emphasized include 1932, "The Road to Pennsylvania Avenue"; 1937, "The Supreme Court"; and 1943, "The War Years."

Well-conceived and executed, the site also gives the texts of Roosevelt's inaugural addresses and a page of teacher resources and suggested projects.

This wealth of historical materials, in a variety of formats, addresses Abraham Lincoln's years in Illinois (1831–1860) and Illinois history during the same period. The website provides more than 2,300 transcriptions of documents, including correspondence, speeches, treaties, and other official papers. In addition, there are 295 images of Lincoln, his family, friends, associates, and contemporaries, as well as Illinois towns, homes, and businesses, and 63 recordings of songs.

Materials are organized into eight thematic sections: African American Experience and American Racial Attitudes; Economic Development and Labor; Frontier Settlement; Law and Society; Native American Relations; Politics; Religion and Culture; and Women's Experience and Gender Roles. Each theme includes a background essay, relevant documents and images, video discussions by prominent historians, and narrated slide shows. "Lincoln's Biography" divides his life into eight segments with a summary and biographical text by scholars, as well as a bibliography.

This website features approximately 20,000 documents relating to President Abraham Lincoln's life and career. All of the materials are available as page images and about half have been transcribed. Resources include correspondence, reports, pamphlets, and newspaper clippings. While the documents date from 1833 to 1897, most material was written between 1850 and 1865, including drafts of the Emancipation Proclamation and Lincoln's second inaugural address. A chronological index offers names of correspondents and document titles.

Special presentations on the Emancipation Proclamation and the Lincoln assassination provide introductions, timelines, and 24 images of related documents and engravings. Additional resources include 16 photographs of the Lincolns and key political and military figures of Lincoln's presidency. This is an excellent resource for researching Lincoln's presidency and American politics prior to and during the Civil War.

This is a companion site to a 1999 National Museum of American History exhibit of Fred J. Maroon's photographs taken during the last four years of Richard M. Nixon's presidency. Maroon, a freelance photographer known for his images of Washington's monuments and landscapes, recorded Nixon's presidency from 1970, through the 1972 reelection campaign and the Watergate controversy, to the impeachment hearings and Nixon's resignation in 1974. The site is divided into four chronologically-arranged sections. The "White House" contains photographs taken in 1970 and 1971 while Maroon worked on a behind-the-scenes book about the White House Staff; "Reelection" records images of Nixon's 1972 reelection campaign; "Hearings" offers photographs of the White House staff during the Watergate crisis and impeachment hearings; and "Final Days" captures the events leading up to Nixon's resignation in 1974. The site offers more than 25 images selected from the museum exhibit as well as a timeline of the Nixon presidency from 1968 to 1974 and a 200-word biography of Maroon. For those interested in Watergate and the Nixon administration, this is a good site.
