Presidents from George Washington to Barack Obama have delivered 214 State of the Union addresses, some delivered orally and many more only written. This website makes the full text of all addresses available and fully searchable, and has done some innovative work text-mining these speeches to examine "changes in the language of the State of the Union address over the past 200 years."

A good place to begin is the website's Essay section, which gives a brief history of the State of the Union address, and describes some of the project's most interesting findings. The website's most prominent feature is a series of graphical representations of the most frequently used words in each address, which allows users to compare those words to those of any other speech.

Another tool allows users to compare the usage of two words in all addresses delivered. Comparing "war" and "peace," for example, reveals that these words have been used in 206 of the addresses, and that the word "war" alone has been used more than 2,600 times, compared to 1,821 usages for "peace."

Established by Ronald Reagan, the Reagan Foundation preserves Presidential history and is "dedicated to the promotion of individual liberty, economic opportunity, global democracy, and national pride." Its online presence provides both primary and secondary sources on the life and presidency of Reagan.

Visitors can follow a timeline of Reagan's life in Life and Times, and read five short essays (800–1,000 words) on his domestic, foreign, and economic polices, Mikhail Gorbachev, and "Reagan the Man" in The Presidency. Search or browse Reagan's speeches, with both transcripts and video recordings and search or browse quotes drawn from his speaking in Reagan Quotes and Speeches. The entries of his White House Diary from 1981–1989 may also be browsed, and a separate subsection on Nancy Reagan provides a timeline of her life and brief essays on her relationship with Ronald Reagan and her political causes.

The Reagan Foundation's Archives make only a fraction of their holdings available online. However, visitors can access fast facts on Reagan and his presidency; browse a selection of photos of the President and the First Lady, organized by topic; or search or browse (by month) the Public Papers of President Ronald W. Reagan, which includes statements, speeches, and papers released by the Office of the Press from 1981–1989.

The Archives' For Educators section includes several document-based lesson plans, as well as curriculum based on current museum exhibits.

Useful for educators looking for both introductory material to Reagan and his presidency and more specific primary sources.

This website serves as an introduction to the Abraham Lincoln Presidential Library and Museum in Springfield, IL.

In addition to logistical information on visiting the library and museum (including floor plans, photographs, tips on planning school visits, exhibit information, and archival collection descriptions especially useful for researchers), the website also presents a substantial amount of digital material on Lincoln's life and times and Illinois history more generally.

New users may want to begin with an extensive timeline documenting major events in Lincoln's life.

The website also includes a Boys in Blue database of many Illinois soldiers who fought for the Union during the Civil War, as well as an oral history project documenting the lives of Illinois citizens from all walks of life. Current topics include war veterans and agriculture, with plans to include hundreds more interviews on statecraft, war and terror, family memories, and African American history.

Although he was not the first president to be filmed for motion pictures, Theodore Roosevelt was the first to have his life chronicled through extensive use of the then-new medium. This site, part of the Library of Congress American Memory Collection, offers 104 films depicting events in Roosevelt's life, from the Spanish-American War in 1898 to his death in 1919. The Theodore Roosevelt Association Collection provided 87 of the films and the remainder came from the Library of Congress Paper Print Collection of the Motion Picture, Broadcasting, and Recording Sound Division.

The films include scenes of Roosevelt with world figures, politicians, monarchs, friends, and family members. The films are not accompanied by lengthy explanatory text; they include only a brief, 10–15 word caption describing their contents.

Special presentations on this site include: a film chronology offering a timeline with 150–200 word outlines of each period in Roosevelt's life covered in film; a text-based timeline from Roosevelt's birth in 1858 to his death in 1919; "T.R. on Film," a roughly 750-word scholarly essay; four sound recordings, with transcriptions, Roosevelt made for Edison company in 1912 in which he stated his progressive political views; and an image of "Theodore Roosevelt: The Picture Man," a 2,000-word article from a 1910 The Moving Picture World magazine.

See also the 250-word description of the collection, a 15-work selected bibliography on Theodore Roosevelt and motion pictures, and links to four related websites. A "Learn More About It" section includes 12 other Library of Congress special presentations and related collection sites for those who wish to learn more about Roosevelt and his times. This site is a good resource for learning about Theodore Roosevelt and the United States around the turn of the 20th century.

This site documents the American presidential elections from 1860 to 1912. For each election, the site provides a detailed, 3,000-word overview that places the election within political and cultural context, and discusses the major issues relevant to the election. The producers have also included an essay on the practice of campaigning (4,500 words): how it has changed over the centuries, how those changes have resulted in an increased democratization of the political process, and how the press has shaped the process. In addition, the site exhibits about 90 political cartoons (from Harpweek, Vanity Fair, and Puck, among others) from elections, and provides biographies for each of the candidates. Also included for each election are "Events" sections that discuss major events before, during, and after each election period.

Teachers should be aware that some materials contain racial epithets. Notwithstanding the relatively few primary sources, this site is an excellent introduction to the 1860 to 1912 elections.

An engaging exhibit geared especially to schoolchildren, this site provides images, texts, and activities to explore the history and operation of the American presidency. Organized into four sections, the exhibit displays more than 375 images of documents, paintings, photographs, buttons, posters, paraphernalia, and objects along with short texts (50–200 words in length) explaining their significance. The Foundations pertains to the prehistory of the presidency, how the Framers defined responsibilities of the office, and the basic work that the office requires. The Campaign Trail covers the election process. Life and Death in the White House looks at the domestic world of the president, life after leaving office, and assassinations. Communicating the Presidency deals with the press, the entertainment industry, and advertising.

Most impressive are the many suggested activities, lesson plans, and games designed for children of varying ages. A Teacher's Manual contains five lesson plans each for grades 4–6, 7–9, and 10–12. In addition, there are activities for younger children, including analyzing letters between children and five presidents and creating a new official seal. Provides a timeline, bibliography of 88 titles arranged according to age group and exhibit section, and annotated list of 46 links to other sites. Very useful for classroom history and civics courses.
