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."

This website boasts a growing collection of more than 38,000 photographs, lithographs, letters, cards, poems and other texts centering around Indiana history from the early 19th century to the present. The collection is especially strong in African American history in Indiana, with browseable collections on Madam C.J. Walker (1867–1919), a nationally renowned businesswoman and philanthropist, Flanner House, the first agency in Indianapolis devoted to meeting the social service needs of African Americans, and the Indianapolis Recorder, the longest continually operated African American newspaper in Indiana.

In addition to that of Madam C.J. Walker, there are collections of roughly 100 images each related to other notable Hoosiers. The website also contains a collection of more than 1,000 items related to President Lincoln, including portraits and busts of the president, as well as documents surrounding the trial of the Lincoln assassination conspirators. Other notable collections include one devoted to military history, several collections of images and portraits of Native Americans from the mid-19th century, and close to 200 historical maps of Indiana. All content is keyword searchable.

This website presents nine "Digital Collections" containing more than 10,000 primary sources on many aspects of Wyoming's 19th and 20th-century history.

The Palen Collection contains more than 200 programs, news clippings, brochures, and photographs surrounding Cheyenne's Frontier Days and rodeos from around the state.

Those interested in the history of studio photography will be particularly interested in the close to 3,000 photographs from a studio in Laramie, WY, in the Ludvig Svenson collection.

The Richard Throssel collection contains more than 550 early 20th-century photographs of Native American life and culture.

Other highlights include a small collection of journals, manuscripts, photographs, and articles surrounding the life of writer Owen Wister and his travels in the West; close to 500 photographs and more than 4,000 documents relating to ranch life in Wyoming; and a collection of photographs of Roscoe Turner and the early history of aviation.

The website also presents two collections of research projects conducted by University of Wyoming undergraduates, as well as a collection entitled Digital Herbaria, which contains high-resolution photographs and data for 6,014 vascular plant specimens found in the Grand Teton National Park.

Teachers will be especially interested in the website's Teacher Resources section, which includes links to a substantial number of lesson plans emphasizing critical analysis of primary sources.

The largest public archive of Ulysses S. Grant correspondence to date, the collection includes letters, research notes, artifacts, photographs, and memorabilia. Topics cover Grant's childhood, military career, and experiences in the Civil War through his presidency and post-White House years.

The bulk of the collection is made up of 31 full-text searchable, digitized volumes of The Papers of Ulysses S. Grant. Edited by John Y. Simon, these volumes comprise thousands of letters spanning from 1837, just before Grant left for the Military Academy at West Point, to his death in 1885. The volumes also contain photographs, a chronology of the correspondence, and annotations.

In addition to the extensive Papers, the collection provides a sampling of digitized material from the U.S. Grant Association, including 14 multi-page compilations and 11 political cartoons from sources such as Harper's Weekly and Puck. Items include detailed, linked metadata to assist in tracking source provenance and connecting to related sources. Additionally, all items are keyword searchable and can be browsed by format, date, or title.

On September 11, 1857, roughly 120 members of the Baker-Fancher wagon train—bound westward towards California from Arkansas—were killed in Mountain Meadows, UT, by the local Mormon militia and their Indian allies. Once known as a welcoming oasis for wagon trains, subsequent reporting in newspapers and the proceeds of an official government investigation into this event transformed Mountain Meadows into a site of shame. Debates emerged over the causes of the massacre, with some arguing that the members of the Baker-Fancher party had abused local Mormon populations, and others arguing that the killings were largely unprovoked.

This website presents an archive of primary sources surrounding this event. Currently, the website presents 40 newspaper accounts written between 1857 and 1859 from newspapers in Arkansas, Chicago, California, and Nebraska. Eventually, the archive will also include government investigation reports; early Mountain Meadows Massacre histories in Western Americana; Apostate and Anti-Mormon publications; and fiction, drama, and film. Rather than re-hash the facts surrounding the massacre, the website focuses on the creation of documentation about the massacre, presenting primary sources that allow users to explore representations of the event from multiple perspectives.
