Part of the Library of Congress American Memory site, this online archive draws from two Library of Congress collections on the life of Abraham Lincoln, the 16th president of the United States. The Abraham Lincoln Papers in the Library's Manuscript Division contain over 20,000 items, over 2000 of which are contained on this site. Items include correspondence, speeches, and reports accumulated primarily during Lincoln's presidency (1860-1865). The documents are accompanied by annotated descriptions (roughly 150 words) composed by the Lincoln Studies Center at Knox College. The papers are in chronological order and are keyword searchable. The second collection highlighted in this exhibit is "We'll Sing to Abe Our Song," over 200 sheet music compositions that represent the popular music of the Civil War era. These pieces are drawn from the Alfred Whital Stern Collection in the Library's Rare Book and Special Collection division. The sheet music is searchable by title, composer, and subject. The site also offers links to other Library of Congress sources on Lincoln, including a photograph gallery of 16 images of the Lincoln family and other political figures of the Civil War era; over 50 Civil War maps; and a link to lesson plans for the entire American Memory Collection, including eight Civil War lesson plans appropriate for elementary and secondary students. This site is ideal for researching Lincoln's presidency and popular culture of the Civil War era.

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.

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.

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.

Four guided investigations designed to teach students how to read primary sources and construct historical narratives lie at the heart of this website. Topics are: the Spanish-American War, the Scopes Trial, Social Security, and Rosa Parks. Each topic includes a short introductory video, a timeline of events, a central question, and extension activities. For example, the Rosa Parks investigation poses the question: "Why did the boycott of Montgomery's buses succeed?"

After completing a simple login, students read annotated documents—including letters written by the boycott organizers, a speech by Martin Luther King, Jr. and an interview with a woman working in Montgomery—and answer guiding questions, and draw on their responses to answer the question. The website also includes a useful introduction to the idea of historical thinking.

More than 300 U.S. government publications from World War II have been digitized for this site, an ongoing project that plans to add another 200 documents.

Materials include pamphlets and books emphasizing home front issues, such as air raids, preservation, child labor, and victory farms. All materials are searchable by title, author, subject, and keyword. Browsing is also available.

A companion collection of photographs, the "Melvin C. Shaffer Collection," depicts the home front situation in Germany, North Africa, Italy, and Southern France from 1943 to 1945. Shaffer was a U.S. Army medical photographer assigned to document the medical history of the war through major campaigns. Shafer took the photographs on this site—totaling approximately 340—unofficially with the goal of recording the war's impact on civilians.

Created by the First United States Army Group and the Twelfth Army Group, this collection consists of 416 situation maps from World War II. The maps show the daily positions of Allied army units during the campaigns in Western Europe, from the D-Day invasion on June 6, 1944, through Allied occupation in July 26, 1945. There are also more than 100 reports from the campaigns.

Maps offer insight into daily activities, but also a broad view of movement over time. In addition, they highlight the incomplete nature of information available to commanders in the field during war time. Visitors can search the collection or browse the maps and reports by title, creator, subject, place, or date. The site also includes an interactive essay on the Battle of the Bulge. Visitors can select the desired zoom level and window size for viewing maps.

Drawn primarily from documents at the National Archives' National Personnel Records Center, this exhibit explores "the contributions of the thousands of Americans, both military and civilian, who served their country during World War II." Arranged into seven sections--"Prelude to War"; "New Roles"; "Women Who Served"; "The War in the Pacific"; "The War in Europe" "Science Pitches In"; and "The War is Over"--the site presents approximately 60 photographs, editorials, letters, and governmental reports, such as General Benjamin O. Davis's 1943 report concerning racial discrimination in the military. A 3,000-word background essay narrates the materials. Though lacking in depth and limited in size, the exhibit offers a selection of valuable and interesting materials regarding the war effort.
