Using contemporary newspaper accounts, eyewitness testimonies, photographs, maps, drawings, and later texts, this site presents "narrative threads" linking the events leading up to John Brown's raid in 1859 on the Harper's Ferry arsenal to "the latent history of life in the two Shenandoah Valley towns of Staunton, Virginia, and Chambersburg, Pennsylvania." Includes 13 issues of newspapers from the towns; five eyewitness accounts ranging from 2,500 to 9,800 words in length; 30 images of the Brown family members and conspirators; approximately 25 additional photos, published drawings, and maps; a brief listing of Brown's day-to-day movements during the latter half of 1859; and short biographical entries of up to 500 words on each conspirator. This site, parts of which are presently under construction, will be of special interest to teachers who want to use contemporary images and written accounts in their classes on Brown and abolitionism, and for those looking to investigate local history perspectives on events of national importance.

This site considers which "of the more than 110 million items in the Library of Congress" are considered "treasures." The items in the exhibit are organized into the categories of Memory (History), Reason (Philosophy), and Imagination (Fine Arts), as was the personal library of Thomas Jefferson, which became the core of the Library of Congress.

The exhibit, which offers images of original documents as well as explanatory essays, contains such items as Jefferson's "original rough draft" of the Declaration of Independence, Jedediah Hotchkiss's Civil War maps, Edison's Kinetoscopic record of a sneeze, and Earl Warren's handwritten notes concerning the Miranda decision.

Scholarship on the Cold War has been written primarily by Westerners with little access to sources in Soviet archives. This extensive collection seeks to remedy this gap in Cold War historiography by presenting sources from the former Communist bloc. Thousands of documents in the diplomatic history of the Cold War are currently available, stretching in time from the 1945–46 Soviet occupation of northern Iran through the late 1990s.

The annotated sources are divided into 50 collections and by geographic region. Collections cover a wide range of topics, including specific events (1954 Geneva Conference on Indochina, 1956 Hungarian Revolution, 1980–81 Polish Crisis) and broader topics stretching over longer periods of time (Economic Cold War, Nuclear Non-Proliferation, The Cold War in Africa). Collections vary widely in size, between three and several hundred documents, and include primarily official documents and communication—meeting minutes, memoranda, transcribed conversations between leaders, reports, and several personal letters and diary entries.
