These full-text first-person narratives present the voices of more than 2,000 people from northeast Ohio discussing issues significant to the state and the nation. These oral histories, collected since 1974, focus on a range of topics such as ethnic culture, including African American, Greek, Irish, Italian, Jewish, Puerto Rican, Romanian, and Russian, and industry, such as steel, pottery, brick, coal, and railroads.

Others discuss labor relations, including women in labor unions, wars (World War II, Vietnam, Gulf War), college life (including the shootings by National Guard troops at Kent State in 1970), the Holocaust, and religion. Subject access is available through more than 200 topics listed alphabetically.

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.

Published annually by the State Department, Foreign Relations of the United States (FRUS) is the official record of major declassified U.S. foreign policy decisions and diplomatic activity. Material, including transcripts of tape recordings, comes from Presidential libraries and executive departments and agencies. Digitized material does not reflect the full range of the published volumes. Documents included have been selected for their ability to illuminate "policy formulation and major aspects and repercussions of its execution."

The first website covers the years from 1861 to 1960.

Decisions involve a wide range of topics, including international arbitration and the protection of migratory birds. Visitors may search volumes individually or the whole set by keyword, subject, and date.

The second website offers materials from 1945–1972. Materials come from the Truman, Eisenhower, Kennedy, Johnson, and Nixon administrations. Additional volumes will be added on the Nixon and Ford administrations.
