Providing access to social science data for member colleges and universities, this website presents data that covers a range of sociological and political areas. Issues include census enumerations; urban and community studies; conflict, violence, and wars; economic behavior; legal systems; legislative bodies; mass political behavior and attitudes; and organizational behavior.

While much of the site emphasizes the late 20th century, data sets such as "Historical and Contemporary Electoral Processes" and "1790–1960 Censuses" will be useful for historical research. Searching is available according to a controlled vocabulary of names, subjects, and geographical terms. There are 10 special topic archives with data geared to health, education, aging, criminal justice, and substance abuse and mental health concerns. A "data use tutorial" and links to related sites may be useful.

This comprehensive set of Congressional documents covers the nation's founding through early Reconstruction. Materials are organized into four categories: Continental Congress and the Constitutional Convention; Statutes and Documents; Journals of Congress; and Debates of Congress. The site provides descriptions of 16 types of documents, including bills and resolutions, American State Papers, the U.S. Serial Set, Journals of the Continental Congress, the Congressional Globe, and the Congressional Record.

A presentation addresses the making of the Constitution that introduced an 1834 compilation of Congressional debates and proceedings and a timeline presents American history as seen in Congressional documents. Special attention is directed to Revolutionary diplomatic correspondence, Indian land cessions, the Louisiana Purchase, the Journal of the Congress of the Confederate States of America, 1861–1865, the impeachment of Andrew Johnson, and the electoral college.

More than 40 million pages from more than seven million tobacco industry documents are presented on this website. Documents were made public as a stipulation of the 1998 Master Settlement Agreement to settle multiple lawsuits. Index records, prepared by tobacco companies, can be searched by full-text.

Documents range from the 1930s to 2002, though most were created since the 1950s, and deal with industry concerns such as marketing, sales, advertising, research and development, manufacturing, and expansion of business to developing countries. There are 80 links to related sites and promises to include more documents in the future. This project offers an abundance of material for studying the history of smoking, advertising, and 20th-century American business practices.

The Bureau of Refugees, Freedmen, and Abandoned Lands, also known as the Freedmen's Bureau, was established by the War Department in 1865 to supervise all relief and education activities for refugees and freedmen after the Civil War. The Bureau was responsible for issuing rations, clothing, and medicine, and had custody of confiscated lands in the former Confederate states and other designated territories. This website contains an extensive collection of Freedmen's Bureau records and reports.

Included are more than 100 transcriptions of reports on murders, riots, and "outrages" (any criminal offense) that occurred in the former Confederate states from 1865 to 1868. There are also 30 links to records and indexes of labor contracts between freedmen and planters between 1865 and 1872; seven links to related sites; six links to marriage records of freedmen, 1861–1872; and more than 100 miscellaneous state record items concerning freedmen.

A cooperative effort, this online repository presents 100 milestone documents in American history. The first document is the Richard Henry Lee Resolution of June 7, 1776, proposing independence for the American colonies. The last is the Voting Rights Act of 1965.

Additional documents include the 1882 Chinese Exclusion Act, Keating-Owen Child Labor Act of 1916, and orders and addresses by several presidents, including Franklin Delano Roosevelt and Dwight D. Eisenhower. There is a full-page scan and transcription of each document. In addition to the chronological list of 100 documents, the site includes a "People's Vote." Of the 100 documents, Americans voted the Declaration of Independence number one, followed by the Constitution and the Bill of Rights.
