The 20th-century portion is in development. "The Price of Civilization" makes available 14 posters and more than 6,500 pages of federal documents—primarily Treasury Department reports—on the development of the current tax system during the Great Depression and World War II. "Presidential Tax Returns" includes returns of recent presidents and Vice President Cheney. "Taxing Federalism" features nine Federalist Papers, and "Image Gallery" offers 15 political cartoons from the turn of the century to 1947, many by Washington Star cartoonist Clifford Berryman.

These more than 350 recently declassified documents from archives of former Warsaw Pact countries and the U.S. reveal previously hidden aspects of Cold War military strategy. The project offers documents and accompanying analyses in six categories: Warsaw Pact records; Warsaw Pact war plans; NATO records (U.S. and British); national perspectives (Bulgaria, Romania, Hungary, China, and Poland); crises (Berlin and Libya); and intelligence.

The website also provides 13 oral history interviews with former officials, including two Eisenhower administration officers involved with NATO planning and nuclear weapons policies. Documents reveal a 1964 Warsaw Pact war plan for using nuclear weapons in a preemptive strike against NATO forces and a 1965 Hungarian Army exercise detailing the targeted destruction of Western cities, including Vienna, Munich, Verona, and Vicenza. A 30-page survey article assesses the new history written since the release of recent documents.

More than 55,000 photographs taken by staff photographers of the Chicago Daily News during the first decades of the 20th century are available on this website. Roughly 20 percent of the photos were published in the paper. The Chicago Daily News was an afternoon paper, sold at a cost of one cent for many years, with stories that tried to appeal to the city's large working-class audience.

The website provides subject access to the photographs, which include street scenes, buildings, prominent people, labor violence, political campaigns and conventions, criminals, ethnic groups, workers, children, actors, and disasters. Many photographs of athletes and political leaders are also featured. While most of the images were taken in Chicago and nearby areas, some were taken elsewhere, including at presidential inaugurations. The images provide a glimpse into varied aspects of urban life and document the use of photography by the press during early 20th century.
