This wealth of data presents National Election Studies surveys of the American electorate conducted in presidential and congressional election years from 1948 to 2006. Large files of raw data can be downloaded. In addition, The ANES Guide to Public Opinion and Electoral Behavior is available and is readily accessible.

Composed of more than 100 tables and graphs, the guide traces nine key variables in the makeup and opinions of the electorate. These include: social and religious characteristics; partisanship and evaluation of political parties; ideological self-identification; public opinion on public policy issues; support for the political system; political involvement and partisanship; evaluation of presidential candidates; evaluation of congressional candidates; and vote choice. This website also provides pilot studies on recent surveying issues, such as measuring exposure to television advertisements, and a 5,000-item bibliography.

The 150 cartoons presented here were drawn between 1929 and 2000 by three-time Pulitzer Prize-winning political cartoonist Herblock (Herbert Block). Cartoons comment on major events and public issues.

The website also presents an essay by Block on "the cartoon as an opinion medium"; a biographical essay; and 15 caricatures of the cartoonist by well-known colleagues. Cartoons are organized according to 13 chronological sections, with an additional segment devoted to presidents. Brief annotations provide historical context for each image.

A tribute site by the Washington Post, Herblock's longtime employer, offers additional cartoons and essays by Block.

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.

Highlights of Coca-Cola television advertisements from the Library of Congress Motion Picture archives are exhibited on this site, with 50 commercials, broadcast outtakes, and experimental footage.

There are five examples of stop-motion advertisements from the mid-1950s, 18 experiments with color and lighting for television ads from 1964, and well-known commercials, such as the "Hilltop" commercial featuring the song "I'd Like to Buy the World a Coke" (1971). Additional resources include the "Mean Joe Greene" commercial (1979); the first "Polar Bear" commercial (1993); the "Snowflake" commercial (1999); and "First Experience," an international commercial filmed in Morocco (1999).

The site also includes a bibliography and links to finding aids for other television commercials at the Library of Congress. While this site is relatively small, it provides a good resource for studying the history of post-World War II consumer culture in terms of content and technique.

Designed to help users better understand the evolution and complexity of medicinal marketing in the 20th century, this website provides more than 600 health-related advertisements printed in newspapers and magazines from 1910 to 1960. Ads are organized into six categories: Household Products; Over-the-Counter Drugs; Personal and Oral Hygiene; Vitamins and Tonics, Food, Nutrition and Diet Aids; Institutional and Pharmaceutical; and Cigarettes. Over-the-Counter Drugs; Personal and Oral Hygiene; Vitamins and Tonics, Food, Nutrition and Diet Aids provide the largest number of advertisements; the Cigarette category offers only one.

Supplementary materials, such as internal reports from marketing companies, American Medical Association reports and editorials, Federal Trade Commission archival records, transcripts of 1930s radio commercials, and medical journal articles, focus on the production and influence of health-related advertisements. A bibliography provides 80 further reading suggestions. The project highlights materials for case studies on Fleischmann's Yeast, Listerine, and Scott Tissue.

These resources come from a privately held collection of 20th-century American ephemeral films, produced for specific purposes and not intended for long-term survival. The website contains nearly 2,000 high-quality digital video files documenting various aspects of 20th-century American culture, society, leisure, history, industry, technology, and landscape. It includes films produced between 1927 and 1987 by and for U.S. corporations, nonprofit organizations, trade associations, community and interest groups, and educational institutions. More than 80 films address Cold War issues.

Films depict ordinary people in normal daily activities such as working, dishwashing, driving, and learning proper behavior, in addition to treating such subjects as education, health, immigration, nuclear energy, social issues, and religion. The site contains an index of 403 categories. This is an important source for studying business history, advertising, cinema studies, the Cold War, and 20th-century American cultural history.

These audio files, abstracts, transcriptions of oral arguments, and written opinions cover more than 3,300 Supreme Court cases.

Users can access cases through keyword searches or a list of thirteen broad categories, such as civil rights, due process, first amendment, judicial power, privacy, and unions.

Cases include Roe v. Wade (abortion), Gideon v. Wainwright (right to counsel), Plessy v. Ferguson (segregation), Grutter v. Bollinger (affirmative action), and Bush v. Gore (election results). Biographies are provided for all Supreme Court justices and "The Pending Docket" provides briefs and additional materials on upcoming cases. The website also includes links to written opinions since 1893 and podcasts featuring discussions of cases starting in 1793.
