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.

The images in this collection, focusing on the Americas, come from books printed or created in Europe between about 1492 and 1825. Images include woodcuts, copper engravings, and paintings. The database, still being compiled, currently contains 6,685 images and will eventually contain some 7,500 images. Image viewing software is available from the site.

The visitor can browse the entire archive or search by time period, geographical area, keyword, or subject, including indigenous peoples, flora and fauna, artifacts, industry, human activities, geography, maps, city views and plans, and portraits. Some images, such as Ptolemy's map of the world, may be familiar. Others are reproduced for the first time. Navigation requires some practice, but is worth the effort.

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. In between, visitors will find Eli Whitney's 1794 cotton gin patent, the 1862 Pacific Railway Act, and the 1896 Plessy vs. Ferguson ruling.

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.
