New Whole Earth Reference Library · Knowledge & Learning
Description: A collection of over 6,000 “ephemeral films” — advertising, educational, industrial, and government films from the 20th century — hosted on the Internet Archive and free to download and reuse.
Why it matters: These films document everyday American life, domestic expectations, labor, and consumer culture in ways that formal history rarely captures. They’re unfiltered primary sources from mid-century America.
Strengths: Massive, freely downloadable, and largely in the public domain — usable without restriction for research, education, or creative projects.
Limitations: Content reflects its era; expect dated social norms, advertising assumptions, and outright propaganda in some titles.

Cost: Free
Note: Invaluable for researchers, educators, and filmmakers who want primary visual sources from 20th-century American life.
