The best public domain footage sources for documentary makers

A curated list of public domain and CC0 collections for documentaries: film, photographs, maps and audio, with what each is strong on and how to check an item's status.

Public domain material is the foundation of most independent documentaries. It's free, it's safe to monetise, and there's far more of it than most creators realise. Here are the collections worth knowing.

Film and video

• Prelinger Archives (on the Internet Archive). Thousands of industrial, educational and amateur films from the 1920s to the 1980s. Explicitly free to use.
• US National Archives. Government films, newsreels and military footage; US federal works are public domain.
• NASA. Launches, missions, animations and imagery, nearly all public domain.
• NOAA and USGS. Weather, oceans, geology, satellite footage.
• Internet Archive's "Feature Films" and "Newsreels" collections. Check each item; many are public domain, some are not.

Photographs

• Library of Congress Prints & Photographs. Search with "no known restrictions" as a filter.
• Wikimedia Commons. Filter by licence; millions of PD and CC0 images.
• The Met, Rijksmuseum, Smithsonian Open Access. Museum collections released as CC0, superb for art and object history.
• Unsplash and Pexels. Modern photos under permissive licences, for establishing shots.

Maps

• David Rumsey Map Collection. Historical maps, many freely usable with attribution.
• Library of Congress Geography & Map Division. Public domain historical maps.
• Natural Earth. Free vector map data for building your own maps.

For animated maps with correct historical borders, generated maps are often faster; Glisse builds them for the year you name.

Audio

• Freesound (CC0 filter). Sound effects and room tone.
• Musopen. Public domain classical recordings.
• Library of Congress National Jukebox. Early recordings.

Checking status, quickly

1. Prefer collections with an explicit statement ("no known restrictions", CC0, US government work).
2. Read the item's own licence field, then check it against the collection's policy.
3. For anything with a person's likeness or a trademark, remember that copyright isn't the only right involved.
4. Keep a log of source and licence for every asset.

The faster route

Doing this by hand is the 8–12 hours per film that most documentary budgets underestimate. Glisse's licence-aware footage search covers these collections, matches assets to your narration line by line, rejects unsafe licences at search time, and keeps the provenance for each asset, so the film is safe to publish and monetise.

FAQ

Is all old footage public domain?

No. Age alone doesn't make a work public domain; it depends on when and where it was made and whether rights were renewed. Check each item.

Can I monetise videos made from public domain footage?

Yes. Public domain material can be used commercially, including in monetised YouTube videos.

Does Glisse use public domain footage?

Yes, as a first source, along with other provenance-clear archive collections, with the licence recorded for each asset.
