The National Archives and Records Administration (NARA) has approximately 1899 historic, public domain films in its vaults. The Internet Archive has some of these available for viewing, but otherwise, they are not available on the web. In an effort to encourage NARA to make these available online, Public.Resource.org posted 20 of these films from a NARA DVD (available only from Amazon) on YouTube. The idea is to demonstrate how interested the public would be in these films if readily available. There are some historic moments, including the crash of the Hindenburg.
