FedFlix, hosted by the Internet Archive, is a collection of nearly 2000 films produced by the US government during the 20th Century. The topics of these films range from presidential speeches to agricultural practices to public health and safety. Some films are instructional in nature, for example there is a film for police officers on how to arrest someone. Other films are more informative in nature and some films are flat-out propaganda films.
All of the FedFlix films are in the public domain so feel free to reuse and remix them as you desire. The films can be downloaded or viewed online. Films can also be embedded into your blog or website.
