This is a great site that has been mentioned here before. It is an entirely legitimate project, done in cooperation with the filmmakers. When there are commercially available sources for the films, it does provide connections to them (which I, for one, have taken advantage of). For documentaries like this, the filmmakers want to have them seen, and a site like that provides access and information for people (like us) who would have an interest in them.
