Hello, Anybody can recommend where to find old documentaries to watch online, outside youtube? I am looking for old films about zoos, like 'Zoo2000' or German 'Zoos der Welt - Welt der Zoos' and old documentaries e.g. from Alan Root about Africa. They are not sold, can hardly make profit, and image quality is usually poor by modern standards. However they are of value for documentary and nostalgic purposes. For example to compare how animal exhibits improved during the last decades. Anybody can advise how to see them?
