There is a feature on YouTube.com where you can join a "group", related to a specific subject, and then add any videos from their entire website that "fit the bill" to the group's list. This way you have a one-stop list of all the videos that relate to a given topic. I started a group for vintage Golden Age bodybuilding clips. You can find it at:http://www.youtube.com/group/goldenage
I just did a quick search of their site and threw some clips in there that seemed appropriate. If you join the group you can add to the list any videos that you find (or post yourself) on YouTube.com that relate to Golden Age bodybuilding. All members of the group will then be able to find them very easily. They'll even automatically e-mail you when a new video is added to the list.
