Copyright on the web is a hugely complex and controversial area, and YouTube is right on the front lines. I'm not going to go into detail about the ins and outs of it here (and I'm not an expert by any means!), but where YouTube is concerned it's been interesting to see the two approaches being played out in changes to the site. On the one hand you have the copyright holders that are cracking down hard on any infringement (or perceived infringement) - there was a huge fuss last year when YouTube went through and removed the audio from thousands of fan videos, essentially rendering them pointless. Now when you upload videos it will run automatic checks on the audio and may block the video if it discovers copyright infringement, depending on whether the copyright holder demands this. (Of course the usual response by the person who made the video is to try another, less restrictive, site, like Photobucket or Bam Vid Vault, or will just share via a filesharing site like Sendspace or Mediafire, so it doesn't actually stop the videos from being made and distributed!) But not everyone is taking this approach - many such videos now have pop-up adverts along the bottom which tell you the song that is used and link you to iTunes to buy a copy - thus using the illegitimate use to generate sales. The other way in which copyright holders are working with YouTube is to put content up themselves, figuring that if they make things (or parts of things) freely available it might reduce the amount of stuff put up by other people (and YouTube allows some corporate users to put up longer clips than the standard 10 minute limit). The Monty Python channel is a great example of this - they explicitly say so (and check out the trailer for the Not the Messiah film if you're there - my Dad's in it!).
Anyway, having said I wasn't going to say much about YouTube and copyright I seem to have done so! If anyone wants to read more about copyright and the web though I can recommend the writings of Cory Doctorow and Lawrence Lessig in particular - their two recent books are both in the Staff Library and also available as free PDF downloads, so take a look.
OK. Enough about copyright. Back to the original point of this Thing.
Much like the rest of the web, YouTube has enormous potential for libraries and educational institutions, as well as students and researchers, as long as you are able to apply those critical faculties and sort through the haystack in order to find the needles you want. YouTubeEDU is YouTube's equivalent of iTunesU for podcasts, and just like iTunesU there's some really amazing stuff there when you browse through. However I want to highlight an excellent library-specific example, again from the Library of Congress. They use their YouTube channel not only to put up information about the library and videos of their events, but also for video footage from their archives, making these clips more widely available in just the same way as they do photgraphs via the Flickr Commons. Again they also put up a lot of this kind of material on their own site, but YouTube makes them more visible on the web and more easily findable by people that might not otherwise go to their site, as well as presenting material in a more accessible and user-friendly way.
Before I go, a quick note about subscribing to YouTube channels. At first glance, YouTube only seems to let you do this via your log-in to the site, but you can do so via RSS - fellow 23er CybrarianBeta has blogged about how to do this if anyone is like me and would prefer to subscribe in Google Reader.
