I just found this great site to view video presentations from a bunch of different types of organizations. Mediasite.com is
[A] growing library of expert presentations and lectures … It’s a search tool that brings together public presentations and lectures created with Sonic Foundry’s Mediasite system. You have free, on-demand access to a steadily growing database of online technical content created by hundreds of experts.
I did a search for “library” and got 59 results - pretty nifty.
