Here's the playlist I made to compile all of the GLAM-Wiki session videos at Wikimania: http://www.youtube.com/playlist?list=PL0D29D4F1A5C44E8F&feature=plcp
Sorry if someone else has done this, but I didn't notice one and I needed an easier link for the GLAM-Wiki social queues. : )
I'll be updating as the videos come in. I know that they're not all up yet.
