The video below explores the libraries implemented in Second Life by different institutions, both public and academic. This video and others I've posted are by HVX Silverstar one of the few individuals in SL creating video and recording the evolution of Second Life. You may view more of her videos on YouTube.com.
Someone recently asked me how I keep up with the new technologies. One way is by subscribing to individuals who post on YouTube. People such as HVX Silverstar. When I find a librarian, professional or academic I admire, I click on the yellow subscribe button next to the video player. I select google email as my delivery method and from that point on I receive links to their latest videos.
