Have you heard of Second Life? Second Life is an online digital world that it is being created by its residents. Currently, there are more than 1.3 million residents (avatars) in Second Life (SL) who are going to lectures, attending classes, hanging out in dance clubs, meeting people, buying and selling goods, and making money. Access to SL is free, but a fee-based subscription is needed for some activities.
As SL attracted inhabitants, it also attracted librarians who have set up libraries and are offering library services to other residents of SL. You can read about some of your colleagues' activities at http://www.infoisland.org. It you skim down through the blog postings there, I think you'll be amazed at what is happening in SL.
Second Life is getting a lot of press coverage (including me being interviewed on local TV), so likely you can search any news source and find articles about it. Several well-known companies are creating offices in SL, including Talis (a library management system vendor), IBM, U.S. Centers for Disease Control, Coca-Cola, and Reuters.
Finally, one more tidbit. Yesterday there was a news conference in SL with a woman Anshe Chung who is now worth more than $1 million in SL based on the property she owns, etc. She is being heralded as the first virtual world millionaire. Amazing!
