The ACRL Virtual World Interest Group sponsored a book discussion on July 22, 2012 in the virtual world of Second Life.
Title: Beyond the Blogosphere: Information and Its Children
The authors, Aaron Barlow and Robert Leston came into Second Life (as avatars) to discuss the book and answer questions. Topics discussed included the digital revolution and changes in information that impact libraries and librarians.
ACRL VWIG Convener, Valerie Hill, captured some of the event on machinima (video shot in a virtual environment) which can be viewed here:
