In this podcast, George and Joan use this blog post from In the Library with the Lead Pipe as a jumping off point for a far reaching conversation about what libraries really are all about, and why they should continue to exist. There's lots of great food for thought to chew on.
Among the things they discuss: the Digital Public Library of America, an initiative you can read more about here (and about which Joan, for one, has some very strong opinions!). George also mentions his work with the IFLA/OCLC Fellows. You can read more about that program here.
Oh, and here's a link to their podcast on sustainability, which they make reference to in this podcast.
