Here is a podcast I did with Sarah Long. Check it out. She also has a bunch of other great podcasts to check out as well:
Sarah talks with Dr. R. David Lankes, Associate Professor and Director of the Information Institute of Syracuse School of Information Studies at Syracuse University about the concept of participatory librarianship. They also discuss the mission of a librarian, learning as conversation, and the four major ways of facilitating knowledge and information.
