Investigative Exercise 1. Library 2.0

Understanding of library 2.0:
Library 2.0 is a term coined by Michael Casey on his blog. It is user-centered and interactive library service. It is not about searching, but finding; not about access, but sharing. For example, we can share our book list in the Goodreads with friends, and follow the facebook of the libraries to receive updated information.
