The Webester's book
Here is the descritpion of the Webster's book that I mentioned at the class. He explains a variety of scholars who deal with post-industrial or informational society. He also implies public library as public sphere, by borrowing Habermas' theoy of communicative action. I hope that you folks find something useful through this book.
