Books that define why and how the world is changing

If I had to choose three books that define how the world is changing, I mention:



- The Long Tail: Why the Future of Business is Selling Less of More - Chris Anderson




- Wikinomics: How Mass Collaboration Changes Everything - Don Tapscott, Anthony D. Williams








- The World Is Flat 3.0: A Brief History of the Twenty-first Century - Thomas L. Friedman






Because I think those three books define why and how the society, the economy and the companies are changing nowadays.
