Codev2 and The Wealth of Networks

Both books are available for download at no charge, but can be purchased.

I recommend Lawerence Lessig's "Codev2" as it has some great ideas relating to creative commons and copyleft.

With Yochai Benkler's book, The Wealth of Networks: How Social Production Transforms Markets and Freedom, I skipped through a few of the chapters that were less relevant to me.
