Books for bringing the next level of democracy to organizations

I am just finishing the book "Presence" by Peter Senge, C. Otto Scharmer, Joseph Jaworski and Betty Sue Flowers. If you can cut through some of the early "hug-a-tree" stuff, there is a gold mine of information to think about as it relates to the demonstrated failures or so many of our institutions and the possibility that exists for making them better by looking at the Whole rather than the parts. This work is a logical extension of the work of Dee Hock in "Birth of the Chaordic Age" and the work of Margaret Wheatley in "Leadership and the New Science."
If you are in a leadership role today and thinking about the future of your organization, I highly recommend these books for your reading list.
