No matter your interest, religious, political, environment, academic, left, right, or center, if you have interest in seeing things change (or stay the same), Better Together: Restoring the American Community by Robert Putnam and Lewis M. Feldstein, with Don Cohen (New York: Simon & Schuster, 2003) is a must read.
Better Together tells the stories of twelve different groups: from a community organization to a church, as well as a dance group and a web site, from a union to a branch library, a Fortune 500 corporation and a neighborhood group, to name a few. The stories hold in common the building up of community, of social capital. It is the best book of general interest that I have read in more than a year.
Putnam addresses a critical aspect of how we are brought together as citizens and neighbors. I cannot stress enough how highly I recommend this book.
