Innovation

	This book provides a number of case studies and coherent reasons why innovation is collaborative, and takes place at the intersection of social worlds.
Innovation and heterogeneous knowledge in managerial contact networks Simon Rodan	The idea of "structural holes" in its simplest form is a "water through the pipe" metaphor for networks. Someone who controls the flow between two parts of the network has power, the idea of a "broker." In this paper Rodan shows that there are other ways that information is flowing and that heterogeneity of knowledge is more important for innovation than structural holes.
	This is another book on the relational nature of creativity and innovations. Though it only occasionally mentions "social networks," one of its major points is that creativity needs to be thought of as a collaborative process and social networks are a way of talking about collaboration.
The Social Origin of Good Ideas Ronald Burt	This is another paper that discusses innovation as borrowing ideas from one social world to another.
Social Networks, the Tertius Iungens Orientation, and Involvement in Innovation David Obstfeld	This remarkable study reinforces the idea of innovation as social, but introduces the idea of Terius Iungens, "the third who joins," a person that brings together different social worlds and drives innovations.
