Review of: David Billis (Editor), Hybrid Organizations and the Third Sector. Challenges for Practice, Theory and Policy, Palgrave Macmillan, London, 2010.

When this book was published in 2010, the terms hybrid and hybridization did not have a common and widespread definition in the scientific community of the social sciences, although several were proposed (Powell 1987; Brandsen, van de Donk, and Putters 2005; Evers 2005; Brandsen, Karré, and Helderman 2009). The authors of Hybrid Organizations and the Third Sector recognize that there are many possible area of hybridization among organizations belonging to the three main sectors of society: public, private (for profit), and the third sector; editor and contributing author David Billis affirms that one of the goals of this book is to go beyond a vague description of the hybridization phenomena as “the blurring of the boundaries of the three sectors” by offering the following definition: a hybrid organization is an organization that “possesses significant characteristics of more than one sector”. The main focus of the book, however, is the “role of hybrid organizations in the third sector”.
