Social capital is a form of mobilization whose core is not on individuals or in forms of economic production, but in the complex networks of solidarity and trust. The book Comunicação e política: capital social, reconhecimento e deliberação pública (that translated to English means Communication and politics: social capital, recognition and public deliberation) is a collection of articles written by researchers in communication about this subject, organized by Ângela Marques and Heloiza Matos.
