Social Capital: A Theory of Social Structure and Action: 19 (Structural Analysis in the Social Sciences, Series Number 19)

Social Capital explains the importance of using social connections and social relations in achieving goals. Social capital, or resources accessed through such connections and relations, is critical (along with human capital, or what a person or organization actually possesses) in achieving goals for individuals, social groups, organizations, and communities. The book introduces a theory that forcefully argues and shows why "it is who you know," as well as "what you know" that makes a difference in life and society.
