Social networks are all around us and concern various aspects of our lives. Undoubtedly, describing their power and scope in personal, interpersonal, organizational, and social levels requires special treatment. Charles Kadushin attempts a concise and comprehensible presentation of the theory of social networks, drawing mainly from sociopsychological or sociological theories. Avoiding declarative speech, he explains in a particularly accessible way both the structural properties of social networks and their dynamics, thus making this textbook one of the most suitable teaching tools that fills a gap in the existing literature.
