Who shall survive? A new approach to the problem of human interrelations.

Moreno founded psychodrama, and pioneered group psychotherapy. Apart from its psychiatric and sociological significance, this work contained some of the earliest graphic depictions of social networks— data visualization methods later applied to numerous other disciplines. These images were later called sociograms. For a second edition published in Beacon, New York in 1953 Moreno revised the title to Who shall survive? foundations of sociometry, group psychotherapy and sociodrama.  Digital facsimile of the 1953 edition from asgpp.org at this link.
