Who Shall Survive? A new approach to the problem of human interrelations

Washington, DC: Nervous and Mental Disease Publishing Co, 1934. First edition. Original black cloth, blocked in green; xvi, 437 pp., one ad leaf. 3 inch crack in rear endpaper, but a very good copy. Illustrations in black, red, blue, and green. There is an inscription on the front endpaper indicating its use by the War Office Selection Board in 1942. The Board was a scheme by British Army psychiatrists to discover and develop officer candidates, and Moreno's sociometrics were influential in Eric Trist and Wilfred Bion's experiment of Regimental Nomination, where units were encouraged to nominate candidates.
Linton C. Freeman identified four defining properties of social network analysis: (1) It involves the intuition that links among social actors are important. (2) It is based on the collection and analysis of data that record social relations that link actors. (3) It draws heavily on graphic imagery to reveal and display the patterning of those links. And (4) it develops mathematical and computational models to describe and explain those patterns.
He wrote "Until the 1930s, however, no one had used all four properties at the same time.... Modern social network analysis was introduced by a psychiatrist, Jacob L. Moreno, and a psychologist, Helen Jennings. They conducted elaborate research, first among the inmates of a prison, later in a reform school for girls. Moreno and Jennings named their approach sociometry." A chapter on psychological geography anticipates the work of the Lettrist International.

"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." Garrison-Morton-Norman 7700.
