 In the early 1980s, Tor Books collected sixteen of the stories (including "Virgin Planet"), with forewords and intertextual commentary by Sandra Miesel, into three volumes under the general title "The Psychotechnic League".The name was an homage to Anderson's better known future history series about the Polesotechnic League, a future interstellar version of the historical Hanseatic League.The third volume also included a modified version of the timeline from "Startling Stories".
