text: In the Justice Society stories from the 1940s (in All-Star Comics), the Justice Society was used more as a framing device for its members' solo adventures. The stories tended to have the following structure: the Justice Society meets to discuss some new menace, they split up to undertake individual missions that somehow connect to said menace, and finally regroup for the showdown with the main villain. In the 1940s, most comic books were anthologies, and All-Star Comics was in practice not a major deviation from that. By contrast, the Justice League worked together more closely in their stories, thereby having a stronger identity as a team.
  In another change from the Justice Society stories of the 1940s, Batman and Superman were regular members of the cast, not mere "honorary members" who made occasional cameos.
  Justice League of America (vol. 1) #21 (August 1963) featured the first crossover story in which the Justice League meets and teams up with the Justice Society of America. In doing so, DC Comics brought back a number of legacy characters such as Doctor Fate and the Black Canary. The issue was a hit with readers and such crossovers became a recurring event.
  Justice League of America (vol. 1) was published from 1960 to 1987.
