Grothendieck's Éléments de géométrie algébrique, also known as EGA, was originally devised to consist of thirteen volumes (as stated in the introduction of the first volume), from which Grothendieck ended up writing only the first four ones, in the period 1960-1967. They were published inside Publications mathématiques de l’I.H.É.S. A second edition of EGA I was published by Springer in 1971, but then... that was it. There was no second edition of the other EGA volumes.
My question is: why did they not proceed with the second edition of the already existing EGA volumes?
Was Grothendieck himself opposed to a second edition? Why?
