It seems that Grothendieck's familly has given permission for the distribution of his unpublished works, so I hope it is ok to ask this.
Is there any way to obtain a copy (online or not) of "La longue Marche à travers la théorie de Galois"?
Note: I am aware that sections 26 to 37 and section 49 are avaible online at the Grothendieck Circle.
Note: a very informative article by Leila Schneps on this particular work can be found here: Grothendieck’s "Long March through Galois theory".
