I'm reading the first volume of Scharlau's Grothendieck biography (eagerly anticipating the other two/three volumes) and the Grothendieck-Serre correspondence as part of a historical-philosophical side project. I find myself regularly digging up papers of his, and sometimes this can be difficult, especially when the reference he makes to the paper in one of the letters is a bit vague.
My question: are you aware of any (at least fairly) comprehensive Grothendieck bibliographies? i.e. could you point me in the direction of a nice listing of some large fraction of his work, preferably organized in some coherent way or other?
There is an extensive biblioraphy in The Grothendieck Festschrift, Volume I, Birkhäuser (December 22, 2006)
