From the Preface: There are three volumes. The first one contains a curriculum vitae a «Brève
Analyse des Travaux» and a Iist of publications including books and seminars. In addition the
volume contains all papers of H. Cartan on analytic functions published before 1939. The other
papers on analytic functions e.g. those on Stein manifolds and coherent sheaves make up the
second volume. The third volume contains with a few exceptions all further papers of H.
Cartan among them is a reproduction of exposés 2 to 11 of his 1954 55 Seminar on
Eilenberg-MacLane algebras. Each volume is arranged in chronological order. The reader should
be aware that these volumes do not fully reflect H. Cartan's work a large part of which is
also contained in his fifteen ENS-Seminars (1948-1964) and in his book Homological Algebra with
S. Eilenberg... Still we trust that mathematicians throughout the world will welcome the
availability of the Oeuvres of a mathematician whose writing and teaching has had such an
influence on our generation.
