Last year I suggested to Aragno, an Italian publisher, that a new edition of "Calcolo geometrico secondo l'Ausdehnungslehre di H. Grassmann preceduto dalle operazioni della logica deduttiva" [Peano 1888] by Giuseppe Peano (1858–1932) be published. He accepted my proposal [Peano 2010]. This book had never been previously reprinted until 2000, when an English translation by Lloyd C. Kannenberg appeared [Peano 2000]. In 2002, Clara SilviaRoero published aCDof the OperaOmnia of Peano [Roero 2002] containing a copy of the original edition.
