La corrispondenza con Alberto Ferrero della Marmora nell’Archivio di Stato di Biella

This paper reconstructs the epistolary exchange between Giovanni Spano and Alberto Ferrero della Marmora through the correspondence preserved in the University Library of Cagliari and the State Archive of Biella. For the unpublished letters housed in the Piedmontese archives, a twofold research tool is proposed: firstly, the archival record containing a summary and an extrinsic description for each documentary unit; secondly, the edition of the 14 missives sent by the canon to the general from July 1861 to May 18, 1863, the date of Alberto Ferrero della Marmora’s death.
