The essay analyses the negotiations between Corrado Barbagallo and Guido Porzio on one side, Pietro Silva and Gioacchino Volpe on the other, on the basis of unpublished letters written between the beginning of 1915 and 1916 (whose, the most important are published in appendix). These negotiations concern the foundation and organisation of a new review that took the place of «Studi Storici», which seemed to disappear after his founder’s death at the end of 1914. It is clear how the «Nuova Rivista Storica», created in 1917, was strictly related to the historiographical movement known as economic-juridical.
