Nicola Iannello and Lorenzo Infantino have prepared a new Italian translation of Human Action based on Human Action‘s 1996 third edition. The new translation is considered to be an improvement over a previous Italian translation from 1959. You can find more information (in Italian) here and here.
This work adds to the growing number of Mises’s works that are available in Italian, including Bureaucracy, Theory and History, and Liberty and Property.
