In the 20th century, the decree of 11 March 1923 changed its composition and its purpose. The compilation of the Vocabolario, hitherto the duty of the Crusca, was removed from it and passed to a private society of scholars; the Crusca was entrusted with the compilation of philological texts. In 1955, however, Bruno Migliorini and others began discussion of the return of the work of preparing the Vocabolario to the Crusca.[18]
