In the fall of 1938 Poggioli was hired as a visiting lecturer in Romance language and literatures at Smith College, Northampton, Massachusetts, where he gave a course in Dante.
Poggioli's most ambitious project during this period was his founding editorship, with Italian writer Luigi Berti[REF] who was based in Florence, of the Italian language literary periodical Inventario (1946-1963) to which Poggioli contributed numerous articles and translations.
