The editions of Dante’s works represent as many responses as there are questions raised by their peculiar manuscript tradition. This chapter discusses the methodological procedures of the main editorial enterprises related to Dante’s vernacular works and the results achieved by these enterprises. It also addresses the tradition of the Latin works. It discusses the geographical dissemination of manuscripts and the value of local traditions insofar as they help us find a way out of the complicated tradition of the Commedia and of the Rime. The chapter also investigates the ways in which the tradition bears marks of authorship, focusing on such problems as the debated existence in manuscripts of a ‘song book’ planned by Dante himself or on the possible authorial chapter division of the Vita Nova. Dante’s philology is always an ‘author-oriented’ philology showing at its best to what extent philology and hermeneutics can reinforce one another.
