A total vision for the book

In this interview Henri-Jean Martin gives his definition of written heritage: books which have influenced society in the past. Director of the Municipal Library in Lyon from 1962 to 1970, he evokes the enrichment of its patrimony that he has led and challenges the conceptual difference between public librarianship and heritage collections. In the field of research, he defines the librarian's role and that of the researcher and raises questions around the place of the history of the book.
