Tra Roma e Berlino. Luigi De Gregori, il GW e altre tracce della “repubblica degli incunabolisti”

Incunabulists, although often divided by fierce controversy, formed a bibliographical “republic”, exchanging information and verifications among themselves and collaborating towards increasingly precise knowledge of fifteenth-century printing. Several interesting examples are found in the papers of Luigi De Gregori (1874-1947), director of the Biblioteca Casanatense and later inspector general of libraries, about the planning of the IGI and the Italian collaboration with GW. The preparatory materials for his studies on Torquemada’s Meditationes and on the Subiaco types have been preserved, as have an unpublished translation of Haebler and a copy of the first volume of IGI “marked” by Tommaso Accurti.
