The aim of this study is to reconsider the nature of the relationship between the two editions of Claudio Merulo’s Ricercari d’intavolatura d’organo, libro primo (Venice, 1567; ibid., 1605). On the basis of a careful bibliographic analysis it is possibile to highlight the probable derivation of the posthumous reprint produced by Angelo Gardano in 1605 from the original edition published by the same Merulo in 1567 and, more generally, various aspects related to the materiality of the editorial work concerning the publishing of a music book at the time.
