The sixth book in the series "Sem Título" (Untitled) is an essay by Ruth Rosengarten on the links between photography and the archive in contemporary art, plotting a personal trajectory through the works of the Berardo Collection by linking artists such as Marcel Duchamp, Anselm Kiefer, Hiroshi Sugimoto and Bernd and Hilla Becher. Beside the text, now published in English, the book includes colour reproductions of the works selected.
