The outstanding mathematician Federigo Enriques (1871-1946) acted as scientific adviser to the publisher Zanichelli in Bologna, where he was professor of projective geometry at the University. This paper reconstructs his activities from 1894 to 1938, when he was forced to leave the publishing house due to the race laws. Enriques exerted a strong influence on the publisher in the choice of authors (from Castelnuovo to Amaldi and Fermi) and the structure of its book series; he also gave equal consideration to highly specialised texts and those by teachers at high school and university. Together with Eugenio Rignano, he founded the journal Scientia in the pursuit of a necessary synthesis of science, humanities and didactics, which was his hallmark both as a scholar and a chief editor. The development of Federigo Enriques’ deep editorial involvement is documented with reference to book series and titles, relations with authors and sales figures, ending with a look at percentages and ratios between students and teaching staff in Italian schools from unification onwards.
