In 1473 the city of Utrecht had a real scoop. Here the first dated book appeared in the Northern Netherlands, printed with loose lead letters: the Historia scholastica by Petrus Comestor (ca. 1100-1179). This early print, a so-called incunable, came from the presses of the Utrecht book printers and publishers Nicolaes Ketelaer and Gerard de Leempt. The work testifies to the remarkable printers’ history of Utrecht, to which the University Library has devoted a digital exhibition of Utrecht incunables and a geographical interface.
