The Clements Library hosted an exhibit of materials related to Early American printing, including the “Doctrina Breve … copuestra par el Reveredissimo S. do fray Jua Cumarraga,” printed in Mexico in 1544. Considered the earliest surviving complete book printed in the Americas, it was a catechism printed in Mexico City for the first archbishop of Mexico, Juan de Zumárraga. One of the first books printed in South America, Tercero Cathecismo y exposicion de la Doctrina Christina (Lima, 1585)—a catechism printed for missionary use in Spanish and Quechua—was also featured at the exhibit.
