The Descripción de las provincias del virreinato del Perú, printed a few provinces a year in an almanac

A survey of ninety-six provinces of a South American viceroyalty, issued serially in the annual almanac of the chief cosmographer of Peru and arranged by bishopric. Each entry gives bounds in leagues, climate, crops and yields, mines, rivers and parishes, and sometimes a population figure. Its closing paragraph says how it was made and why it took so long: the corregidores were slow, and many returns came back too thin to use.
