      note          = "Despite the essential role of common salt in preindustrial
                       societies, our knowledge about its  production on the
                       Iberian Peninsula is currently deficient. The dominant
                       historiographical  tendency presumes solar evaporation
                       production during the Iron Age. This paper puts forward a
                       series of cartographies on productivity potential in an
                       area of great salt-mining tradition: the Mountainous
                       Territory of Historic Celtiberia. The productivity
                       potential has been obtained based on the multi-criteria
                       analysis and calculations of several variables that
                       influence the production process –geology, insolation,
                       precipitation index, temperature, incline and altitude–
                       during the Iron Age. The analysis of cartographies has
                       shown considerable differences in the productivity
                       potential of the area of study due to differences in
                       climatological conditions.",
