ABSTRACT
In this introductory article, the authors argue that major changes in the way we conceive of time and temporality that are taking place today justify the increase of studies, both theoretical and empirical, on shift s in cultural constructions of time. In this context, the authors present four articles written by members of the network Iberconceptos, where a number of time experiences in the Ibero-American world (Latin America, Spain, and Portugal) during the eighteenth and nineteenth centuries are discussed from a conceptual perspective.
