This bibliography presents a list of titles that help the reader to understand the Latin American history. The sources for population history, tributary counts, parish registers, etc. are abundant in Spanish America. Even though the first century after the conquest continues to attract most of the research in population history, a recent shift has begun to favour the late colonial period. From tax assessments and civil or ecclesiastical censuses the spatial and social distribution of the population and its increase or decrease have been studied. The study of the hacienda as a productive unit in the creation of new forms of exploitation of the soil and of labour is a relatively recent phenomenon in Mexico. The transformation of large tracts of Indian land into private estates owned by Spaniards gave rise to new forms of soil exploitation based on new systems of labour, which in turn created a new pattern of relations between workers and landowners.
