Abstract
This paper attempts to show the wealth of information kept in the archive of Mexico’s first Indigenist Coordination Center, founded in 1951 in San Cristobal de las Casas, Chiapas. It describes the implementation of a preservation project and highlights the difficulties found during its application, its stated goals and their degree of fulfillment, the criteria and methodology adopted, as well as the final results obtained, which have made available to all those interested an extraordinary amount of information about the history of the Tzeltal-Tzotzil region of Chiapas over the past halfcentury.
