The municipal archive contains records from the Archivo Civil del Municipio de Tzintzuntzan. From the separate archival registries on births, marriages, and deaths (including cause of death), Prof. George M. Foster has hand copied individual records for persons associated with the village of Tzintzuntzan (and rarely, other hamlets within the municipio) for the period covering 1930 (the beginning of the municipio) to the early 1990s. Fosters records (on 5 x 8 sheets) exist in paper format only, with the original at the University of California at Berkeley and a backup copy with Kemper at SMU in Dallas. Information from these records has been entered into the master fichero for persons censused in Tzintzuntzan in one of the ethnographic censuses (i.e., 1945, 1960, 1970, 1980, 1990, and 2000).
