Mendinueta wrote an extensive "Memoria Sobre el Nuevo Reino de Granada" (1803). He took issue with the negative portrayal of the colony given by one of his predecessor, Archbishop Antonio Caballero y Góngora. The work, divided into four parts (ecclesiastical affairs, administration, finances and the military), is an important account of the colony at the beginning of the nineteenth century, just before the war of independence. The work has not been published in English, and only recently in Spanish (, 2003).
