Nahuatl is the Latin American indigenous language having the largest number of colonial documents. As with other colonial documents, the study of these manuscripts requires mastery of the language as well as the relevant historical and philological sources. The emergence of digital repositories in Mexico, the United States, France, and other countries has made hundreds of digital images available to scholars who would not have had access to these sources otherwise. Digital repositories also contain additional tools such as morphological parsers and dictionaries. These allow users to upload new images, transcriptions, and translations, turning digital archives into veritable platforms for scholarly exchange. The irruption of digital repositories promises to effect substantial changes in the field of Nahuatl studies.
