This digital archive features a number of recordings and texts in the indigenous languages of Latin America.  Materials are available in Mixteco, Mam, Nahuatl, Otomi, Triqui, Zapoteco, and many other indigenous languages.  These materials give information about the cultures of these indigenous groups.  Original works of literature in indigenous languages are also published on this site.  AILLA works to preserve written forms of these languages, but it also collects grammars, dictionaries, ethnographies, and research notes that can be used as teaching materials.   Most of the archive is free and available to the public.
