"This is the most important pre-reservation document that we have for the Comanche language.... Its translation will have a market ...in linguistics, anthropology, and history. It should be in every university research library."
—James A. Goss, Professor of Anthropology, Texas Tech University
"[García Rejón’s] Vocabulario del Idioma Comanche remains the most extensive nineteenth-century Comanche word list, and as such is extremely important for the study of the Comanche language, culture, and history. . . . Gelo's work will find extensive use among both specialists and other people interested in the Comanche and their language."
