Addl. KW Subjects:
This subseries of the Mexico/Central America/South America series consists of highly miscellaneous, unsorted notes which were found scattered throughout Harrington's papers. Most of the material deals with Mexico and Central America, although there are data relating to South America and possibly to his study of placenames and province names. The notes were recorded during various periods of time as evidenced by the different types of paper used; most are undated. There are references to Aztec, Tarahumara, Tarascan, Cochimi, Cora, Chontal, and Tojulabal. Castulo Ucan, an informant with whom Harrington worked in New York, is mentioned. Perhaps of greatest interest is a four-page list of Zapotec words, consisting of numbers and miscellaneous vocabulary, which was elicited from a Mr. Harvey in February 1923.
