Consists of samples of a larger set of material excerpted by the collector from his original field recordings. Conversations, elicited word lists with Spanish equivalents, and texts in three Guatemalan languages. Recorded in Guatemala in 1969.

The Reina Papers contain the professional papers of cultural anthropologist Ruben E. Reina (1924-2016). Reina is an emeritus professor of anthropology and curator of ethnology who taught at the University of Pennsylvania and worked at that institution's University Museum of Archeology and Anthropology from 1957-1990. Broadly interested in modern and historical cultures of Central America, South America, and Spain, he is most widely known for his contributions to the study of the culture and peoples of Guatemala. The collection contains Reina's correspondence, administrative records, teaching materials, research notes, subject files, and written works from his career. Of particular interest are the notes from his fieldwork in Guatemala, Argentina, Spain, and Puerto Rico. A further significant component of the papers is the records of the Hispanic-Latin American Research Project. Reina served as director of the long-term project (1967-1988), during which a team of scholars compiled thousands of pages of Spanish colonial materials from the Archivo General de Indias (AGI) in Seville, Spain and Archivos General de Centro America (AGCA) in Guatemala. The Reina Papers serve as a vital storehouse of this important historical material.
