These papers reflect the professional and personal life of Frederica de Laguna. The collection contains correspondence, field notes, writings, newspaper clippings, writings by others, subject files, sound recordings, photographs, and maps. A significant portion of the collection consists of de Laguna's correspondence with family, friends, colleagues, and students, as well as her informants from the field. Her correspondence covers a wide range of subjects such as family, health, preparations for field work, her publications and projects, the Northwest Coast, her opinions on the state of anthropology, and politics. The field notes in the collection mainly represent de Laguna and her assistants' work in the Northern Tlingit region of Alaska from 1949 to 1954. In addition, the collection contains materials related to her work in the St. Lawrence River Valley in Ontario in 1947 and Catherine McClellan's field journal for her research in Aishihik, Yukon Territory in 1968. Most of the audio reels in the collection are field recordings made by de Laguna, McClellan, and Marie-Françoise Guédon of vocabulary and songs and speeches at potlatches and other ceremonies from 1952 to 1969. Tlingit and several Athabaskan languages including Atna, Tutochone, Upper Tanana, and Tanacross are represented in the recordings. Also in the collection are copies of John R. Swanton's Tlingit recordings and Hiroko Hara Sue's recordings among the Hare Indians. Additional materials related to de Laguna's research on the Northwest Coast include her notes on clans and tribes in Series VI: Subject Files and her notes on Tlingit vocabulary and Yakutat names specimens in Series X: Card Files. Drafts and notes for Voyage to Greenland, Travels Among the Dena, and The Tlingit Indians can be found in the collection as well as her drawings for her dissertation and materials related to her work for the Handbook of North American Indians and other publications. There is little material related to Under Mount Saint Elias except for correspondence, photocopies and negatives of plates, and grant applications for the monograph. Of special interest among de Laguna's writings is a photocopy of her historical fiction novel, The Thousand March. Other materials of special interest are copies of her talks, including her AAA presidential address, and the dissertation of Regna Darnell, a former student of de Laguna's. In addition, materials on the history of anthropology are in the collection, most of which can found with her teaching materials. Although the bulk of the collection documents de Laguna's professional years, the collection also contains newspaper articles and letters regarding her exceptional performance as a student at Bryn Mawr College and her undergraduate and graduate report cards. Only a few photographs of de Laguna can be found in the collection along with photographs of her 1929 and 1979 trips to Greenland.
