The Edwin Tappan Adney papers contain materials created or collected by Adney relating to First Nations' linguistics, ethnology, heraldry, and other related topics of interest.

The Frank G. Speck Papers consist of field notes, correspondence, lecture notes, printed sources, photographs, drawings, ephemera, and manuscripts of published and unpublished works.

The Wendell S. Hadlock Collection of Edwin Tappan Adney Research contains some of Adney’s research about First Nations that was removed from his home, by Hadlock, after his death. Hadlock and Adney appear to have been friends or colleagues, with shared research interests. This collection has been divided into two series.
