The Ralph Leon Beals papers are open for research. At Ralph Beals' request, his 1930-1933 correspondence were restricted until 2000. These include letters to and from his wife while he was in the field, several letters to his children, and one letter to his mother-in-law. Beals supplied edited copies of the restricted letters for public access. The restrictions have since been lifted, and the edited copies have been retained with the original letters. His field assistants' materials have been restricted for the lifetime of the creators.
Access to the Ralph Leon Beals papers requires an appointment.
