The only people who listen to the interviews are those doing language studies under Hans Boas’ direction. Special permission must be granted by the interviewee if the interview is to be used by anyone else for any other purpose. Taped interviews are given coded labels and stored in a locked office to further protect the privacy of each interviewee. When parts of interviews are used for educational purposes such as academic conferences, class presentations, or for presentation over the Internet (for wider accessibility), the privacy of interviewees is guaranteed.
