Citations that involve living people must respect privacy. In our privately-held working notes, we need to record the name and contact information for each person we interview and each person who supplies information that is not publicly available. When we publish or circulate our material, the minimal identifying information for authenticity should be name, city, and state. However, we should not publish or circulate personal contact information, either in print or online, without the authorization of our informants, so long as they are alive. After their deaths, the contact information becomes historical data that can be useful for research purposes.
