From Willa K. Baum's Oral History for the Local Historical Society
1. An interview is not a dialogue. The whole point of the interview is to get the narrator to tell her story. Limit your own remarks to a few pleasantries to break the ice, then brief questions to guide her along. It is not necessary to give her the details of your great-grandmother's trip in a covered wagon in order to get her to tell you about her grandfather's trip to California. Just say, "I understand your grandfather came around the Horn to California. What did he tell you about the trip?"
2. Ask questions that require more of an answer than "yes" or "no." Start with "why," "how," "where," "what kind of ..." Instead of "Was Henry Miller a good boss?" ask "What did the cowhands think of Henry Miller as a boss?"
3. Ask one question at a time. Sometimes interviewers ask a series of questions all at once. Probably the narrator will answer only the first or last one. You will catch this kind of questioning when you listen through the tape after the session, and you can avoid it the next time.
4. Ask brief questions. We all know the irrepressible speech-maker who, when questions are called for at the end of a lecture, gets up and asks five-minute questions. It is unlikely that the narrator is so dull that it takes more than a sentence or two for her to understand the question.
5. Start with questions that are not controversial; save the delicate questions, if there are any, until you have become better acquainted. A good place to begin is with the narrator's youth and background.
6. Don't let periods of silence fluster you. Give your narrator a chance to think of what she wants to add before you hustle her along with the next question. Relax, write a few words on your notepad. The sure sign of a beginning interviewer is a tape where every brief pause signals the next question.
7. Don't worry if your questions are not as beautifully phrased as you would like them to be for posterity. A few fumbled questions will help put your narrator at ease as she realizes that you are not perfect and she need not worry if she isn't either. It is not necessary to practice fumbling a few questions; most of us are nervous enough to do that naturally.
8. Don't interrupt a good story because you have thought of a question, or because your narrator is straying from the planned outline. If the information is pertinent, let her go on, but jot down your questions on your notepad so you will remember to ask it later.
9. If your narrator does stray into subjects that are not pertinent (the most common problems are to follow some family member's children or to get into a series of family medical problems), try to pull her back as quickly as possible. "Before we move on, I'd like to find out how the closing of the mine in 1935 affected your family's finances. Do you remember that?"
10. It is often hard for a narrator to describe people. An easy way to begin is to ask her to describe the person's appearance. From there, the narrator is more likely to move into character description.
