Query: The book I recommend to anyone interested in family stories.

As president of the Association of Personal Historians (an international network of professionals who help others preserve their life stories and family history), I was often asked to recommend books for people interested either in preserving their own family history or in getting into the business of doing this for others. There are many books on this topic, but Vera Rosenbluth's excellent book was always my number one recommendation. It is well-written, easy to understand and filled with helpful information.
