You GO! Jazzo.
One thing I learned as a reporter and Editor is this : People love to tell you what they know about. So don't hesitate to pick up a phone, write a letter or Email to the author of the books, experts in any area of study.
And don't forget your parents, grandparents, and old friends... they are living history books. And don't forget us ... we will be here for you.
Best wishes, wow
