Merchandise Description

The Genealogical Proof Standard is something that all genealogists have heard about, but the most unanswered question is how does one really go about following all of the steps?  Thomas W. Jones’ book walks you through each step of the genealogical proof standard and explains why it’s needed and an important part in the research process.  Each chapter covers a step in the genealogical proof standard and concludes with practical exercises to work through that illustrate the various elements which make up the genealogical proof standard.  Answers to the exercises can be found at the end of the book as well as a resource list and glossary of technical terms. 2013. 178 pp. Paperback. National Genealogical Society.
