Leading military historian and researcher, Jonathan Gawne, explains and shares the techniques he uses to research archives, libraries, veteran associations and myriad other sources of information to track down the wartime career of an individual.

I found a copy at my local Barnes and Noble. It’s also available at Amazon.com.
