The National WWII Museum has published a guide for researching WWII records entitled “Researching American Military and Civilian Records from World War II,” available at
www.nationalww2meseum.org/war/research-veteran
To quote: “Through this 35-page guide, readers can find a checklist of what is needed to make a request for obtaining a relative’s records; the book even contains a pair of sample forms filled out to show exactly what should be noted in the request. The guide also includes instructions on how to use those records to find more information based on a veteran’s unit, ship, or command.” From the Summer 2018 issue of V...-MAIL, a publication of the museum, p 8.
