Yes, good advice. We have a list of research facilities listed in the RESEARCH SECTION. The contact info for NARA in Maryland is listed there, as well as contacts for the Army Corps of Engineers in Alexandria and at Fort Leonard Wood.

I received (via the assistance of a private researcher) approximately 2000 page of reference material on my dad's unit from NARA in Maryland. WOW!
I also received a great deal of material via the Engineer's Office Of History in Alexandria. They were my FIRST BIG find. You can call or write to them. Please let them know I sent you.
Call or write to Fort Leonard Wood too. I was there earlier this year and they have one hell of a library.
In the interim...
See this post. Notice the last entry. I can put you in touch with Joe Izzillo. His book is almost ready for publication. I will send via private email in a few minutes
