While doing research for some writing I came accross the following site for USAAC, USAAF, and USAF histories:
Air Force Link - Other History Sites
Once at this site go to:
Air Force History Support Office
Then go to:
Our Books and Online Publications
Scroll down and click on Publications by title
All of these items are pdf files but many include images and other details of interest to anyone wishing more information about aircraft and campaigns of the Army Air Corps and Air Forces.
The link below will take you to a list of United States Marine Corps resources available as pdf files.
I hope these will be of use.
