[Milsurplus] Signal Corps books

[J. Forster]

Is anyone familiar with the three volume set of books titled "US Army in World
War II, The Technical Services" ?

The volumes are:

Vol 1 The Signal Corps: The Emergency (by Dulany and Turrett, 1956) 383 pages
Vol 2 The Signal Corps: The Test (by Thompson, Harris, Oakes, and Turrett, 1957)
621 pages
Vol 3 The Signal Corps: The Outcome (by Thompson and Harris, 1966) 720 pages

My question is this: Do the books describe development of the common systems in
any technical way, or are they just a chronicle of General Fubar visited Fort
Boondock and inspected the First and Third Battalions and signed contract xxxxx
sort of thing?

Thanks,
-John
