[COURYHOUSE at aol.com]

Online versions of signal corps history books-
 
I have always enjoyed   this set of  books and although I  prefer  reading 
the hardbound  versions  when I am away from the  museum's library it is  
nice to be able to refer to these when  needed.
 
"THE TEST"   has  some TTYs 
 
 
three "Green Books" are available for free .PDF  download:
