That is awesome. Friedman is absolutely the final authority on
"classical" or pre-computer cryptography. I have his "Military
cryptanalysis" books (5 volumes, tho each is sort of thin) and
they really are a complete guide to breaking virtually every kind
of pen&paper cipher that was in use at that time.
This looks like a lot of the same material, (some of it in draft
or pre-release versions) plus a lot of context about the war and
other circumstances that motivated it.
