can you scan the 1960's material to .doc or .pdf?
Best single nuke prep book, IMO, is "Nuclear War Survival Skills" published originally by Oak Ridge National Laboratory. Free on-line copy is here...

I googled "1961 civil defense pamphlet" with out quotes, and found a lot of interesting stuff.
This site had an 8 page pamhlet from (I think) 1955.

Here is an excellent one fron January 1951, I think it takes that adult tone we mentioned.
