Telegraph Code Book Cipher Sale!

Yes I am clearing out the archive again!

A century ago, telegraph or cable codes (aka Commercial Codes) were a method for reducing telegraph costs (they charged per word) and increasing what we now call data security. Technically they were non-secret codes, resolving to commercially available books. But many books wee private and as indecipherable as any OTP. At it's peak there must have been more than a hundred unique codes in use. You can see my current list here. Or buy books below!
