Index

MANY PEOPLE have urged me to put out a paperback edition of The Codebreakers. Here it is.
It comprises about a third of the original. This was as big as the publishers and I could make it and still
keep the price within reason.
In cutting the book, I retained mainly stories about how codebreaking has affected history, particularly
in World War II, and major names and stages in the history of cryptology. I eliminated all source notes and most of the technical matter, as well as material peripheral to strict codebreaking such as biographies, the invention of secondary cipher systems, and miscellaneous uses of various systems.
I had no space for new material, but I did correct the errors reported to me and updated a few items.
The chapters have been slightly rearranged.
Readers wanting to know more about a specific point should consult the text and notes of the original.
If any reader wishes to offer any corrections or to tell me of his own experiences in this field, I would
be very grateful if he would send them to me.
