The book is no bigger than the rest of the Collins Gem books, but in this one it ain't a problem. In fact, I think it is better this way. The book itself is great and there is a lot of explanation to the various code and ciphers, including origin, its use, its flaws and strong sides and of course there is a lot of practical examples to each variation of the different codes. I believe it is a must buy for any decoder out there!

As a introduction to crypyology, this book is second to none.
