Exactly the type for book I pored over when I was younger! This is a re-read, actually. All sorts of codes, ciphers, invisible inks, as well as books for further reading.

I read something like this--perhaps a later version--when I was a kid in the 1970s. I'm keeping this one, along with the handy encoder/decoder I made for substitution ciphers. I wish I had had someone to exchange coded messages with when I was a kid. I remember trying to write invisibly using lemon juice.

This is a great little book full of lots of information. As a child I had a ton of fun, and it even inspired a science project. This is a great one for all those kids who feel they have a lack of privacy, but make sure not to loose your copy, especially if you use it to write in your diary.

This was the first book on cryptography that I ever bought. I originally bought the abridged edition published by Scholastic many years ago. In fact, it was the seventh book I ever bought for myself. In more recent years, I found a copy of the original, unabridged edition, and I eagerly snatched it up. (I'm pretty certain this was also the first book on cryptography that I ever read as well.)

A few days ago, I was looking over my bookshelves, and decided to give this another read. I wanted to see

Codes and Secret Writing by Herbert Zim is a children’s book. I read it when I was in third grade. It was fascinating. Especially the part about how could figure out what was in a simple substitution message without even knowing the key! Just what the guys needed when one of the communications from those irritating girls in the class was intercepted.

The book sparked my interest in cryptography in general, and over the years, I collected others in the field. They were usually one war behind, but

A really good introduction to codes, ciphers, and secret writing. It's clearly and simply written, presented in a logical order, and sets out the basics of ciphering and deciphering in a very accessible way. My children are often astonished by how much I know about this subject and although I have also read far weightier tomes, it's the contents of this book that equip me with the essentials to answer my children's questions!

Of course, a really dedicated reviewer would have encrypted the review

I loved this book!

It helped me learn a few new ways to write and decipher things. I think I'm ready for Cryptograms but I need to give this book another go-round.

I love codes and references and wordplay and letterplay and cuneiform and stuff like that so this was a great introduction course into the world of words.

Like this is what motivated me to practice learning other languages.

I wish I could find more books like this, honestly.

This book made no sense to me, and was rather a drag to get through.

He wrote a ton of children's books back in the day, I'm nerdy enough to sort of remember this one.
