"Codes and Ciphers" is a book by John Laffin, written in 1964.

Codes and Ciphers is a book about, yes, codes and ciphers. Do you know the difference between a code and a cipher? A code is when you have one word represent another (ie. green=hello, blue=friend, green blue=?). A cipher is when you have one letter,number,or symbol that represents a letter (ie. %=a, $=c, @=t, $%@=?). in this book you will find out how to read, write, and decode ciphers. "Codes and Ciphers" includes information on the Ceaser Shift Cipher, Edgar Allen Poe, the Zodiac alphabet, the Shakespeare-Bacon argument, and much more! This is a great book for anyone that is interested in codes and/or ciphers!
