Format:Paperback
As a former codebreaker with the ASA/NSA during the VN war, I often found it helpful to have a copy of Helen's book handy, and spent many enjoyable hours solving the sample ciphers provided. This valuable book not only describes many historically significant encipherment methods, but also goes into detail about how to break them. Afficianados of manual ciphers might also wish to contact others with similar interests and can do so through the American Cryptogram Association at www.cryptogram.org.
Format:Paperback
I bought this book over 40 years ago... It is, by far, the best book for pen-and-pencil cryptogram solving that I have found. It gives sufficient information to allow attacking any pen-and-pencil cryptogram. If it is followed by Bauer's "Decrypted Secrets," one would have a very thorough introduction to methods of solutions (Bauer is quite mathematical, but also recommended to the mathematically inclined). An excellent introduction with a great deal of useful information that is probably the best available source for pre-computer techniques.
Format:Paperback
The author of this book was party to a cryptological society, still around, founded in the early 1920's which made, and solved, cryptograms as a hobby just as people 'do' crossword puzzles.
All crypto can, loosely, be divided into the sort used by governments, banks, international drug traffickers, and those using digital communications and that type of crypto used by people who just don't want secretaries, nosey people or their teacher peeking into their lives.
This book will most likely cover all the later groups crypto needs. I have used it, almost exclusively, for 30 years, where fast and short communication was needed to a known recipient with a decryption 'key'.
This book uses complex English and print which is uncomfortably small. There are some 'gems' of obscure information in this book as, by example, a frequency list which identifies the final letter of 10,000 typical words in Portuguese ... O.K. ... nothing I suspect that one could not 'figure out' but nothing I suspect that one ever would.
While a trained crypto analyst might unravel these in short order they are impenetrable to most secretaries, nosey folks and schoolteachers.

An excellent practical guide to cryptogram solving
I don't remember where I got this from, but it it really excellent. It covers various common classical cryptographic techniques such as transposition, simple substitution,... Read more

Very interesting and readable book. However, it has rather small print.
