What do the conditions mean?
Our conditions mean the following:
- New - a brand new book
- Almost New - appears new but is actually secondhand.
- Very Good - only minor imperfections such as minor scuffs to edge or cover or a price written in pencil or shop sticker.
- Standard Secondhand - Clearly been read before, but not too bad. We do not recommend these for gifting. Spines usually creased. Could also include creases or folds to cover, some writing such as in the cover or elsewhere, underlining or highlighting, but might not do. Possibly some stains or marks. Similar in general to books in any secondhand shop or charity shop.
- Poor Condition - Usually this will have a specific problem such as writing inside, water damage, missing dust jacket, heavy staining, large creases or cuts. These are readable copies but not nice ones. On other websites this condition is called 'Acceptable' or 'Fair' , but we want to be more honest.

"Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break," writes David Kahn in this massive (almost 1,200 pages) volume. Most of The Codebreakers focuses on the 20th century, especially World War II. But its reach is long. Kahn traces cryptology's origins to the advent of writing. It seems that as soon as people learned how to record their thoughts, they tried to figure out ways of keeping them hidden. Kahn covers everything from the theory of ciphering to the search for "messages" from outer space. He concludes with a few thoughts about encryption on the Internet.
