The National Cryptologic Museum holds a large collection of machines, books, and other artifacts relating to cryptography and code-breaking. Situated in Maryland, USA, the Museum is dedicated to 'the exploitation of enemy cryptology and the protection of American communications'. Exhibits include German Enigma machines used in the Second World War, a cipher-wheel that may or may not have been connected with Thomas Jefferson, early computers, and a collection of rare books. There are also several special exhibitions described and illustrated at the website. The site provides an interesting overview of some of the technologies used in the intelligence industry.
