The National Cryptologic Museum has had an adjunct reference library since it opened in 1993. The library not only supports the exhibits, but also encourages visitors to research various areas of cryptologic history. Over the years, the library has become an important resource to students, scholars, and those with an interest in this once secret world.
The Museum Library maintains a collection of unclassified and declassified books and documents relating to every aspect of cryptology. The books and records complement the museum exhibits and artifacts, but also offer unique and in-depth sources of information for researchers.
