NSA Hall of Honor, and the other side of which features exhibits honoring those who lost their lives in cryptologic missions represented by the aircraft at NVP as well as others who lost their lives in cryptologic service to America (
USS ''Pueblo'',
USS ''Liberty'', and a replica of NSA's National Cryptologic Memorial
)
In addition, there are galleries throughout NCM focusing on the roles of women and African-Americans in cryptologic history, and the variety of languages in use throughout the world.
The NCM includes an unclassified library of books, papers, and other materials relating to the history of cryptography and cryptology as well.
The library is open on days when the museum is open. The library is non-circulating (that is, material cannot be borrowed or checked out by the public), but photocopying and photography are allowed. Patrons needing extensive or rare materials for research are encouraged to contact the museum to schedule an appointment with the librarian.
The size of NCM's library nearly doubled with the donation of an extensive collection of papers, books, and other artifacts related to codes and ciphers from cryptologic historian and author
David Kahn.
The donation was formally dedicated by the NCM during a recognition ceremony for Dr. Kahn on October 26, 2010.
Activities
The museum offers tours for members of the public, both scheduled and walk-in, that describe cryptology's impact on history and jobs in the field. Tours are led by
docents who are retired NSA employees. Groups of six persons or more are requested to contact the museum in advance to schedule tours and ensure docent availability.
In addition, the NCM offers educational field trips, tours, talks, and interactive programs for students aged from 9, as well as programs for
Boy Scouts
Boy Scouts may refer to:
* Boy Scout, a participant in the Boy Scout Movement.
* Scouting, also known as the Boy Scout Movement.
