The CIA Museum, administered by the Center for the Study of Intelligence, is a national archive for the collection, preservation, documentation and exhibition of intelligence artifacts, culture, and history. The collection, which in 2005 numbered 3,500 items, consists of artifacts that have been officially declassified, however since the museum is on the compound of the George Bush Center for Intelligence it is not accessible to the public. Since the museum cannot be visited by the public, the CIA Museum has partnerships with Presidential Libraries and other major museums and institutions to develop public exhibitions dedicated to understanding the craft of intelligence and its role in the broader American experience. The CIA Museum has counterparts at other agencies in the United States Intelligence Community. The National Cryptologic Museum, which is open to the public in Annapolis Junction, Maryland, is the NSA counterpart to the CIA Museum and focuses on cryptology as opposed to human intelligence. On the other hand, the DIA Museum is not public and is housed at its headquarters and focuses on the history of military intelligence and DIA's role. The FBI Museum housed at its headquarters is also off-limits to the public and is focused on its history as a federal law enforcement, counterintelligence, and counter-terrorism organization. Collection The CIA Museum's scope of collection includes material associated with all activities of the CIA's predecessor, the Office of Strategic Services (OSS), material associated with activities of foreign intelligence organizations, and material associated with the history and mission of the Central Intelligence Agency. Articles in the Museum Collection include clothing, equipment, weapons, memorabilia, and insignia designed, manufactured, or used by intelligence organizations historically and presently. The Collection also includes unique items such as weapons, clothing, and equipment developed specifically through research and development, or manufactured by units or individuals to further the mission of intelligence operations. The museum also displays Osama bin Laden's AK-47 along with a brick from the compound he was found in. In September 2022, to mark the agency's 75th anniversary, a small group of journalists were given exclusive access to the museum. BBC journalist Gordon Corera mentioned seeing "cold war spy gadgets" such as "'dead drop rat' in which messages could be hidden, a covert camera inside a cigarette packet, a pigeon with its own spy-camera and even an exploding martini glass." Exhibits As of 2017, The CIA Museum maintains three exhibits of important historical intelligence
