The Library of Congress is the research library of the United States Congress, de facto national library of the United States, and the oldest federal cultural institution in the United States. Located in three buildings in Washington, D.C., it is the largest library in the world by shelf space and number of books. The head of the Library is the Librarian of Congress, currently James H. Billington.

The Library of Congress was established by Congress in 1800, and was housed in the United States Capitol for most of the 19th century. After much of the original collection had been destroyed during the War of 1812, Thomas Jefferson sold 6487 books, his entire personal collection, to the library in 1815. After a period of decline during the mid-19th century the Library of Congress began to grow rapidly in both size and importance after the American Civil War, culminating in the construction of a separate library building and the transference of all copyright deposit holdings to the Library. During the rapid expansion of the 20th century the Library of Congress assumed a preeminent public role, becoming a "library of last resort" and expanding its mission for the benefit of scholars and the American people.

The Library's primary mission is researching inquiries made by members of Congress through the Congressional Research Service. Although it is open to the public, only Members of Congress, Supreme Court justices and other high-ranking government officials may check out books. As the de facto national library, the Library of Congress promotes literacy and American literature through projects such as the American Folklife Center, American Memory, Center for the Book and Poet Laureate.

History

Origins and Jefferson's contribution (1800–1851)

The Library of Congress was established on April 24, 1800, when President John Adams signed an Act of Congress providing for the transfer of the seat of government from Philadelphia to the new capital city of Washington. Part of the legislation appropriated $5,000 "for the purchase of such books as may be necessary for the use of Congress ..., and for fitting up a suitable apartment for containing them...." Books were ordered from London and the collection, consisting of 740 books and 3 maps, was housed in the new Capitol.Although the collection covered a variety of topics, the bulk of the materials were legal in nature, reflecting Congress' role as a maker of laws.

Construction of the Thomas Jefferson Building, from July 8, 1888 to May 15, 1894.

Thomas Jefferson played an important role in the Library's early formation, signing into law on January 26, 1802 the first law establishing the structure of the Library of Congress. The law established the presidentially appointed post of Librarian of Congress and a Joint Committee on the Library to regulate and oversee the Library, as well as giving the president and vice president the ability to borrow books. The Library of Congress was destroyed in August 1814, when invading British troops set fire to the Capitol building and the small library of 3,000 volumes within.

Within a month, former President Jefferson offered his personal library as a replacement. Jefferson had spent 50 years accumulating a wide variety of books, including ones in foreign languages and volumes of philosophy, science, literature, and other topics not normally viewed as part of a legislative library, such as cookbooks, writing that, "I do not know that it contains any branch of science which Congress would wish to exclude from their collection; there is, in fact, no subject to which a Member of Congress may not have occasion to refer." In January 1815, Congress accepted Jefferson's offer, appropriating $23,950 for his 6,487 books.

Weakening (1851–1865)

The antebellum period was difficult for the Library. During the 1850s the Smithsonian Institution's librarian Charles Coffin Jewett aggressively tried to move that organization towards becoming the United States' national library. His efforts were blocked by the Smithsonian's Secretary Joseph Henry, who advocated a focus on scientific research and publication and favored the Library of Congress' development into the national library. Henry's dismissal of Jewett in July 1854 ended the Smithsonian's attempts to become the national library, and in 1866 Henry transferred the Smithsonian's forty thousand-volume library to the Library of Congress. 

On December 24, 1851 the largest fire in the Library's history destroyed 35,000 books, about two–thirds of the Library's 55,000 book collection, including two–thirds of Jefferson's original transfer. Congress in 1852 quickly appropriated $168,700 to replace the lost books but not for the acquisition of new materials. This marked the start of a conservative period in the Library's administration under Librarian John Silva Meehan and Joint Committee Chairman James A. Pearce, who worked to restrict the Library's activities. In 1857, Congress transferred the Library's public document distribution activities to the Department of the Interior and its international book exchange program to the Department of State. Abraham Lincoln's political appointment of John G. Stephenson as Librarian of Congress in 1861 further weakened the Library; Stephenson's focus was on non-library affairs, including service as a volunteer aide-de-camp at the battles of Chancellorsville and Gettysburg during the American Civil War. By the conclusion of the war, the Library of Congress had a staff of seven for a collection of 80,000 volumes. The centralization of copyright offices into the United States Patent Office in 1859 ended the Library's thirteen year role as a depository of all copyrighted books and pamphlets.

Spofford's expansion (1865–1897)

The Library of Congress reasserted itself during the latter half of the 19th century under Librarian Ainsworth Rand Spofford, who directed the Library from 1865 to 1897. Aided by an overall expansion of the federal government and a favorable political climate, Spofford built broad bipartisan support for the Library as a national library and a legislative resource, began comprehensively collecting Americana and American literature, and led the construction of a new building to house the Library, and transformed the Librarian of Congress position into one of strength and independence.] Between 1865 and 1870, Congress appropriated funds for the construction of the Thomas Jefferson Building, placed all copyright registration and deposit activities under the Library's control, and restored the Library's international book exchange. The Library also acquired the vast libraries of both the Smithsonian and historian Peter Force, strengthening its scientific and Americana collections significantly. By 1876, the Library of Congress had 300,000 volumes and was tied with Boston Public Library as the nation's largest library. When the Library moved from the Capitol building to its new headquarters in 1897, it had over 840,000 volumes, 40% of which had been acquired through copyright deposit.

A year before the Library's move to its new location, the Joint Library Committee held a session of hearings to assess the condition of the Library and plan for its future growth and possible reorganization. Spofford and six experts sent by the American Library Association, including future Librarian of Congress Herbert Putnam and Melvil Dewey of the New York State Library, testified before the committee that the Library should continue its expansion towards becoming a true national library. Based on the hearings and with the assistance of Senators Justin Morrill of Vermont and Daniel Voorhees of Indiana, Congress more than doubled the Library's staff from 42 to 108 and established new administrative units for all aspects of the Library's collection. Congress also strengthened the office of Librarian of Congress to govern the Library and make staff appointments, as well as requiring Senate approval for presidential appointees to the position.

Post-reorganization (1897–1939)

Main Library of Congress building at the start of the 20th century

The Library of Congress, spurred by the 1897 reorganization, began to grow and develop more rapidly. Spofford's successor John Russell Young, though only in office for two years, overhauled the Library's bureaucracy, used his connections as a former diplomat to acquire more materials from around the world, and established the Library's first assistance programs for the blind and physically disabled.Young's successor Herbert Putnam held the office for forty years from 1899 to 1939, entering into the position two years before the Library became the first in the United States to hold one million volumes. Putnam focused his efforts on making the Library more accessible and useful for the public and for other libraries. He instituted the interlibrary loan service, transforming the Library of Congress into what he referred to as a "library of last resort". Putnam also expanded Library access to "scientific investigators and duly qualified individuals" and began publishing primary sources for the benefit of scholars.

Putnam's tenure also saw increasing diversity in the Library's acquisitions. In 1903 he persuaded President Theodore Roosevelt to transfer by executive order the papers of the Founding Fathers from the State Department to the Library of Congress. Putnam expanded foreign acquisitions as well, including the 1904 purchase of a four-thousand volume library of Indica, the 1906 purchase of G. V. Yudin's eighty-thousand volume Russian library, the 1908 Schatz collection of early opera librettos, and the early 1930s purchase of the Russian Imperial Collection, consisting of 2,600 volumes from the library of the Romanov family on a variety of topics. Collections of Hebraica and Chinese and Japanese works were also acquired. Congress even took the initiative to acquire materials for the Library in one occasion, when in 1929 Congressman Ross Collins of Mississippi successfully proposed the $1.5 million purchase of Otto Vollbehr's collection of incunabula, including one of four remaining perfect vellum copies of the Gutenberg Bible.

In 1914 Putnam established the Legislative Reference Service as a separative administrative unit of the Library. Based in the Progressive era's philosophy of science as a problem-solver, and modeled after successful research branches of state legislatures, the LRS would provide informed answers to Congressional research inquiries on almost any topic. In 1965 Congress passed an act allowing the Library of Congress to establish a trust fund board to accept donations and endowments, giving the Library a role as a patron of the arts. The Library received the donations and endowments of prominent individuals such as John D. Rockefeller, James B. Wilbur and Archer M. Huntington. Gertrude Clarke Whittall donated five Stradivarius violins to the Library and Elizabeth Sprague Coolidge's donations paid for a concert hall within the Library of Congress building and the establishment of an honorarium for the Music Division. A number of chairs and consultantships were established from the donations, the most well-known of which is the Poet Laureate Consultant.

The Library's expansion eventually filled the Library's Main Building despite shelving expansions in 1910 and 1927, forcing the Library to expand into a new structure. Congress acquired nearby land in 1928 and approved construction of the Annex Building (later the John Adams Building) in 1930. Although delayed during the Depression years, it was completed in 1938 and opened to the public in 1939.

When Putnam retired in 1939, President Franklin D. Roosevelt appointed Archibald MacLeish as his successor. Occupying the post from 1939 to 1944 during the height of World War II, MacLeish became the most visible Librarian of Congress in the Library's history. MacLeish encouraged librarians to oppose totalitarianism on behalf of democracy; dedicated the South Reading Room of the Adams Building to Thomas Jefferson, commissioning artist Ezra Winter to paint four themed murals for the room; and established a "democracy alcove" in the Main Reading Room of the Jefferson Building for important documents such as the Declaration, Constitution and Federalist Papers.Even the Library of Congress assisted during the war effort, ranging from the storage of the Declaration of Independence and the United States Constitution in Fort Knox for safekeeping to researching weather data on the Himalayas for Air Force pilots. MacLeish resigned in 1944 to become Assistant Secretary of State, and President Harry Truman appointed Luther H. Evans as Librarian of Congress. Evans, who served until 1953, expanded the Library's acquisitions, cataloging and bibliographic services as much as the fiscal-minded Congress would allow, but his primary achievement was the creation of Library of Congress Missions around the world. Missions played a variety of roles in the postwar world: the mission in San Francisco assisted participants in the meeting that established the United Nations, the mission in Europe acquired European publications for the Library of Congress and other American libraries, and the mission in Japan aided in the creation of the National Diet Library.

Evans' successor L. Quincy Mumford took over in 1953. Mumford's tenure, lasting until 1974, saw the initiation of the construction of the James Madison Memorial Building, the third Library of Congress building. Mumford directed the Library during a period of increased educational spending, the windfall of which allowed the Library to devote energies towards establishing new acquisition centers abroad, including in Cairo and New Delhi. In 1967 the Library began experimenting with book preservation techniques through a Preservation Office, which grew to become the largest library research and conservation effort in the United States. Mumford's administration also saw the last major public debate about the Library of Congress' role as both a legislative library and a national library. A 1962 memorandum by Douglas Bryant of the Harvard University Library, compiled at the request of Joint Library Committee chairman Claiborne Pell, proposed a number of institutional reforms, including expansion of national activities and services and various organizational changes, all of which would shift the Library more towards its national role over its legislative role. Bryant even suggested possibly changing the name of the Library of Congress, which was rebuked by Mumford as "unspeakable violence to tradition". Debate continued within the library community until the Legislative Reorganization Act of 1970 shifted the Library back towards its legislative roles, placing greater focus on research for Congress and congressional committees and renaming the Legislative Reference Service to the Congressional Research Service.

After Mumford retired in 1974, Gerald Ford appointed Daniel J. Boorstin as Librarian. Boorstin's first challenge was the move to the new Madison Building, which took place between 1980 and 1982. The move released pressures on staff and shelf space, allowing Boorstin to focus on other areas of Library administration such as acquisitions and collections. Taking advantage of steady budgetary growth, from $116 million in 1975 to over $250 million by 1987, Boorstin actively participated in enhancing ties with scholars, authors, publishers, cultural leaders, and the business community. His active and prolific role changed the post of Librarian of Congress so that by the time he retired in 1987, the New York Times called it "perhaps the leading intellectual public position in the nation." Ronald Reagan appointed James H. Billington as the thirteenth Librarian of Congress in 1987, a post he holds as of 2011. Billington took advantage of new technological advancements and the Internet to link the Library to educational institutions around the country in 1991. The end of the Cold War also enabled the Library to develop relationships with newly open Eastern European nations, helping them to establish parliamentary libraries of their own.

In the mid-1990s, under Billington's leadership, the Library of Congress began to pursue the development of what it called a "National Digital Library," part of an overall strategic direction that has been somewhat controversial within the library profession. In late November 2005, the Library announced intentions to launch the World Digital Library, digitally preserving books and other objects from all world cultures. In April 2010, it announced plans to archive all public communication on Twitter, including all communication since Twitter's launch in March 2006.

Holdings

The collections of the Library of Congress include more than 32 million cataloged books and other print materials in 470 languages; more than 61 million manuscripts; the largest rare book collection in North America, including the rough draft of the Declaration of Independence, a Gutenberg Bible (one of only four perfect vellum copies known to exist); over 1 million US government publications; 1 million issues of world newspapers spanning the past three centuries; 33,000 bound newspaper volumes; 500,000 microfilm reels; over 6,000 comic book titles; films; 5.3 million maps; 6 million works of sheet music; 3 million sound recordings; more than 14.7 million prints and photographic images including fine and popular art pieces and architectural drawings; the Betts Stradivarius; and the Cassavetti Stradivarius.

The Library developed a system of book classification called Library of Congress Classification (LCC), which is used by most US research and university libraries, although most public libraries continue to use the Dewey decimal system.

The Library serves as a legal repository for copyright protection and copyright registration, and as the base for the United States Copyright Office. Regardless of whether they register their copyright, all publishers are required to submit two complete copies of their published works to the Library if requested—this requirement is known as mandatory deposit. Parties wishing not to publish, need only submit one copy of their work. Nearly 22,000 new items published in the U.S. arrive every business day at the Library. Contrary to popular belief, however, the Library does not retain all of these works in its permanent collection, although it does add an average of 10,000 items per day. Rejected items are used in trades with other libraries around the world, distributed to federal agencies, or donated to schools, communities, and other organizations within the United States. As is true of many similar libraries, the Library of Congress retains copies of every publication in the English language that is deemed significant.

The Library of Congress states that its collection fills about 745 miles (1,199 km), while the British Library reports about 388 miles (625 km) of shelves. The Library of Congress holds about 130 million items with 29 million books against approximately 150 million items with 25 million books for the British Library.

The Library makes millions of digital objects, comprising tens of petabytes, available at its American Memory site. American Memory is a source for public domain image resources, as well as audio, video, and archived Web content. Nearly all of the lists of holdings, the catalogs of the library, can be consulted directly on its web site. Librarians all over the world consult these catalogs, through the Web or through other media better suited to their needs, when they need to catalog for their collection a book published in the United States. They use the Library of Congress Control Number to make sure of the exact identity of the book.

The Library of Congress also provides an online archive of the proceedings of the U.S. Congress at THOMAS, including bill text, Congressional Record text, bill summary and status, the Congressional Record Index, and the United States Constitution.

The Library also administers the National Library Service for the Blind and Physically Handicapped, a talking and braille library program provided to more than 766,000 Americans.

Buildings of the Library

Jefferson Building

Madison Building

The Library of Congress is physically housed in three buildings on Capitol Hill and a conservation center in rural Virginia. The Library's Capitol Hill buildings are all connected by underground passageways, so that a library user need pass through security only once in a single visit. The library also has off-site storage facilities for less commonly-requested materials.

Thomas Jefferson Building

The Thomas Jefferson Building is located between Independence Avenue and East Capitol Street on First Street SE. It first opened in 1897 as the main building of the Library and is the oldest of the three buildings. Known originally as the Library of Congress Building or Main Building, it took its present name on June 13, 1980.

John Adams Building

The John Adams Building is located between Independence Avenue and East Capitol Street on 2nd Street SE. It opened in 1938 as an annex to the main building. Between April 13, 1976 and June 13, 1980, the John Adams Building was known as the Thomas Jefferson Building.

James Madison Memorial Building

The James Madison Memorial Building is located between First and Second Streets on Independence Avenue SE. It opened on May 28, 1980 as the new headquarters of the Library. The James Madison Memorial Building also serves as the official memorial to James Madison. It houses, among other materials, the Law Library of Congress.

Packard Campus for Audio-Visual Conservation

National Audio-Visual Conservation Center

The Packard Campus for Audio-Visual Conservation is the Library of Congress's newest building, opened in 2007 and located in Culpeper, Virginia. It was constructed out of a former Federal Reserve storage center and Cold War bunker. The campus is designed to act as a single site to store all of the library's movie, television, and sound collections. It is named to honor David Woodley Packard, whose Packard Humanities Institute oversaw design and construction of the facility. The centerpiece of the complex is a reproduction Art Deco movie theater that presents free movie screenings to the public on a semi-weekly basis.

Using the Library

Library of Congress reading room

The library is open to the general public for academic research and tourists. Only those who are issued a Reader Identification Card may enter the reading rooms and access the collection. The Reader Identification Card is available in the Madison building to persons who are at least 16 years of age upon presentation of a government issued picture identification (e.g. driver's license, state ID card or passport). However, only members of Congress, Supreme Court Justices, their staff, Library of Congress staff and certain other government officials can actually remove items from the library buildings. Members of the general public with Reader Identification Cards must use items from the library collection inside the reading rooms only; they cannot remove library items from the reading rooms or the library buildings.

Since 1902, libraries in the United States have been able to request books and other items through interlibrary loan from the Library of Congress if these items are not readily available elsewhere. Through this, the Library of Congress has served as a "library of last resort", according to former Librarian of Congress Herbert Putnam.

Librarians of Congress

The Librarian of Congress is the head of the Library of Congress, appointed by the President of the United States with the advice and consent of the Senate. He serves as the chief librarian of all the sections of the Library of Congress. One of the responsibilities of the Librarian of Congress is to appoint the U.S. Poet Laureate.

North American Aerospace Defense Command (NORAD, pronounced /ˈnɒræd/ NORR-ad) is a joint organization of Canada and the United States that provides aerospace warning, air sovereignty, and defense for the two countries. It was founded on May 12, 1958 (an effect of the Cold War) as a joint command between the governments of Canada and the United States, as the North American Air Defense Command. Its main technical facility has been the Cheyenne Mountain Directorate, formerly Cheyenne Mountain Operations Center, of the Cheyenne Mtn. Air Force Station, Colorado; and for this reason NORAD is sometimes referred to as Cheyenne Mountain. Similar to the Cheyenne Mountain Directorate, but on a smaller scale, the Canada East and Canada West Sector Air Operations Control Centres were located in an underground complex 600 feet below the surface at Canadian Forces Base (CFB) North Bay in Ontario, Canada. On October 12, 2006, NORAD operations at CFB North Bay have officially moved above ground into the newly-constructed Sergeant David L. Pitcher Building, and the underground complex has been "mothballed" but can be returned to operation if it should be needed again.

NORAD's headquarters facilities in Colorado are administered by the U.S. Air Force under the command of the 721st Mission Support Group, part of the 21st Space Wing, headquartered at Peterson Air Force Base. NORAD's forces consist of the Alaskan NORAD Region/Eleventh Air Force, Canadian NORAD Region, and Continental NORAD Region.

History

Formation

NORAD Headquarters Building,

The growing perception of the threat of long-range Soviet strategic bombers armed with nuclear weapons brought the U.S. and Canada into closer cooperation for air defense. While attacks from the Pacific or Atlantic would have been detected by Airborne Early Warning aircraft, Navy ships, or offshore radar platforms, the Arctic was underprotected. In the early 1950s the U.S. and Canada agreed to construct a series of radar stations across North America to detect a Soviet attack over the Arctic. The first series of radars was the Pinetree Line, completed in 1954 and consisting of 33 stations across southern Canada. However, technical defects in the system led to more radar networks being built. In 1957, the McGill Fence was completed; it consisted of Doppler radar for the detection of low-flying craft. This system was roughly 300 miles (480 km) north of the Pinetree Line along the 55th parallel north. The third joint system was the Distant Early Warning Line (DEW Line), also completed in 1957. This was a network of 58 stations along the 69th parallel north. The systems gave around three hours' warning of a bomber attack before they could reach any major population center.

The command and control of the massive system then became a significant challenge. Discussions and studies of joint systems had been ongoing since the early 1950s and culminated on August 1, 1957, with the announcement by the U.S. and Canada to establish an integrated command, the North American Air Defense Command. On September 12, operations commenced in Colorado. A formal NORAD agreement between the two governments was signed on May 12, 1958.

On June 16, 1961, the official groundbreaking ceremony was held at the construction site of the NORAD Combat Operations Center (COC). Gen. Laurence S. Kuter, NORAD Commander, and Lt. Gen. Robert Merrill Lee, ADC Commander, simultaneously set off symbolic dynamite charges.

Cold War and false alarms

NORAD blast doors, Cheyenne Mountain, Colorado,

By the early 1960s, about 250,000 personnel were involved in the operation of NORAD. The emergence of the intercontinental ballistic missile (ICBM) and submarine-launched ballistic missile (SLBM) threat in the early 1960s was something of a blow. In response, a space surveillance and missile warning system was constructed to provide worldwide space detection, tracking and identification. The extension of NORAD's mission into space led to a name change, the North American Aerospace Defense Command in March 1981.

From 1963, the size of the U.S. Air Force was reduced, and obsolete sections of the radar system were shut down. However, there was increased effort to protect against an ICBM attack; two underground operations centers were set up, the main one inside Cheyenne Mountain and an alternate at North Bay, Ontario. By the early 1970s, the acceptance of mutual assured destruction doctrine led to a cut in the air defense budget and the repositioning of NORAD's mission to ensuring the integrity of airspace during peacetime. There followed significant reductions in the air defense system until the 1980s, when, following the 1979 Joint US-Canada Air Defense Study (JUSCADS) the need for the modernization of air defenses was accepted—the DEW Line was to be replaced with an improved Arctic radar line called the North Warning System (NWS); there was to be the deployment of Over-the-Horizon Backscatter (OTH-B) radar; the assignment of more advanced fighters to NORAD, and the greater use of Airborne Warning and Control System (AWACS) aircraft from Tinker Air Force Base in Oklahoma or Elmendorf Air Force Base in Alaska. These recommendations were accepted by the governments in 1985. The United States Space Command was formed in September 1985 as an adjunct but not a component of NORAD.

Even though all equipment in Cheyenne Mountain was put through a rigorous inspection, on at least three occasions, failure in its systems could have potentially caused nuclear war. On November 9, 1979, a technician in NORAD loaded a test tape but failed to switch the system status to "test", causing a stream of constant false warnings to spread to two "continuity of government" bunkers as well as command posts worldwide. On June 3, 1980, and again on June 6, 1980, a computer communications device failure caused warning messages to sporadically flash in U.S. Air Force command posts around the world that a nuclear attack was taking place. During these incidents, Pacific Air Forces properly had their planes (loaded with nuclear bombs) in the air; Strategic Air Command did not and took criticism because they did not follow procedure, even though the SAC command knew these were almost certainly false alarms (as did PACAF). Both command posts had recently begun receiving and processing direct reports from the various radar, satellite, and other missile attack detection systems, and those direct reports simply didn't match anything about the erroneous data received from NORAD.

Post-Cold War

At the end of the Cold War NORAD reassessed its mission. To avoid cutbacks, from 1989 NORAD operations expanded to cover counter-drug operations, especially the tracking of small aircraft entering and operating within America and Canada (although commercial flights were not perceived to be threats). But the DEW line sites were still replaced, in a scaled-back fashion by the North Warning System radars between 1986 and 1995. The Cheyenne Mountain site was also upgraded. However, none of the proposed OTH-B radars are currently in operation.

Post-September 11, 2001 attacks

Command center of NORAD,

After the September 11, 2001 attacks, the NORAD mission evolved to include monitoring of all aircraft flying in the interior of the United States. NORAD oversees Operation Noble Eagle using fighter aircraft Combat Air Patrols (CAP) under command of First Air Force and Airborne Warning and Control System (AWACS) E-3 Sentry aircraft under command of the 552nd Air Control Wing. At U.S. request, NATO deployed five of its NATO AWACS aircraft to the U.S. to help NORAD in the aftermath of the September 11 attacks.

On July 28, 2006, military officials announced that NORAD's day-to-day operations would be consolidated, for purposes of efficiency, in an ordinary building at Peterson Air Force Base in nearby Colorado Springs. The mountain will be kept only as a backup in "warm standby," though fully operational and staffed with support personnel should the need arise. NORAD officials stated that the same surveillance work can be continued without the security the facility provides. They emphasized that they are no longer concerned about a halt to their operations from an intercontinental nuclear attack.

NORAD commander Admiral James A. Winnefeld, Jr. said in 2010 that NORAD did not send interceptors to intercept every flight of Russian bombers near U.S. airspace because NORAD did not wish to feed Russia's propaganda about their illusion of power.

Commanders and deputy commanders

The Commander of NORAD is always an United States Defense Department Officer confirmed by the US Senate and from 2002 has simultaneously headed USNORTHCOM, while the Deputy Commander is always Canadian. During the course of NORAD's history there have been four different U.S. combatant commands associated with NORAD:

Notable popular culture

NORAD comes to the public's attention during December and on Christmas Eve, when its NORAD Tracks Santa service follows Santa Claus on his journey around the world. This tradition started in 1955 when a local Sears store in Colorado misprinted the telephone number and children thought they were calling Santa, but actually were calling Air Defense Command (NORAD's predecessor) instead.

Cheyenne Mountain was the central setting of the 1983 motion picture WarGames, starring Matthew Broderick as a teenager who hacked NORAD's main computer and almost started a global thermonuclear war.

Cheyenne Mountain is also the main earth setting of the Stargate universe, serving as the Command Center for all Stargate Operations in the Milky Way Galaxy.
