The Library of Congress is the research library that officially serves the United States Congress, but which is the de facto national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C., and also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center.
By 1990, the Library of Congress became the world's largest library,[n 1] and retains that title today. The Library's "collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 450 languages. Two thirds of the books it acquires each year are in languages other than English."
The Library of Congress moved to Washington in 1800, after sitting for eleven years in the temporary national capitals of New York and Philadelphia. John J. Beckley, who became the first Librarian of Congress, was paid two dollars per day and was also required to serve as the Clerk of the House of Representatives. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s. Most of the original collection had been destroyed by the British in 1814 during the War of 1812. To restore its collection in 1815, the library bought from former president Thomas Jefferson his entire personal collection of 6,487 books.
After a period of slow growth, another fire struck the Library in its Capitol chambers in 1851. again destroying a large amount of the collection, including many of Jefferson's books. The Library of Congress then began to grow rapidly in both size and importance after the American Civil War and a campaign to purchase replacement copies for volumes that had been burned from other sources, collections and libraries (which had begun to speckle throughout the burgeoning United States). The Library received the right of transference of all copyrighted works to have two copies deposited of books, maps, illustrations and diagrams printed in the United States. It also began to build its collections of British and other European works and then of works published throughout the English-speaking world.
This development culminated in the construction during 1888-1894 of a separate, expansive library building across the street from the Capitol, in the Beaux Arts style with fine decorations, murals, paintings, marble halls, columns and steps, carved hardwoods and a stained glass dome. It included several stories built underground of steel and cast iron stacks.
The Library's primary mission of researching inquiries made by members of Congress is carried out through the Congressional Research Service, traces its origin to 1914, and was first permanently authorized (as the Legislative Reference Service) with the Legislative Reorganization Act of 1946.
Although the Library is open to the public, only high-ranking government officials may check out books and materials. The Library promotes literacy and American literature through projects such as the American Folklife Center, American Memory, Center for the Book and Poet Laureate.

Origins and Jefferson's contribution (1800–1851)
James Madison is credited with the idea for creating a congressional library, first making such a proposition in 1783. The Library of Congress was established 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.
As president, Thomas Jefferson played an important role in establishing the structure of the Library of Congress. On January 26, 1802, he signed a bill that allowed the president to appoint an overseer of the Library of Congress and for the establishment of a Joint Committee on the Library to regulate and oversee the Library. The new law also extended to the president and vice president the ability to borrow books. In the midst of the War of 1812, invading British Regulars led a Burning of Washington in August 1814, including the Capitol, and destroyed the Library of Congress and its collection of 3,000 volumes.
Within a month, former president Jefferson offered his personal library as a replacement. Jefferson had spent 50 years accumulating a wide variety of books, in several languages, in many subjects (philosophy, science, literature, architecture) 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 to purchase his 6,487 books. Jefferson's collection was unique in that it was a working collection of a scholar, not a gentleman's collection for display. Jefferson's original collection was organized into a scheme based on Francis Bacon's organization of knowledge. Specifically, he grouped his books into Memory, Reason, and Imagination, which broke down into 44 more subdivisions. The Library followed Jefferson’s organization scheme until the late 19th century, when librarian Herbert Putnam began work on a more flexible Library of Congress Classification structure that now applies to more than 138 million items. In 1851, a fire destroyed two thirds of the Jefferson collection, with only 2,000 books remaining. In 2008, after working for ten years, the librarians at the Library of Congress had found replacements for all but 300 of the works that were in Jefferson's original collection.
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 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 Institution's library of forty thousand volumes to the Library of Congress.
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 by 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.
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 three 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.
Modern history (1939–present)
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 The 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 2014. 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.
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 three 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 titles in all, totaling more than 120,000 issues 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 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—this requirement is known as mandatory deposit. 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 838 miles (1,349 km) of bookshelves, while the British Library reports about 388 miles (624 km) of shelves. The Library of Congress holds more than 155.3 million items with more than 35 million books and other print materials, against approximately 150 million items with 25 million books for the British Library. A 2000 study by information scientists Peter Lyman and Hal Varian suggested that the amount of uncompressed textual data represented by the 26 million books then in the collection was 10 terabytes.
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, an audio book and braille library program provided to more than 766,000 Americans.
Buildings of the Library
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 June 13, 1980.
John Adams Building
The John Adams Building is located between Independence Avenue and East Capitol Street on 2nd Street SE, the block adjacent to the Jefferson Building. The building was originally built simply as an annex to the Jefferson Building. It opened its doors to the public January 3, 1939.
James Madison Memorial Building
The James Madison Memorial Building is located between First and Second Streets on Independence Avenue SE. The building was constructed from 1971 to 1976, and serves as the official memorial to President James Madison.
The Madison Building is also home to the Mary Pickford Theater, the "motion picture and television reading room" of the Library of Congress. The theater hosts regular free screenings of classic and contemporary movies and television shows.
Packard Campus for Audio-Visual Conservation
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.
Digital Millennium Copyright Act
The Library of Congress, through both the Librarian of Congress and the Register of Copyrights, is responsible for authorizing exceptions to Section 1201 of Title 17 of the United States Code as part of the Digital Millennium Copyright Act. This process is done every three years, with the Register receiving proposals from the public and acting as an advisor to the Librarian, who issues a ruling on what is exempt. After three years have passed, the ruling is no longer valid and a new ruling on exemptions must be made.
The library is open for academic research to anyone with a Reader Identification Card. One may not remove library items from the reading rooms or the library buildings.
Since 1902, American libraries 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 system, the Library of Congress has served as a "library of last resort", according to former Librarian of Congress Herbert Putnam. The Library of Congress lends books to other libraries with the stipulation that they be used only inside the borrowing library.
In addition to its library services, the Library of Congress is also actively involved in various standard activities in areas related to bibliographical and search and retrieve standards. Areas of work include MARC standards, METS, Metadata Object Description Schema (MODS), Z39.50 and Search/Retrieve Web Service (SRW), and Search/Retrieve via URL (SRU).
The Law Library of Congress seeks to further legal scholarship by providing opportunities for scholars and practitioners to conduct significant legal research. Individuals are invited to apply for projects which would further the multi-faceted mission of the Law Library in serving the U.S. Congress, other governmental agencies, and the public.

- John Y. Cole argues that it is now the largest and most international library in the world. He attributes that to its highly influential leaders, especially Ainsworth Rand Spofford (1864–97), Herbert Putnam (1899–1939), Luther H. Evans (1945–53), and James H. Billington (1987–). Cole says they "have affirmed and expanded Thomas Jefferson's concept that the Library of Congress is a national institution that should be universal in scope and widely and freely available to everyone."
