Celebrate African American History Month!
Carter Godwin Woodson (1875-1950) was one of the first scholars to study African American history and the founder of Negro History Week, first celebrated in 1925. President Gerald Ford expanded the celebration to Black History Month in 1975, famously reminding Americans to “Seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history."

Library of Congress, the de facto national library of the United States and the largest library in the world. Its collection was growing at a rate of about two million items per year it reached more than 155 million items in 2012. The Library of Congress serves members, committees, and staff of the U.S. Congress, other government agencies, libraries throughout the country and the world, and the scholars, researchers, artists, and scientists who use its resources. It is the national centre for library service to the blind and physically handicapped, and it offers many concerts, lectures, and exhibitions for the general public. Those outside the Washington, D.C., area have access to the library’s growing electronic resources through the Library of Congress Web site at http://www.loc.gov.
The library was founded on April 24, 1800, when U.S. Pres. John Adams approved the $5,000 appropriated by Congress when the U.S. capital moved from Philadelphia, Pennsylvania, to Washington, D.C. It was housed within the new Capitol building, where it remained for nearly a century. However, on August 24, 1814, during the War of 1812, the library’s original collection of 3,000 volumes was destroyed when the British burned the Capitol as well as the White House. To rebuild the library’s collection, Congress, on January 30, 1815, approved the purchase of former president Thomas Jefferson’s personal library of 6,487 books for $23,950. On Christmas Eve 1851, another fire destroyed two-thirds of the collection. Many of the volumes have since been replaced.
Librarian of Congress Ainsworth Rand Spofford (1864–97) was the first to propose that the library be moved to a dedicated building. He also was instrumental in establishing the copyright law of 1870, which placed the Copyright Office in the Library of Congress and required anyone seeking a copyright to provide two copies of the work—books, pamphlets, maps, photographs, music, and prints—to the library.
Largely as a result of Spofford’s vision, the library’s burgeoning collection outgrew its space in the Capitol. In the early 21st century the Library of Congress complex on Capitol Hill included three buildings containing 21 public reading rooms. The Thomas Jefferson Building (originally called the Congressional Library, or Main Building) houses the Main Reading Room. Designed in Italian Renaissance style, it was completed in 1897 and magnificently restored 100 years later. The John Adams Building, completed in 1939, received its current name in 1980 to honour the president who in 1800 signed the act of Congress establishing the library. The Adams Building was built in Art Deco style and faced with white Georgia marble. The James Madison Memorial Building, modern in style, was dedicated in 1980. (That same year the Main Building was designated the Thomas Jefferson Building.) The Madison Building more than doubled the library’s available Capitol Hill space. The continued growth of the collection in a wide variety of formats during the 1980s and ’90s necessitated the off-site relocation of some materials to storage facilities in Fort Meade, Maryland, and to the Packard Campus for Audio Visual Conservation Center in Culpeper, Virginia, the library’s state-of-the-art facility for audiovisual preservation.
On an average workday, the library receives approximately 15,000 items and adds approximately 11,000 of these to its collections. The vast majority of works in the library’s collections are received through the copyright deposit process mentioned above. Materials are also acquired through gifts, purchases, and donations from private sources and other government agencies (state, local, and federal), the library’s Cataloging in Publication program (a prepublication arrangement with publishers), and exchanges with libraries in the United States and abroad. Those items that are not selected for the library’s collections or exchange programs are offered free to other federal agencies, educational institutions, public libraries, or nonprofit, tax-exempt organizations. Between 2008 and 2012 the number of cataloged books and other print materials increased from 32 million to 35.8 million, manuscripts from 61 million to 68 million, maps from 5.3 million to 5.5 million, sheet music from 5.5 million to 6.6 million, audio materials from nearly 3 million to 3.4 million, and visual materials from 14 million to 15.7 million.
Approximately half of the library’s book and serial collections are in languages other than English. Some 470 languages are represented. Particularly noteworthy are the library’s preeminent collections in Arabic, Spanish, and Portuguese the largest collections in many Slavic and Asian languages outside those geographic areas the world’s largest law library and the largest rare-book collection in North America (more than 700,000 volumes), including the most comprehensive collection of 15th-century books in the Western Hemisphere. The Manuscript Division holds the papers of 23 U.S. presidents, ranging in time from George Washington to Calvin Coolidge, along with those of many Supreme Court justices and other high-ranking government officials, of inventors such as Alexander Graham Bell and the Wright brothers, of social reformers such as Susan B. Anthony and Frederick Douglass, and of cultural figures such as Walt Whitman, Irving Berlin, and Martha Graham.
The Library of Congress provides direct research assistance to the U.S. Congress through the Congressional Research Service (originally the Legislative Reference Service), which was founded in 1914. Established in 1832, the Law Library provides Congress with comprehensive research on foreign, comparative, international, and U.S. law, drawing upon its collection of some 2.8 million volumes.
The Library of Congress is supported by direct appropriations from Congress—as well as gifts and private donations—and has been governed since 1800 by the Joint Committee on the Library of Congress. Established in 1990, the James Madison Council—the library’s first private-sector advisory group—has supported the acquisition of hundreds of collection items (such as the 1507 map by the German cartographer Martin Waldseemüller that first used the word “America”) and initiatives such as the annual National Book Festival (launched in 2001). The council’s first chairman, John W. Kluge, also endowed a major scholarly centre and a $1 million prize for lifetime achievement in the humanities.
In addition to the Kluge Prize, the library sponsors many privately endowed honours and awards recognizing creativity and achievement in the humanities. These include the poet laureate position, the Living Legend medal, the Gershwin Prize for Popular Song, and the national Ambassador for Young People’s Literature, through which the library honours those who have advanced and embodied the ideals of individual creativity with conviction, dedication, scholarship, and exuberance.
In 1994 the Library of Congress launched the National Digital Library Program (NDLP), making freely available on the Internet high-quality electronic versions of American historical material from the library’s special collections. By the end of the library’s bicentennial year in 2000, more than five million items (manuscripts, films, sound recordings, and photographs) had been mounted on the library’s American Memory Web site, which continued to expand rapidly. By 2012 the site had grown to include some 37.6 million primary source files, which were available for classroom use by educators as part of the library’s Teaching with Primary Sources Program. Also accessible on the Web site are the library’s exhibitions, bibliographic databases (online public access catalog and online print and photograph catalog), a comprehensive public legislative information system known as Congress.gov, copyright information, and a Global Gateway Web site for the library’s international collections and collaborative digital libraries built with international partners.
Inspired by the success of the Global Gateway site, in 2005 Librarian of Congress James H. Billington proposed a project called the World Digital Library. Its goal was to make available to anyone with access to the Internet digitized texts and images of “unique and rare materials from libraries and other cultural institutions around the world.” It was designed to be searchable in seven languages—Arabic, Chinese, English, French, Russian, and Spanish (official languages of the United Nations), as well as Portuguese. In 2007 the Library of Congress and UNESCO signed an agreement to build a World Digital Library Web site, which was launched in 2009 with approximately 1,200 digitized exhibits, including books, maps, and paintings. In 2012, 161 partners in 75 countries provided content to the site. The library is also leading the National Digital Information Infrastructure and Preservation Program, a collaborative effort mandated in 2000 by Congress to preserve the country’s digital assets.
The Continental Congress adopted the Articles of Confederation, the first constitution of the United States, on November 15, 1777. However, ratification of the Articles of Confederation by all thirteen states did not occur until March 1, 1781. The Articles created a loose confederation of sovereign states and a weak central government, leaving most of the power with the state governments. The need for a stronger Federal government soon became apparent and eventually led to the Constitutional Convention in 1787. The present United States Constitution replaced the Articles of Confederation on March 4, 1789.
Fire ravages Library of Congress
A devastating fire at the Library of Congress in Washington, D.C., destroys about two-thirds of its 55,000 volumes, including most of Thomas Jefferson’s personal library, sold to the institution in 1815.
The Library of Congress was established in 1800, when President John Adams approved legislation that appropriated $5,000 to purchase “such books as may be necessary for the use of Congress.” The first books, ordered from London, arrived in 1801 and were stored in the U.S. Capitol, the library’s first home. The first library catalog, dated April 1802, listed 964 volumes and nine maps. Twelve years later, the British army invaded the city of Washington and burned the Capitol, including the 3,000-volume Library of Congress.
Former president Thomas Jefferson, who advocated the expansion of the library during his two terms in office, responded to the loss by selling his personal library, the largest and finest in the country, to Congress to “recommence” the library. The purchase of Jefferson’s 6,487 volumes was approved in the next year, and a professional librarian, George Watterston, was hired to replace the House clerks in the administration of the library. In 1851, a second major fire at the library destroyed about two-thirds of its books. Congress responded quickly and generously to the disaster, and within a few years a majority of the lost books were replaced.
After the Civil War, the collection was greatly expanded, and by the 20th century the Library of Congress had become the de facto national library of the United States and one of the largest in the world. Today, the collection, housed in three enormous buildings in Washington, contains more than 39 million books, as well as millions of maps, manuscripts, photographs, films, audio and video recordings, prints and drawings.
1800–1851: Origin and Jefferson's contribution Edit
James Madison of Virginia is credited with the idea of creating a congressional library, first making such a proposition in 1783.  The Library of Congress was subsequently established on April 24, 1800, when President John Adams signed an act of Congress also 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 consisted of 740 books and three maps, which were housed in the new United States Capitol. 
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 the librarian of Congress and establishing a Joint Committee on the Library to regulate and oversee it. The new law also extended borrowing privileges to the president and vice president.  
In August 1814, after routing an American militia at Bladensburg, the British bloodlessly occupied Washington, D.C. In retaliation for the American destruction of Port Dover, the British ordered the destruction of numerous public buildings in the city. British troops burned the Library of Congress, including its collection of 3,000 volumes.  These volumes had been held in the Senate wing of the Capitol.   One of the few congressional volumes to survive was a government account book of receipts and expenditures for 1810.  It was taken as a souvenir by British naval officer Sir George Cockburn, whose family returned it to the United States government in 1940. 
Within a month, Thomas Jefferson offered to sell his large personal library   as a replacement. Congress accepted his offer in January 1815, appropriating $23,950 to purchase his 6,487 books.  Some members of the House of Representatives opposed the outright purchase, including New Hampshire representative Daniel Webster. He wanted to return "all books of an atheistical, irreligious, and immoral tendency." 
Jefferson had spent 50 years accumulating a wide variety of books in several languages, and on subjects such as philosophy, history, law, religion, architecture, travel, natural sciences, mathematics, studies of classical Greece and Rome, modern inventions, hot air balloons, music, submarines, fossils, agriculture, and meteorology.  He had also collected books on topics not normally viewed as part of a legislative library, such as cookbooks. But, he believed that all subjects had a place in the Library of Congress. He remarked:
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. 
Jefferson's collection was unique in that it was the working collection of a scholar, not a gentleman's collection for display. With the addition of his collection, which doubled the size of the original library, the Library of Congress was transformed from a specialist's library to a more general one.  His original collection was organized into a scheme based on Francis Bacon's organization of knowledge. Specifically, Jefferson had grouped his books into Memory, Reason, and Imagination, and broke them 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. This now applies to more than 138 million items.
1851–1865: Weakening Edit
On December 24, 1851, the largest fire in the library's history destroyed 35,000 books, about two–thirds of the library's collection and two-thirds of Jefferson's original transfer.  Congress appropriated $168,700 to replace the lost books in 1852 but not to acquire new materials  (By 2008, the librarians of Congress had found replacements for all but 300 of the works that had been documented as being in Jefferson's original collection.  ) 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 restricted the library's activities.  Meehan and Pearce's views about a restricted scope for the Library of Congress reflected those shared by members of Congress. While Meehan was librarian, he supported and perpetuated the notion that "the congressional library should play a limited role on the national scene and that its collections, by and large, should emphasize American materials of obvious use to the U.S. Congress."  In 1859, 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. 
During the 1850s, Smithsonian Institution librarian Charles Coffin Jewett aggressively tried to develop the Smithsonian as the United States' national library. His efforts were blocked by Smithsonian secretary Joseph Henry, who advocated a focus on scientific research and publication.  To reinforce his intentions for the Smithsonian, Henry established laboratories, developed a robust physical sciences library, and started the Smithsonian Contributions to Knowledge, the first of many publications intended to disseminate research results.  For Henry, the Library of Congress was the obvious choice as the national library. Unable to resolve the conflict, Henry dismissed Jewett in July 1854.
In 1865 the Smithsonian building, also called the Castle due to its Norman architectural style, was severely damaged by fire. This incident presented Henry with an opportunity related to the Smithsonian's non-scientific library. Around this time, the Library of Congress was making plans to build and relocate to the new Thomas Jefferson Building, designed to be fireproof.  Authorized by an act of Congress, Henry transferred the Smithsonian's non-scientific library of 40,000 volumes to the Library of Congress in 1866. 
President Abraham Lincoln appointed John G. Stephenson as librarian of Congress in 1861 the appointment is regarded as the most political to date.  Stephenson was a physician and spent equal time serving as librarian and as a physician in the Union Army. He could manage this division of interest because he hired Ainsworth Rand Spofford as his assistant.  Despite his new job, Stephenson focused on the war. Three weeks into his term as Librarian of Congress, he left Washington, D.C. to serve as a volunteer aide-de-camp at the battles of Chancellorsville and Gettysburg during the American Civil War.  Stephenson's hiring of Spofford, who directed the library in his absence, may have been his most significant achievement. 
1865–1897: Spofford's expansion Edit
Librarian Ainsworth Rand Spofford, who directed the Library of Congress from 1865 to 1897, built broad bipartisan support to develop it as a national library and a legislative resource. He was aided by expansion of the federal government after the war and a favorable political climate. He began comprehensively collecting Americana and American literature, 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 international book exchange. The library also acquired the vast libraries of the Smithsonian and of historian Peter Force, strengthening its scientific and Americana collections significantly. By 1876, the Library of Congress had 300,000 volumes it was tied with the Boston Public Library as the nation's largest library. It moved from the Capitol building to its new headquarters in 1897 with more than 840,000 volumes, 40 percent of which had been acquired through copyright deposit. 
A year before the library's relocation, the Joint Library Committee held 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  testified that the library should continue its expansion to become a true national library. Based on the hearings, Congress authorized a budget that allowed the library to more than double its staff, from 42 to 108 persons. Senators Justin Morrill of Vermont and Daniel W. Voorhees of Indiana were particularly helpful to gaining this support. The library also established new administrative units for all aspects of the collection. In its bill, Congress strengthened the role of Librarian of Congress: it became responsible to govern the library and make staff appointments. As with presidential Cabinet appointments, the Senate was required to approve presidential appointees to the position. 
1897–1939: Post-reorganization Edit
With this support and the 1897 reorganization, the Library of Congress began to grow and develop more rapidly. Spofford's successor John Russell Young 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. Two years after he took office, the library became the first in the United States to hold one million volumes.  Putnam focused his efforts to make 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. 
During Putnam's tenure, the library broadened the diversity of its acquisitions. In 1903, Putnam persuaded President Theodore Roosevelt to use executive order to transfer 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, Chinese, and Japanese works were also acquired. On one occasion, Congress initiated an acquisition: in 1929 Congressman Ross Collins (D-Mississippi) gained approval for the library to purchase Otto Vollbehr's collection of incunabula for $1.5 million. This collection included 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 to be used to solve problems, 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 donations and endowments by such prominent wealthy individuals as John D. Rockefeller, James B. Wilbur, and Archer M. Huntington. Gertrude Clarke Whittall donated five Stradivarius violins to the library. Elizabeth Sprague Coolidge's donations paid for a concert hall to be constructed within the Library of Congress building and an honorarium established for the Music Division to pay live performers for concerts. 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, although it used shelving expansions in 1910 and 1927. The library needed to expand into a new structure. Congress acquired nearby land in 1928 and approved construction of the Annex Building (later known as the John Adams Building) in 1930. Although delayed during the Depression years, it was completed in 1938 and opened to the public in 1939. 
1939–present: Modern history Edit
After Putnam retired in 1939, President Franklin D. Roosevelt appointed poet and writer Archibald MacLeish as his successor. Occupying the post from 1939 to 1944 during the height of World War II, MacLeish became the most widely known 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, and commissioning artist Ezra Winter to paint four themed murals for the room. He established a "democracy alcove" in the Main Reading Room of the Jefferson Building for important documents such as the Declaration of Independence, the Constitution, and The Federalist Papers. The Library of Congress assisted during the war effort, ranging from 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 when appointed as Assistant Secretary of State.
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. But he is best known for creating 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 Lawrence Quincy Mumford took over in 1953. During his tenure, lasting until 1974, Mumford directed the initiation of construction of the James Madison Memorial Building, the third Library of Congress building on Capitol Hill. Mumford directed the library during a period of increased educational spending by the government. The library was able to establish new acquisition centers abroad, including in Cairo and New Delhi. In 1967, the library began experimenting with book preservation techniques through a Preservation Office. This has developed as the largest library research and conservation effort in the United States.
During Mumford's administration, the last major public debate occurred about the Library of Congress's role as both a legislative library and a national library. Asked by Joint Library Committee chairman Senator Claiborne Pell (D-RI) to assess operations and make recommendations, Douglas Bryant of Harvard University Library proposed a number of institutional reforms. These included expansion of national activities and services and various organizational changes, all of which would emphasize the library's national role rather than its legislative role. Bryant suggested changing the name of the Library of Congress, a recommendation rebuked by Mumford as "unspeakable violence to tradition". The debate continued within the library community for some time. The Legislative Reorganization Act of 1970 renewed emphasis for the library on its legislative roles, requiring greater focus on research for Congress and congressional committees, and renaming the Legislative Reference Service as the Congressional Research Service. 
After Mumford retired in 1974, President Gerald Ford appointed historian Daniel J. Boorstin as librarian. Boorstin's first challenge was to manage the relocation of some sections to the new Madison Building, which took place between 1980 and 1982. With this accomplished, Boorstin focused 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 enhanced institutional and staff ties with scholars, authors, publishers, cultural leaders, and the business community. His activities changed the post of librarian of Congress so that by the time he retired in 1987, The New York Times called this office "perhaps the leading intellectual public position in the nation".
President Ronald Reagan nominated historian James H. Billington as the 13th librarian of Congress in 1987, and the U.S. Senate unanimously confirmed the appointment.  Under Billington's leadership, the library doubled the size of its analog collections from 85.5 million items in 1987 to more than 160 million items in 2014. At the same time, it established new programs and employed new technologies to "get the champagne out of the bottle". These included:
- American Memory created in 1990, which became The National Digital Library in 1994. It provides free access online to digitized American history and culture resources, including primary sources, with curatorial explanations to support use in K-12 education. 
- thomas.gov website launched in 1994 to provide free public access to U.S. federal legislative information with ongoing updates and congress.gov website to provide a state-of-the-art framework for both Congress and the public in 2012 
- The National Book Festival, founded in 2000 with First Lady Laura Bush, has attracted more than 1000 authors and a million guests to the National Mall and the Washington Convention Center to celebrate reading. With a major gift from David Rubenstein in 2013, the library established the Library of Congress Literacy Awards to recognize and support achievements in improving literacy in the U.S. and abroad 
- The Kluge Center, started with a grant of $60 million from John W. Kluge in 2000, this brings international scholars and researchers to use library resources and to interact with policymakers and the public. It hosts public lectures and scholarly events, provides endowed Kluge fellowships, and awards The Kluge Prize for the Study of Humanity (now worth $1.5 million), the first Nobel-level international prize for lifetime achievement in the humanities and social sciences (subjects not included in the Nobel awards) 
- Open World Leadership Center, established in 2000, by 2015 this program administered 23,000 professional exchanges for emerging post-Soviet leaders in Russia, Ukraine, and other successor states of the former USSR. Open World began as a Library of Congress project, and later was established as an independent agency in the legislative branch. 
- The Veterans History Project, congressionally mandated in 2000 to collect, preserve, and make accessible the personal accounts of American war veterans from WWI to the present day 
- The National Audio-Visual Conservation Center opened in 2007 at a 45-acre site in Culpeper, Virginia, established with a gift of more than $150 million by the Packard Humanities Institute, and $82.1 million in additional support from Congress.
Since 1988, the library has administered the National Film Preservation Board. Established by congressional mandate, it selects American films annually for preservation and inclusion in the new National Registry, a collection of American films. The library has made these available on the Internet for free streaming.  By 2015, the librarian had named 650 films to the registry.  The films in the collection date from the earliest to ones produced more than ten years ago they are selected from nominations submitted to the board.
- The Gershwin Prize for Popular Song, was launched in 2007 to honor the work of an artist whose career reflects lifetime achievement in song composition. Winners have included Paul Simon, Stevie Wonder, Paul McCartney, Burt Bacharach and Hal David, Carole King, Billy Joel, and Willie Nelson, as of 2015. The library also launched the Living Legend Awards in 2000 to honor artists, activists, filmmakers, and others who have contributed to America's diverse cultural, scientific, and social heritage
- The Fiction Prize (now the Library of Congress Prize for American Fiction) was started in 2008 to recognize distinguished lifetime achievement in the writing of fiction. 
- The World Digital Library, established in association with UNESCO and 181 partners in 81 countries in 2009, makes copies of professionally curated primary materials of the world's varied cultures freely available online in multiple languages. 
- National Jukebox, launched in 2011, provides streaming free online access to more than 10,000 out-of-print music and spoken word recordings. 
- BARD was started in 2013 it is a digital, talking books mobile app for Braille and Audio Reading Downloads, in partnership with the library's National Library Service for the blind and physically handicapped. It enables free downloads of audio and Braille books to mobile devices via the Apple App Store. 
During Billington's tenure, the library acquired General Lafayette's papers in 1996 from a castle at La Grange, France they had previously been inaccessible. It also acquired the only copy of the 1507 Waldseemüller world map ("America's birth certificate") in 2003 it is on permanent display in the library's Thomas Jefferson Building. Using privately raised funds, the Library of Congress has created a reconstruction of Thomas Jefferson's original library. This has been on permanent display in the Jefferson building since 2008. 
Under Billington, public spaces of the Jefferson Building were enlarged and technologically enhanced to serve as a national exhibition venue. It has hosted more than 100 exhibitions.  These included exhibits on the Vatican Library and the Bibliothèque Nationale de France, several on the Civil War and Lincoln, on African-American culture, on Religion and the founding of the American Republic, the Early Americas (the Kislak Collection became a permanent display), on the global celebration commemorating the 800th anniversary of the Magna Carta, and on early American printing, featuring the Rubenstein Bay Psalm Book. Onsite access to the Library of Congress has been increased. Billington gained an underground connection between the new U.S. Capitol Visitors Center and the library in 2008 in order to increase both congressional usage and public tours of the library's Thomas Jefferson Building. 
In 2001, the library began a mass deacidification program, in order to extend the lifespan of almost 4 million volumes and 12 million manuscript sheets. Since 2002, new collection storage modules at Fort Meade have preserved and made accessible more than 4 million items from the library's analog collections.
Billington established the Library Collections Security Oversight Committee in 1992 to improve protection of collections, and also the Library of Congress Congressional Caucus in 2008 to draw attention to the library's curators and collections. He created the library's first Young Readers Center in the Jefferson Building in 2009, and the first large-scale summer intern (Junior Fellows) program for university students in 1991.  Under Billington, the library sponsored the Gateway to Knowledge in 2010–2011, a mobile exhibition to 90 sites, covering all states east of the Mississippi, in a specially designed 18-wheel truck. This increased public access to library collections off-site, particularly for rural populations, and helped raise awareness of what was also available online. 
Billington raised more than half a billion dollars of private support to supplement Congressional appropriations for library collections, programs, and digital outreach. These private funds helped the library to continue its growth and outreach in the face of a 30% decrease in staffing, caused mainly by legislative appropriations cutbacks. He created the library's first development office for private fundraising in 1987. In 1990, he established the James Madison Council, the library's first national private sector donor-support group. In 1987, Billington also asked the GAO to conduct the first library-wide audit. He created the first Office of the Inspector General at the library to provide regular, independent reviews of library operations. This precedent has resulted in regular annual financial audits at the library it has received unmodified ("clean") opinions from 1995 onward. 
In April 2010, the library announced plans to archive all public communication on Twitter, including all communication since Twitter's launch in March 2006.  As of 2015 [update] , the Twitter archive remains unfinished. 
Before retiring in 2015, after 28 years of service, Billington had come "under pressure" as librarian of Congress.  This followed a Government Accountability Office (GAO) report that described a "work environment lacking central oversight" and faulted Billington for "ignoring repeated calls to hire a chief information officer, as required by law." 
When Billington announced his plans to retire in 2015, commentator George Weigel described the Library of Congress as "one of the last refuges in Washington of serious bipartisanship and calm, considered conversation," and "one of the world's greatest cultural centers." 
Carla Hayden was sworn in as the 14th librarian of Congress on September 14, 2016, the first woman and the first African American to hold the position.  
In 2017, the library announced the Librarian-in-Residence program, which aims to support the future generation of librarians by giving them the opportunity to gain work experience in five different areas of librarianship including: Acquisitions/Collection Development, Cataloging/Metadata, and Collection Preservation. 
On January 6, 2021, at 1:11 PM EST, the Library's Madison Building and the Cannon House Office Building were the first buildings in the Capitol Complex to be ordered to evacuate as rioters breached security perimeters before storming the Capitol building.    Carla Hayden clarified two days later that rioters did not breach any of Library's buildings or collections and all staff members were safely evacuated.

The Indian Removal Act was signed into law by President Andrew Jackson on May 28, 1830, authorizing the president to grant lands west of the Mississippi in exchange for Indian lands within existing state borders. A few tribes went peacefully, but many resisted the relocation policy. During the fall and winter of 1838 and 1839, the Cherokees were forcibly moved west by the United States government. Approximately 4,000 Cherokees died on this forced march, which became known as the "Trail of Tears."
11. It receives every public tweet you write.
The government isn’t just responsible for cataloging tweets coming out of the White House. In 2010, Twitter agreed to donate every public tweet in its archive to the Library of Congress. That amounts to several hundred million tweets a day. In addition to documenting the rise and fall of #dressgate and live tweets of The Walking Dead, the archive would also act as an invaluable data source for tracking language and societal trends. Unfortunately, that archive isn’t much closer to being completed than the day the deal was announced. The LOC has yet to develop a way to organize the information, and for the past seven years, unprocessed tweets have been have been stored out of sight on a server. There’s still no word on what the next step will be, but that might change with the newest Librarian of Congress. Unlike her predecessor, Carla Hayden is known for taking a digital-forward approach to librarianship.
