Introduction to the Library of Congress
The Library of Congress is the national library of the United States and the largest library in the world. Located in Washington, D.C., it is housed in three buildings on Capitol Hill and serves as the research library for the United States Congress. With more than 170 million items in its collections, the library stands as a symbol of public access to knowledge and democratic values.
Foundation and Growth
The Library of Congress was founded in 1800, initially to serve the legislative needs of Congress. In 1815, after the original collection was destroyed by British troops during the War of 1812, former President Thomas Jefferson sold his personal library to Congress. This collection of over 6,000 books became the foundation of the Library’s modern holdings. Since then, the institution has expanded its mission and scope dramatically.
Vast Collections
The Library’s collections span an extraordinary range of formats, subjects, and languages. They include:
- More than 38 million cataloged books and other printed materials in over 470 languages
- Over 70 million manuscripts, including personal papers of American presidents and historical figures
- 5.6 million maps, 14 million photographs, 8.2 million pieces of sheet music, and 3.6 million sound recordings
Among its treasures are the Gutenberg Bible, early drafts of the U.S. Declaration of Independence, and recordings from America’s musical and oral history.
Access and Digital Innovation
The Library of Congress is open to the public and offers a wide array of exhibitions, reading rooms, and research services. It also has a robust digital presence, providing free access to millions of digitized materials through its website. The Chronicling America project, the American Memory collection, and the National Jukebox are just a few examples of how the Library shares knowledge with the world.
Support for Research and Education
As a leading center for research and education, the Library offers grants, fellowships, teacher resources, and public programs. It supports innovation in library science and works with institutions across the country and around the globe to promote literacy and preserve cultural heritage.
National Symbol of Knowledge
The Library of Congress represents the ideals of openness, scholarship, and preservation. It is not just a library—it is a symbol of America's intellectual vitality and a vital resource for citizens, educators, and researchers. By continuing to collect, preserve, and share knowledge, it fulfills its mission to inform the American people and inspire future generations.
