What is the Library of Congress?

The Library of Congress, established in 1800, stands as the United States’ national library and the largest library in the world. Serving as the primary research arm for Congress, it has evolved into a vast repository of knowledge housing more than 173 million items, including books, manuscripts, films, photographs, maps, and digital materials. Its iconic main building, the Thomas Jefferson Building, along with the John Adams and James Madison Buildings, form an impressive complex on Capitol Hill in Washington, D.C.

Under the leadership of the Librarian of Congress, a presidential appointee confirmed by the Senate, the institution fulfills several critical functions beyond congressional support. It houses the U.S. Copyright Office, which registers and protects intellectual property rights, and preserves historically significant documents and cultural materials vital to American heritage. The Library also provides extensive reference services and administers specialized programs like the National Library Service for the Blind and Print Disabled.

While primarily serving congressional needs, the Library of Congress has expanded its mission to become a global resource for researchers, scholars, and the general public. Its reading rooms and exhibitions offer direct access to its vast collections, while digital initiatives have increasingly made these treasures available online. Through these efforts, the Library continues its foundational purpose of preserving America’s cultural heritage and intellectual achievements while adapting to serve as an accessible knowledge center for future generations.

TL;DR: The Library of Congress is America’s giant, fancy book hoarder that helps Congress do its homework, protects copyrights, and lets everyone browse a mountain of knowledge—even online.

Carla Hayden

Librarian of Congress – Library of Congress
Fired on May 8, 2025

President Donald Trump fired Carla Hayden, the Librarian of Congress, on May 8, 2025, with her termination email stating the dismissal was “effective immediately.” Hayden, who was the first woman and first African American to hold the position, was removed. Her term was set to expire in 2026.

White House Press Secretary Karoline Leavitt defended the decision, citing “concerning things” Hayden had allegedly done regarding DEI initiatives and “inappropriate books” for children. The firing appears to be part of broader changes to cultural institutions under the Trump administration, with some supporters, like America First Foundation president Tom Jones, having previously called for Hayden’s removal to “return an America First agenda to the nation’s intellectual property regulation.”
