by TeachThought Staff

The recent dismissal of Dr. Carla Hayden, the 14th Librarian of Congress, has brought renewed attention to the Library of Congress—but what exactly is the Library of Congress, and why does it matter?

The Librarian of Congress leads the institution and is appointed to a 10-year term. Hayden, who held the role until May 2025, was a notable figure in LoC history. She was the first woman and the first African American to lead the institution, and her tenure focused on:

• Expanding digital access to collections.
• Increasing public outreach and education.
• Promoting equity and inclusion in library services.

Her abrupt removal by the Trump administration raised concerns among educators, librarians, and civic advocates about the independence of institutions like the Library of Congress.
