Established in 1800, the Library of Congress is the oldest cultural institution in the country. It houses the largest collection of photographs, maps, comic books and Bibles in the world. The shelving alone runs 826 miles, and that stores just some of its 170 million items, including 68 million manuscripts, 6.5 million pieces of music and more than 3.4 million recordings.

Hayden is both the first woman and the first African American to oversee the institution. She's also one of just three Librarians of Congress to have a professional background in the field of library sciences. (Other people to hold the post have been scholars, historians, lawyers and authors.)
