WASHINGTON (AP) -- The nation is about to get a new chief librarian.
Carla Hayden will be sworn in Wednesday as the 14th librarian of Congress. Chief Justice John Roberts will administer the oath of office during the ceremony at the library's Great Hall.
Hayden will be the first woman and the first African-American to lead the national library since its inception in 1800. She's the longtime CEO of the library system in Baltimore. She's also just the third professional librarian to get the job.
President Barack Obama signed a law last year establishing a 10-year term for the librarian of Congress. It was previously considered a lifetime appointment. Hayden's predecessor, James Billington, held the job for 28 years and was criticized for not keeping up with changes in technology.
