From IMLS:
On February 24, 2011, the Honorable Stephen G. Breyer, Associate Justice of the United States Supreme Court, administered a ceremonial oath of office to Susan H. Hildreth, the new Director of the federal Institute of Museum and Library Services before a gathering of library and museum leaders, federal and state officials, national service organizations and congressional staff. Hildreth noted, “I am so pleased and honored to have this appointment. I want to make sure we use the power of libraries and museums to enrich the lives of our citizens. We must ensure that libraries and museums continue to re-invent themselves to be powerful forces for the civic life in our communities.”

Hildreth is the fourth Director of the Institute of Museum and Library Services. She began her career as a branch librarian at the Edison Township Library in New Jersey. She has held several key leadership positions including president of the Public Library Association. Prior to her appointment at IMLS, Susan Hildreth was the city librarian in Seattle for two years. Hildreth also served for five years as California’s state librarian. Previously, Hildreth was at the San Francisco Public Library, where she served as deputy director and then city librarian.

IMLS Directors are appointed by the President and confirmed by the Senate for four-year terms. The position alternates between library and museum professionals. Her nomination to her new post was confirmed by the US Senate by unanimous consent on December 22, 2010.
