The Smithsonian Insitution's National Museum of American History, Kenneth E. Behring Center, which houses the Dibner Library, closed to the public on September 5, 2006, for a major renovation project that is scheduled to last two years. While this has affected access to our facilities, we will nonetheless make every effort to accommodate researchers who need access to our materials. Should your research require use of the collections, please contact us.

Please bear in mind that the new arrangements will require advanced notice, and that appointments may not be immediately available. We apreciate your patience and flexibility as we adjust to these circumstances.
