Advisory: Possible Federal Shutdown
In the event of a temporary shutdown of the federal government, beginning Tuesday, October 1, all Library of Congress buildings will close to the public and researchers. All public events will be cancelled and web sites will be inaccessible.
In addition, the National Archives and Records Administration contingency plan is available as a PDF download at http://www.archives.gov/contingency-plan/contingency-plan.pdf says (in part):
Federal Records Center shares occupancy with archival or other appropriated operations, the portion of the facility that is used exclusively for appropriated activities will be closed to employees and the public and will be secured. . . .I suspect that many other government services, including many used by genealogists, will also close.
NARA public websites will remain online, but will contain a banner that indicates that the National Archives is closed. The website may be updated to indicate that NARA events have been cancelled, depending on the duration of the shutdown.
