Library of Congress

With Congress unable to work out a deal to keep America's doors open, many government Web sites are either unavailable or sitting idle, awaiting funding.

For example, the Library of Congress archives, a treasure trove of information, photos, and historical documents recounting US history, are unavailable Tuesday.

Click on for a sampling of more government sites (and Twitter feeds) gone dark or in a suspended state.

Correction at 5:05 a.m. October 2: The final slide has been removed. The USAjobs.gov site is up and has not been affected by the federal shutdown.
