Geeze — I just logged into the Library of Congress’s Classification Net, and this message was displayed:
As of Saturday, April 9, the Library of Congress will be temporarily closed until further notice due to the general U.S. federal agency shutdown. During this period, the Library will not be responding to any communications received. Classification Web will continue to be available but no customer service or technical support will be provided.
I guess when the U.S. government is threatened with complete and total shutdown, it can effect even me, a lowly librarian up in Canada, trying to look up some call numbers. Luckily, the government managed to avoid such a shutdown — good job, guys!
