In the event of a Government shutdown, the Library of Congress will be temporarily closed beginning Tuesday, October 1, until further notice. During this period, the Library will be unable to respond to any communications received. Classification Web and Cataloger's Desktop will continue to be available, but should any technical difficulties arise during the closure no customer service or technical support can be provided. We will be unable to process orders for print products. We apologize for the inconvenience.
MARC Distribution Services (MDS) will continue to be available, but subscribers can expect fewer records than normal on the daily and weekly distribution files. Depending on the length of the shutdown, null files or a disruption in service might be possible. Should any technical difficulties arise during the closure no customer service or technical support can be provided. We apologize for the inconvenience.* * * * *
