OCLC will be conducting a maintenance install this Sunday, November 14th, which should be completed between 7-11 am. WorldCat.org and WorldCat Local will be unavailable during this time. This is to move the WorldCat database to a new storage device.
This means that the Search functions for Catalogue and Catalogue Plus will be unavailable during this time. However, you will still be able to renew and check your loans and use the old catalogue interface.
