WorldCat Metadata API Currently Unavailable

We are experiencing a problem with the WorldCat Metadata API web service and it is temporarily unavailable. Our investigation so far indicates that the problem is related to user authentication. We are analyzing options for resolving this as quickly as possible and will provide an update to the Developer Network later today. We apologize for any inconvenience this may cause.  

Please Contact Us if you have any questions.
