OCLC will be performing system maintenance on Tuesday, May 15, 2007. OCLC MARC Subscription files normally available between 5 a.m. and 7 a.m. Eastern Time will be delayed on that day. This affects files retrieved by users using either FTP (EDX) or Product Services Web, including those files for CatExpress members who have chosen the next-day record delivery option. OCLC will provide an update once the files have been made available and apologizes for any inconvenience this may cause member libraries.
