OCLC has been notified by the Library of Congress that a major upgrade of their Voyager system will take place beginning on Friday, May 9, 2008 and continuing through Sunday, May 18, 2008.
During that time, OCLC will not receive the various daily and weekly files of bibliographic records and subject authority records that are normally loaded on receipt. Distribution of these files is expected to resume on Monday, May 19, and OCLC will resume loading files at that point.
During the upgrade, the Library of Congress will continue to receive the NACO contribution files which OCLC sends each day but those files will not be processed until May 19. As a result, NACO participants can expect new and updated authority records which they have contributed to remain locked for longer than normal periods of time.
