Temporary ISBN display changes for FS, WCRS, and WCAS
The ISBN display will temporarily change in the WorldCat and Group Catalog databases as seen in FirstSearch, WorldCat Resource Sharing, and WorldCat Collection Analysis Services. ISBN searches will continue to cover all variations of ISBNs, but the display of the record may show only one version of the ISBN for several months while OCLC adds the needed information into records.
Any 10-digit ISBN now has an equally unique corresponding 13-digit ISBN beginning with the numbers 978. When publishers’ 10-digit ISBN run is finished, new ISBNs will 979. ISBNs starting with 979 will have no corresponding 10-digit ISBNs.
Through February 17, 2007 any record in WorldCat and Group Catalogs with a 10-digit ISBN or a 13-digit ISBN starting with 978 will display both ISBNs. Starting February 18, both ISBNs will remain searchable, but only one ISBN will display while OCLC starts to insert the corresponding ISBN into the stored data of all records. It will take several months for every 10-digit ISBN to display with both it’s paired 13-digit ISBNs. In the first few days, the newest records may have the 13-digit ISBN starting with 978 but not the 10 digit ISBN displaying. These records will be converted first, so that they will soon show both ISBNs. Then over the next several months the rest of the records in WorldCat and Group Catalogs will start to display both ISBNs also.
Throughout this time all ISBNs will remain searchable, even if both ISBNs are not visible in the record display.
