To further OCLC’s announced move to using standard MARC encoding levels instead of the OCLC alphabetic encoding levels, OCLC will begin converting Encoding Level K records in WorldCat in January to encoding levels blank, 7, or 3 as appropriate according to determinations of record fullness.  OCLC has been testing conversion criteria for a number of months.  The conversion effort of the 25.9 million K level records currently in WorldCat will be spread out over a number of months in 2021.  This effort will provide us insight into the larger conversion effort of encoding level M records in the future.

For further information on the rationale behind this change, please see the June 2020 Virtual AskQC Office hours presentation slides, WebEx recordings and Q&A, all available on the Previous AskQC Office Hours page.<https://help.oclc.org/WorldCat/Metadata_Quality/AskQC/Previous_AskQC_office_hours>
