Please note: As of June 2018, Harvard recommends that all MARC bibliographic records be created in OCLC Connexion (please see Aligning the use of OCLC service offerings with Harvard Library organizational goals, approved by the Library Leadership Team in 2017). However, for those continuing to work in Alma, please note that these instructions apply to both systems.

• Full-level cataloging
  • Use # (blank) 
    • (previously Harvard used I or #)
  • PCC records will continue to require the 042 as applicable
• Full-level, material not examined (not used in regular cataloging workflows)
  • Use 1
• Less than full-level, material not examined (not used in regular cataloging workflows)
  • Use 2
• Abbreviated-level cataloging. A brief record that does not meet Minimal-level cataloging specifications. 
  
  • Use 3
• Core level
  • Do not use, obsolete.
• Partial (preliminary) level cataloging. Brief records that do not meet the requirements of Minimal-level cataloging specifications. 
  • Use 5 
    • (previously Harvard used 3 with a 500 note: Partial (preliminary) level record)
    • CONSER practice: LC full-level descriptive records lacking call numbers, subject headings, and related fields are coded 5 until these data elements have been assigned by LC. Harvard's CONSER catalogers may add 050 14 call numbers, subject headings, and other subject-related data elements, but leave the Encoding Level at 5 pending LC's edits.
      
• Minimal-level cataloging
  • Use 7 
    • (previously Harvard used K)
    • CONSER practice: Encoding level 7 is also used for otherwise full records containing non-series AAPs that lack supporting NACO records.
• Note on Pre-publication records
  

  • Please note that only CIP participants may use 8 for Pre-publication level.

  • CONSER practice: Harvard's CONSER catalogers may upgrade Pre-publication records created by the US ISSN Center according to established procedures, but designated staff in Serials Cataloging must then report these changes to the Center: Serials Cataloging - Instructions for ISSN Requests /wiki/spaces/ITSworkflows/pages/54822637
• Note on batch process records
  
  • M is automatically assigned to batch-loaded records; it cannot/should not be manually assigned by catalogers. Staff editing M-level records should adjust the encoding level as appropriate. 
  • OCLC is actively working on a process to evaluate OCLC records with the aim of assigning accurate coding to records and eliminating the "M" encoding level.

...

Encoding levels may still be updated when enhancing a record. Please follow the table below for guidance. Please note that copy cataloging practice may vary slightly by unit, and changes to encoding level should only be made if it aligns with your unit's practice and after consultation with your manager. . In line with current practice, if no other changes are being made to the bibliographic record, there is no requirement or recommendation to change the encoding level.

When modifying an encoding level, all cataloging “full” level users may change or upgrade as follows:
