Best Practice For 33x and 007 Fields in Alma

33x

• Bibliographic record

  • The 33x should reflect all of the formats of the manifestation described in the bibliographic record
  • Bibliographic record should NOT have 33x fields for NET or other holdings with different formats

• Holdings record

  • For all holdings, regardless of format 

    • Do not copy 33x into holdings

007

NB:  Not every record needs the 007 field, but for those records needing and 007 field, the practice has changed

• Bibliographic record

  • 007 will NOT be stripped from Harvard’s bibliographic records upon import to Alma
  • 007 (if necessary) should reflect only the format(s) of the manifestation described in the bibliographic record
  • 007 fields should not be added to the bibliographic record to represent holdings for formats not described in the bibliographic record.

• Holdings record

  • When the format(s) described in the bibliographic record matches the format(s) of the holdings record(s)

    • Do not copy 007 field to holdings record(s)

  • When the format(s) represented by the holdings record(s) is/are not reflected in the bibliographic record

    • Create appropriate 007 field(s) in each holdings record

Legacy records

• There is no need to remove extraneous 33x or 007 fields from legacy holdings records, although it does no harm to do so.
