Content designator history:

Field 088 - Document Shelving Number (CODOC) [redefined, 1997] [CAN/MARC only]: Both indicator positions were undefined. The subfield codes were: $a (Document Shelving Number (CODOC)) and $6 (Linkage). CODOC numbers are now recorded in field 084 (Other Classification Number).

Prior to 2015, series report numbers were included in fields 490/830, not in field 088.
