Step 2.3: Field Updates & Deletes

Rda2-1.png

Changes to the MARC21 communications format have made many fields obsolete. If one field has been replaced by another, the change is shown in the Tag Updates table in this section.

If the field has been made obsolete without being replaced, the field is simply deleted from the bibliographic record. Fields that are deleted as part of MARS 2.0 are listed in the Field Deletes List in this section.

Field Updates Table

Fields and subfields converted by MARS 2.0.
(‘x’ represents any 2nd indicator value, ‘#’ represents a blank 2nd indicator value):

From To From To
023 024 [8#] 315 310
211 [0x] 246 [2#] 350$a $b 037$c (CF,CR)
211 [1x] 246 [3#] 350$a 020$c or 037$c* (BK,VM,MU)
212 [0x] 246 [2#] 503 500
212 [1x] 246 [3#] 507 255 (MP)
212 [2x] 246 [3#] 512 500
212 [3x] 246 [3#] 523 500
214 [0x] 246 [2#] 527 500
214 [1x] 246 [3#] 537 500
265 $a 037 $b 543 583
308 $a & b 300 $a 570 500
308 $c, $d & f 300 $b 755 655
308 $e 300 $c 840 830

  • MARS Processing will first attempt to convert 350$a to 020$c, but if unable to do so based on multiple or no ISBN, or multiple 350$a then it will fall back to 037$c.
