Page Comparison

856 fields are loaded into the bib record.

If the target record is in field group v LOCAL INFO and includes any of these strings:

• |2pika

• |2vufind

• |2image

• |2Pika

• |2VuFind

• |2Image

then the field is protected. No incoming 856 field with “|2pika” will load in that case.

All other 856 fields are not protected. They will be overlaid from the incoming record. If there is no 856 in the incoming record, they will be deleted from the target record.

Code:

856||+|0|0|b|v|0|y|N|0|%map="m2bmap.art" 
856||+|0|0|b|y|0|y|N|0|%map="m2bmap.not"
