Will local notes be lost when the bibliographic record in the NZ is overlaid?
Answer
Local notes will not be lost when the NZ bibliographic record is overlaid because they are stored in the Institution Zone, on the local copy linked to the NZ record.
Local fields are added into a IZ bibliographic record using Edit>Add local field (Ctrl+L). Alma creates a field with an invisible subfield $9 containing the string "local" (all lower case).This subfield $9 is used by Alma to mark fields as local. Although this subfield $9 is not displayed in Alma (the local field building icon is displayed instead), it is present in local fields when bib records are exported.
