Best practices for local extensions (local fields) in NZ-linked records

Local extensions are local fields that can be added to NZ-linked bibliographic records. These fields are marked by a house icon in Alma.  

 

 Specifically, you can enter local information in the MARC 21 77X/78X, 09X, 59X, 69X, and 9XX fields. 

 The fields only appear to your specific Institution Zone; they do not appear when other institutions are viewing the NZ record.  

 Local extensions can be added to NZ-linked records either in the Metadata Editor, or in batch via a normalization rule, import profile, or MARCedit. 

 

 Adding local extensions in the Metadata Editor 

 After opening an NZ-linked record in the Metadata Editor, choose Editing actions > Add local extension to enter a local extension in the bibliographic record. 

 Although not visible in the Metadata Editor, please note that the $$9 local subfield is automatically created and stored in the cached record. This subfield will appear in the local extension when exporting the MARC record from Alma. 

 A local extension should NOT be added to a record using the  Editing Actions > Add field function, and then adding a $$9 local to the field. This will result in a false "local" field that is actually viewable by all institutions. 

 

 Adding local extensions via normalization rule / import profile / MARCedit 

 Local extensions can be added in batch to NZ-linked records using a normalization rule, an import profile, or MARCedit as long as it follows these guidelines 

 

 Can only be a 77X/78X, 09X, 59X, 69X, or 9XX field 

 Must add a $$9 local (although not visible in Alma, the $$9 local subfield is stored in the cached record) 

 

 Non-local fields (those without a $$9 local) CANNOT be added to NZ bibliographic records in batch in an Institution Zone by any method
