Local Network Zone MARC Fields
There are several MARC fields specific to the Washington Research Library Consortium. They often (but not always) have subfields designating that they are local WRLC fields.
Field Indicators Value Additional fields Further Documentation Record Type
| Field | Indicators | Value | Additional Subfields | Further Documentation | Record Type |

| 650 / 651 | _ 0 | Replacement WRLC subject headings | NONE ; Because these headings are categorized as local Library of Congress Subject Headings by Alma, they DO NOT have additional subfields | NZ records | |
| 650 | _ 7 | Supplemental WRLC subject headings | $$2 local $$5 CAO | NZ records | |
| 690 | _ 7 | Replacement AND Supplemental WRLC subject headings. Because we cannot add local LCSH to CZ linked records, all local WRLC subject headings are added to CZ records as supplemental headings in this specific field. | $$5 CAO $$9 local |
