MARC 991 TIND Suppressed
The MARC 991 field is a local field used by the TIND ILS. It controls whether a record that would normally display in the public catalog is suppressed from public view.
It is similar to MARC 980 (TIND's "Collection" field) and MARC 983 (source of the "Item access" facet in the catalog), both of which also depend on Folger staff entering specific text.
Adding 991__ $$aSUPPRESSED
to a record that would normally display to the public suppresses it from public view. The record will still appear in searches and results list for Collections staff (with a red "Restricted" flag in the left margin indicating that access to the record is restricted to authorized staff).
