Records may be merged in the web interface when they are suggested by the system. Duplicate records that are identified by other means can be merged by the PCC ISNI Quality Team in the WinIBW client.
Resolving possible matches
...
The merge program acts on the basis of field 77A in records. It is run on the database twice a day at 11:00 and 16:00 GMT.
Multiple matches
If the system identifies multiple possible matches, they will be shown together. Each of the possible matches must be resolved as either "Equal" or "Unequal" before the records can be merged. In the example below, four matches have been marked "unequal" and one has been marked "equal," but there is still one shown as a "possible match." The record showing the possible merges won't be merged until all of them are resolved. (However, in this example, the first and third possible merges reference the same PPN (12022884X). This prevents the user from marking the third one as "equal." The situation can only be resolved by deleting one of the 77A fields in the WinIBW client. This situation is rare.)
Matches not suggested by the system
If you locate a duplicate that was not flagged by the system, you can add a general note with the information ; a general note to any record in ISNI triggers an email query to the it can be reported to the PCC ISNI Quality Team for merging.
These For example, these 2 records below (both assigned) are duplicate, duplicates; several bibliographies confirm that the two names represent the same person, but they are not flagged by the ISNI system.
In any of the two records you can add a general note to notify the Quality Team about the situation and request a merge:
