Representative record on grouped search results
In WorldCat Discovery if the search results are set to Group editions and formats or Hide duplicates, a representative record is determined for the group. Edition grouping brings records together that have the same:
- WorkID (title, author, format)
- Language of publication
- Sub-format (if applicable)
- Year of publication
- Publisher (first entry)
Variant records group records for the same edition which may have different languages of cataloging or may be duplicate records which have not yet been resolved.

- 2nd priority: Most recent
- 3rd priority: Language of cataloging matched from language of the user interface
- The language setting for the user's browser or the language selected in the WorldCat Discovery interface is used to infer preferred language.

The flat view shows all records in the search results and does not group by work, edition, duplicate, or language of cataloging. See
Representative record in Explore Editions and Formats
WorldCat Discovery will display results in this section grouped by a user’s search preference.
One representative record is displayed for each edition when search filters are set as below:
- Group related editions is enabled.
- Group related editions is disabled and Hide duplicates is enabled.
If holdings are set on more than one record in an edition grouping, the user’s language of preference will be used to determine which edition record displays.
If the user has set their search filters to disable Group editions and formats and disable Hide duplicates, the Explore Editions and Formats will display a flat view of every record in the work set.
View all availability from the edition grouping
Enable the display of availability from the grouped editions when holdings have been set on records for different languages of cataloging for a given edition. Availability is configured to display from the OCLC number by default. To enable availability display from the edition grouping, see Search Settings.
When enabled, the representative record will display all the availability information from the records in the grouping.
Note: This configuration will work best for WMS institutions that have Local Holdings Records in WorldCat. Non-WMS institutions can enable this new setting; however, It is recommended that you monitor availability performance and disable this configuration if the system slows or appears unable to support additional availability calls.
For example, additional availability information for a record of a different language of cataloging than the language of cataloging on the representative record will display.
Level 1 edition availability:
Additionally, availability will also display for group availability at level two holdings.
