"Held by" statement for titles under embargo

In WorldCat Discovery, when search results contain an article or item from a knowledge base title that has an embargo period or moving wall of coverage, links will correctly display or not display in alliance with the coverage information in your knowledge base title. However, the "Held by" statement uses different logic. It is a known issue that the statement might appear for items not yet available, including those that correctly do not surface links.
Similarly, if a journal title in your knowledge base has multiple coverage ranges with gaps in coverage, articles that surface in Discovery search results that fall within the gap of coverage will have a "Held by" statement.  

Note: For proper link display, your settings must be correct:

In WorldShare Collection Manager, Institution Settings > Coverage > Use Coverage to Determine Holdings should be set to Yes In OCLC Service Configuration, under Default Databases and Licensed Content, Treat as held should be disabled for your selections

The Date format on articles is impacting being "held by" and the article links

When determining whether an item is held by the library or when creating and displaying links to publishers’ websites, the WorldCat knowledge base is not properly handling article dates that include a season (e.g., Spring 2022) or range of months (e.g., Jan/Feb 2022).
