Why is a knowledge base link not appearing on a title in WorldCat Discovery?

To make sure your resources are properly linked between WorldShare Collection Manager and WorldCat Discovery, follow these steps:

Ensure you have selected the correct monograph or journal title in Collection Manager.
- Use the OCLC number or article ISSN from the WorldCat Discovery record to perform a title search in WorldShare Collection Manager.
Verify that the title is matched to the WorldCat Discovery record using the OCLC number or ISSN.
Add the Discovery record's OCLC number as a grouped OCN to the title in WorldShare Collection Manager.
- Note: This method is not applicable for article records. The 001 field of an article is considered a unique identifier and not an OCLC number that can be searched in WorldShare.

Locate the jounal or representative record for the article record.
- Use the ISSN from the Discovery article record to perform an n2:ISSN NUMBER search in Discovery.
- Select the first record in the search results, which is the article's parent or representative record.
- Use the OCLC number from the representative record for title search, or as override OCN on a title in WorldShare Collection Manager.
Confirm that the Discovery article record's date falls within the WorldShare Collection Manager title's specified coverage date range.

Only specific publication types and coverage depths will display links in WorldCat Discovery. For more details, refer to the section on Publication Types and Coverage Depths that Surface Links.

Matching Criteria: WorldCat Discovery uses the ISSN or the title (with more than three matching words, excluding articles like "a" or "the") to find a match in the knowledge base.
Metadata Requirement: If the ISSN or title is not present in the article metadata, a knowledge base link will not appear.

Matching Criteria: For monograph titles such as eBooks, eVideos, or eAudios, WorldCat Discovery uses the following order of preference to find a match in the knowledge base:
1. OCLC Number (OCN)
2. ISSN/ISBN
3. Title (with more than three matching words, excluding articles like "a" or "the")

If a title is selected in multiple collections from the same provider, and those titles have identical URLs and coverage, WorldCat Discovery will de-duplicate the entries. Only one link will be displayed on the item record to avoid redundancy.
