Why is a knowledge base link not appearing on a title in WorldCat Discovery?
Applies to
- WorldCat Discovery
- WorldShare Collection Manager
Answer
To ensure knowledge base links surface in WorldCat Discovery, follow these steps:
Confirm Title Selection and Set OCLC Number in Collection Manager
- 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.
Matching Discovery article records to parent titles in WorldShare Collection Manager
- Locate the journal 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.
Understand Publication Types and Coverage Depths
Surface Links for Article Records
- 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.
Surface Links for Monograph Title Records
- 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:
- OCLC Number (OCN)
- ISSN/ISBN
- Title (with more than three matching words, excluding articles like "a" or "the")
Avoid Duplicate Links
- 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.
