Why am I missing records?
Some titles might not meet the requirements for record output
In order to receive a record for a knowledge base title, titles must meet specific requirements.
Format, coverage value, and title URL requirements
Titles must:
- Have an OCLC number and have a URL/856 and be of a readable format and coverage (i.e., journal [fulltext, print], ebook, and so forth), or
- Have an OCLC number and have a coverage value of other or print (but lack a URL/856)
Reasons for missing OCLC numbers
Titles must have an OCLC number (OCN). A title might be missing an OCLC number if:
- No record exists for the item in WorldCat
- A record exists but because of the complexities of cataloging electronic items, it is not classified as an electronic resource in a way that corresponds to the knowledge base’s matching process
To report missing OCNs, see Report errant OCLC numbers.
A title is in multiple collections
Titles are often available through more than one provider. If you have a title in multiple knowledge base collections, Collection Manager will deliver a single record for the knowledge base title and the record will have multiple URLs.
If all of your records are delivered in one file and you hold a title in several knowledge base collections, you will get one record for the title. To have records output in a separate collection, see Collection-level settings in knowledge base collections, Delivery File Output.
