Pourquoi manque-t-il des notices?

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:

  • être dotés d'un numéro OCLC ainsi que d'une URL/d'un code 856 et avoir un format et une valeur de couverture lisibles (par exemple, revue [texte intégral, impression] ou livre électronique) ou
  • 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:

  • Il n'existe pas de notice correspondant au titre dans WorldCat.
  • Une notice connexe est disponible, mais, du fait de la difficulté à cataloguer les éléments électroniques, elle n'a pas été classée en tant que ressource électronique soumise au processus de mise en correspondance de la base de connaissances.

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.
