Link CONTENTdm data to bibliographic records in WorldCat

Learn how to link CONTENTdm data to bibliographic records in WorldCat using the single-item or serials workflow.

There are two workflows to link CONTENTdm data to bibliographic records in WorldCat:

  1. Single-item workflow
  2. Serials workflow

Preservation archive users have a one-time set-up and ingest steps.  See For preservation archive users.

Single-item workflow

  1. Add the items/objects to a CONTENTdm collection using either the Project Client or CONTENTdm Administration Web Add.
  2. Approve and index the collection.
  3. Set up a profile for the collection in the Digital Collection Gateway.
    • The Gateway will synchronize records from your CONTENTdm collection to create WorldCat records with viewonline links back to CONTENTdm. 
    • See Digital Collection Gateway for information on setting up a profile. 

Serials workflow

  1. Set up the OCLC number search in CONTENTdm. For each collection that contains content linked from WorldCat bibliographic records, set up the OCLC number metadata field:
    1. From collections tab in the CONTENTdm Administration, select fields.
    2. Select the desired collection from the Current collection dropdown menu and click change
    3. Under the Administrative Fields section, select edit on the OCLC number field.
      • Required: Ensure the Searchable option is set to Yes.
      • Recommended: Set the DC map to Identifier to benefit cross collection search.
      • Optional: Set the Hidden option to No. This will display the OCLC number in the item’s metadata view in the end-user interface.
    4. Click save changes and then Index the collection.
  2. Add search link in WorldCat.
  3. Add items to CONTENTdm.
    • If using the Project Client, add the noted OCLC number to the OCLC number metadata field of the item.
    • If using CONTENTdm Administration Web Add, add the item first, then edit the item in the Approval Queue where you can add the noted OCLC number.
  4. Approve and Index the collection.
