1. Create a non-MARC numeric search key collection

Learn how to create a non-MARC numeric search key collection in WorldShare Collection Manager.

Create a non-MARC numeric search key collection to have OCLC use a simple list of data to match against WorldCat records for setting or canceling holdings.

 Caution: When entering text into text fields (e.g., Comment, Description, etc.):

  • Do not add new lines. All text needs to be in one paragraph.
  • Do not copy and paste text from Microsoft Word, email, a web browser, or other sources. Pasted text can contain hidden formatting codes.


  • You cannot delete a collection once it has been saved and/or submitted.
  • If you have questions while creating your collection, you can:

Create the collection

  1. Navigate to the WorldShare interface > Metadata tab > Collection Manager.
  2. Click Create a Collection.
  3. Select Data Sync Collection from the Collection Type drop-down list.
  4. Select Bibliographic or Delete WorldCat Holdings from the Data Sync Type drop-down list.
     Note: If you have already created a WorldCat Data Synchronization collection with the secondary collection type, the following warning appears:
    An existing WorldCat Data Synchronization collection of this same type already exists. We recommend editing this existing collection; however, you can create a secondary collection type of the same type.
    Generally, you will configure one collection for each type of data to be sent, making it easier to manage the process and maintain up-to-date holdings in WorldCat.
  5. Click Create. The accordions for this collection appear.

Complete the Properties accordion

The Properties accordion must be completed before you can save your progress when creating a collection.

  1. Enter a Collection Name for your collection.

  4. Select Yes for Numeric Search Keys for Holdings Maintenance Only.
     Note: You must send a .CSV file, encoded as UTF-8. Please see data requirements.
  5. (Optional). Enter a Description for the collection. The description field should be used anytime there is an exception or special consideration with your collection (e.g., setting up a collection to use OCLC number matching only). The exception or special condition should also be added as a comment in the Comments accordion.

Complete the Comments accordion

The comments accordion allows you to communicate with the database specialist assigned to your data sync collection. It appears after you save your collection for the first time. Database specialists can also communicate with you about your collection.
