Modify a collection to select your subset of titles

Follow the instructions to download a KBART-formatted spreadsheet of title data, modify the data to match your subscription, and upload the collection.

About adding knowledge base collections

To see the collections in the global knowledge base, browse the collections available in the WorldCat knowledge base (updated monthly). Alternatively, perform a search in Collection Manager to return all available collections. Deselect My Selected Collections and click Search.

When to select a knowledge base collection in full (the entire collection)

Select a knowledge base collection in full if it is available in the global WorldCat knowledge base and the entirety of the collection titles match your subscription.

When to modify a collection to select your subset of titles

Modify a knowledge base collection if it is available in the global WorldCat knowledge base and your library subscribes to a subset of the titles in the collection.

If your library subscribes to a subset of the titles in a collection, you can modify the collection. You have the following options for selecting the collection:

  • Select the titles individually via the Titles drop-down in the collection.
  • Modify the title selections, coverage and other title data to match your library-specific holdings one title at a time within the interface or in bulk by modifying the KBART-formatted spreadsheet and uploading your modified file.
When to create a knowledge base collection

If a collection your library needs is not already represented in the global WorldCat knowledge base data, create a knowledge base collection in Collection Manager using the steps on this page. For example, if your library has a niche or unique electronic collection, you can create the collection.

Find instructions to create knowledge base collections for print serials or represent databases:

For some collections, OCLC and your provider can automatically add and maintain your library-specific collection data. See Providers and contacts for automatic collection loading for more information.

 Caution: Once you have requested to have your collections selected automatically, do not add, delete, or update any of the titles within the collection. If there is an issue with the titles selected or missing from your collection, please contact OCLC Support with examples.  

For other methods to add knowledge base collections, see Choose a method to add or create a knowledge base collection.

If you choose the "Available titles in collection" scope, your file will contain the complete title data from the global knowledge base collection and can be used to select the desired titles for your library's local holdings. Choose this option if:
      • You want to download title data for all of the titles available in the collection
    • My Selected Titles
      If you have selected titles in the collection, you will see the scope "My Selected Titles". Selecting this scope means your file will contain only your selected and/or modified titles. Choose this option if:

  2. Click Download.
  3. The file you download will be a .txt file. To edit the file, open it in Microsoft Excel or in an equivalent spreadsheet editing application.

    • Date columns
    • ISSN or ISBN (print_identifier)
    • eISSN or eISBN (online_identifier)
