Report errant knowledge base links (Fundamentals)

See how to report broken links to OCLC and how to troubleshoot missing and errant links.

 Note: If you are a WMS library or using full WorldShare Collection Manager, see Report errant knowledge base links.

Report a broken link to OCLC

Contact OCLC Support with the following information, if you have it:

  • Your institution’s name
  • OCLC symbol or Registry ID
  • URL to the item
  • OCLC number of the item, if available
  • Collection ID of the collection from which the item appears
  • (Optional) Proxy credentials to access your resources*

*If you are unable to provide test proxy credentials, OCLC might need to conduct a screen-sharing session with your library to troubleshoot.

Report a broken link to library staff

If you enable the "Report a broken link" form so that it appears in your WorldCat Discovery interface and A to Z list, both patrons and library staff can report broken links to your library. See Enable "Report a broken link" and receive emails for more information.

 Caution: OCLC does not receive the emails sent to your library.

Troubleshoot missing or errant links

Verify that full-text links are enabled

Enable full-text links in OCLC Service Configuration:

  1. Sign in to OCLC Service Configuration.
  2. Navigate to the  WorldCat Discovery and WorldCat Local > Full Text and Open Access Links.
  3. Check Links from the WorldCat knowledge base to full text content. This will automatically select the settings for links to appear on the detailed record and on the brief record on the search results page. If for some reason you do not want links in search results, adjust the Search Results setting.

Check your settings

Verify settings in the WorldShare interface, Metadata > Collection Manager Fundamentals > Institution Settings.

Proxy settings

Review the Proxy settings checklist. Note that if the title with the errant link is from an open access collection, you might need to disable the proxy setting within the collection's settings in Collection Manager Fundamentals.

Check your proxy settings for off-campus access

Proxy Type

  1. Navigate to Institution Settings > Proxy and authentication > Proxy.
  2. Select Proxy:
    • None (default)
    • EZproxy
    • III WAM Proxy

Base URL

  • EZproxy users:
    • Enter your Base URL. Example of a EZproxy base URL:
  • III WAM Proxy users:
    • Enter the Hostname. Example of a III WAM Proxy hostname:

 Caution: Do not include a space after the Base URL.

Username and Password

(Optional) Enter your Username and Password. Providing username and password information is used by OCLC for de-bugging purposes only.

Provider settings

See if a provider-specific identifier is needed for links to resolve
Find information about Provider Settings in WorldShare Collection Manager Fundamentals.

 Note: If you are a WMS library or using full WorldShare Collection Manager, please see Provider Settings

About linking IDs

Collections from certain providers require identifiers specific to the provider in order for links to resolve to full-text. The ID is often included in the URL you use to access the provider's platform. For example, if you have an ID "XXX" from a provider:

  • You might access the provider's platform with the URL:
  • In Collection Manager Fundamentals, "XXX" would be the ID needed for Provider ID / Customer ID settings and once entered, the ID would be:
    • Automatically included in MARC records if outputting records from Collection Manager Fundamentals. For example: =856 40$u$zClick for resource
    • Referenced in corresponding links in your discovery interface. For example:

Configure provider settings

  1. First, see the table below to see if you have a collection from a provider that requires a linking ID. If your provider is listed, continue with the steps below. If you do not know your ID, contact your provider before you proceed:
  2. Navigate to Institution Settings > Provider Settings.
  3. Select your provider from the drop-down list.
  4. Enter the identifier from your provider.

 Note: In special situations, you might need to override a linking ID for a particular collection. For help, see Collection-level settings in knowledge base collections, Use Proxy.

Make sure the correct collection is selected

  1. Search in Collection Manager Fundamentals. See Tips for using the search field.
  2. Verify that the correct collection and title is selected in the knowledge base.

Verify the format and coverage

Verify that the title-level format is one that will surface links:

  • Journal, Full Text (The following values will not surface links: Print, Selected Full Text, Abstracts, and Indexed. Only Full Text titles will surface links.)
  • e-Book
  • Audio
  • Image
  • Video

Verify that your coverage information is represented correctly. Coverage can include:

  • Dates, Enumerations, or both

See KBART values and formatting for information on how to represent coverage information.

Check title metadata

OCLC number

Verify that there is an OCLC number and that it is correct. Verify that the OCLC number in the knowledge base matches that in the WorldCat record.

Standard Number

Verify that there is an ISSN/ISBN and that it is correct. Verify that the number in the knowledge base matches that in the WorldCat record.

If the Standard Number is incorrect, report it to OCLC Support.
