 Knowledge Base Links:

  • In some cases, knowledge base links do not resolve to the correct resource when the start page in the link does not match the start page for the resource
  • In some cases,  knowledge base links do not surface on records in WorldCat Discovery when the title contains diacritics
June 2024
Worldcat Dissertations and Theses database: Searching for records in this database will return zero results. Please search the database and use the Format facet "Thesis, Dissertation" under Book to narrow results. April 2024

Incorrect Holdings:

  • Some articles are not discoverable when search results are clustered
  • Some articles are not discoverable when search results are grouped scoped locally
March 2024
Place Holds: In some cases, when viewing the item details of an article from a journal that your library holds in print, users are not able to successfully place a hold on the volume that contains it. User is presented with the message ‘Ineligible for place hold. No pick up locations available’ February 2024

New result view (Search Alerts Beta Experience): Clustering options should be available in this view, but is not currently functional. 

  • Expected outcome:  All new results will display in the “show all” flat view. Users should be able to cluster the result set as needed.  
  • Workaround: Do not select a different view, other than the “show all” flat view. 
February 2024
Incorrect Holdings: Some records are not discoverable after creation without manual reindexing. A fix was installed to prevent this issue from re-occurring going forward.  OCLC is investigating identifying and re-indexing records previously affected.        January 2024

Incorrect Holdings:

  • Some articles are not discoverable when search results are ungrouped and scoped locally
  • Some WorldCat bibliographic records are not discoverable when search results are ungrouped and scoped locally
December 2023
Shelf Browse: The shelf browse feature on item detail records intermittently does not display results. December 2023

Knowledge base links (brief search results): In some cases for libraries that hold the print and digital version of an item, knowledge base links display on the print version of the item, but not the digital version. This may persist on the item details page.

Workaround: Select "Group editions and formats" on search results or set default grouping for search results to "Group editions and formats". The knowledge base link will display on the representative record.
October 2023

OpenAthens remote access of the WorldShare ILL form: For libraries that use OpenAthens to manage remote access, when a library user requests an item from WorldCat Discovery, the bibliographic fields in the the WorldShare ILL request form are blank.

On 31 July, the WorldCat Discovery request form was retired and replaced with the new WorldShare ILL form. 

If you encounter this issue, contact OCLC Support, which will adjust your configuration so that you can continue to use the WorldCat Discovery form until this issue is resolved.

October 2023

Pagination on Course Reserves: When navigating Course Reserves, selecting the next page of results or the advance arrow does not bring the user to the next page. This is occurring for the "Courses" list as well as "Temporary Items".

  • Workaround for "Courses" list: In this scenario, selecting the advance arrow or the next page of items a second time brings the user to the next page of courses. This workaround does not work for "Temporary Items". 
October 2023

Search link to original query in new results email (Search Alerts Beta Experience): if a user clicks the link to the original search in an alert email, their original clustering selection is not honored when they navigate beyond the first page of results​

  • Expected Outcome: Clustering options should be retained in this view.​
  • Workaround: Recreate the search in WorldCat Discovery.
August 2023
Peer Reviewed Filter: When this filter is selected, the search results are not displaying all peer-reviewed resources that a library may hold.  August 2023

Branch Scoping: If an institution has configured an OCLC symbol (such as a repository database) as a branch, then scoping searches to that branch will not return search results. Results from that branch are still returned when scoped to the local institution. 

  • Workarounds: 
    • Remove the branch from configuration and continue to get results from the local institution scope.
    • Configure the OCLC symbol as a group scope to continue to scope to that branch. 
July 2023
Incorrect Holdings: Some embargoed articles are incorrectly displaying as held when search results are scoped locally June 2023
Full-text embargo: For some articles, held-by statements are not honoring the full-text embargo period May 2023

Search alert notification (Search Alerts Beta Experience): If the subject of an email exceeds 250 characters, the user will not receive any notifications when new items match their search query. 

  • Expected outcome: Limit the Subject of an email to 250 characters so that notifications will be delivered accordingly. Search alert emails contain the following information so we will need to look at adjusting character limits to accommodate:  <number of new items> new items for '<alert name>' from <institution name> 
  • Workaround: Create search alerts with shorter names.  
March 2023
Broken permalinks: Article permalinks from some databases no longer resolve to content. Many of these links will be fixed, but periodically, OCLC must remove content at the request of publishers/providers which may permanently break a permalink. March 2023
Search Error: For some keyword and title searches, users receive an error message instead of search results. Some of the search terms reported include: fluoxetine, fentanyl, mirtazapine, sertraline, escitalopram, tamoxifen, letrozole, ivermectin, carbasalate, the consultant’s toolkit, peaches, paroxetine, Missouri River Basin Studies. March 2023
Saving changes in service configuration February 2023

Potential data loss (Search Alerts Beta Experience): If a user has received a new result email, THEN turns the alert off in My Account AND turns it back on, the “see all new items” button will no longer resolve correctly. User will receive a message that indicates “This link is no longer valid”. 

February 2023
New result view (Search Alerts Beta Experience): Some functionality will be disabled in this view to indicate to the user that they are viewing a list of new items vs typical discovery experience. Since this list of new items is not a user generated search query, the following features will not have any impact in this view: Save Search, Create Alert, Retain Filters, Sort, and Expand this Search. February 2023
Branch scoping: In some instances, holdings display incorrectly when search is scoped to the branch that holds them  October 2022
Locale-based date display October 2022

Multiple e-links

October 27, 2021

When WMS institutions have configured the "Display hold notes field on Specific Copy/Volume requests to not display on place holds" in the service configuration Place Hold/Request Item module, WorldCat Discovery does not honor the setting. December 16, 2020
When using a search box generated by the service configuration and no results are found, some users cannot successfully select the hyperlink in the informational search bar titled "Do you want to scope up to libraries worldwide"  Workaround: There are two workarounds. If no change to the search box is desired, users can select libraries Worldwide from the facets and filters on the right side of the screen. Alternately, users can adjust the default scope of the search box to be Libraries Worldwide
Branch holding display does not appear when search results are ungrouped

Workaround: Enable grouped display of results when searching branches.

When the filter for the grouped display of results is disabled and only a branch is selected, the “held by” statement displays information for Level 1 Library instead of the selected branch.

"Held by" statement for titles under embargo

Update: As of 12/17/19 we have resolved this issue for most types of Discovery index searches. We are continuing to work on resolving this issue for the no: index search.

In WorldCat Discovery, when an article displays a knowledge base link that has an embargo period or moving wall of coverage, links will correctly display or not display in alliance with the coverage information in your knowledge base title. However, the "Held by" statement uses different logic. It is a known issue that the statement might appear for items not yet available, including those that correctly do not surface links.
Similarly, if a journal title in your knowledge base has multiple coverage ranges with gaps in coverage, articles that surface in Discovery search results that fall within the gap of coverage will have a "Held by" statement. 

Note: For proper link display, your settings must be correct:

In WorldShare Collection Manager, Institution Settings > Coverage > Use Coverage to Determine Holdings should be set to Yes In OCLC Service Configuration, under Default Databases and Licensed Content, Treat as held should be disabled for your selections
