Current Issues  

Issue Details
Shelf Browse: The shelf browse feature on item detail records intermittently does not display results. Targeted Resolution: TBA
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. Targeted Resolution: TBA
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. Targeted Resolution: March 2023
Date format: Some locales are incorrectly displaying US Date format. Targeted Resolution: TBA
Searches using wildcards: Wildcard and truncated searches are returning inconsistent results. Targeted Resolution: TBA
Peer Reviewed Filter: When this filter is selected, the search results are not displaying all peer-reviewed resources that a library may hold.  Targeted Resolution: TBA
Date (Newest First) sort: For some search results, some older materials are sorted first, above those published more recently.   Targeted Resolution: TBA

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. 
Targeted Resolution: TBA

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.  
Targeted Resolution: March 2023
Full-text embargo: For some articles, held-by statements are not honoring the full-text embargo period Targeted Resolution: TBA
Branch scoping: In some instances, holdings display incorrectly when search is scoped to the branch that holds them  Targeted Resolution: TBA
Incorrect holdings: For some items, incorrect holdings display depending on what index the user searches. This could result in full text, hold, and ILL links showing up when a record is viewed from search results but not when it is viewed via the "Share" link. There are multiple fixes for this issue. Targeted Resolution: TBA

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.

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
