New features and enhancements

Public Notes from Local Holdings Records will display alongside item information in WorldCat Discovery

As a direct result of user feedback we are improving the display of public notes from local holding records 852 subfield z fields to more efficiently communicate information about individual item holdings to users. This will help your users understand which individual item they may or may not want to request. In addition to helping individuals within an institution, this information will also be visible to users of group catalogs. In non-group catalogs the summary of all item notes will continue to display


Example of public note display in Group catalogs after Check Holdings button has been selected.



Prior to this release, public notes would only display in the holdings summary portion of availability displays in WorldCat Discovery suggesting that  the note applied to all of the items in a library collection. 

StackMap can now be displayed based on item availability

If your institution uses StackMap with WorldCat Discovery, you can now configure your site to display the StackMap button only for items that are physically available. This will help your users more easily locate the items they need in your physical collections. to better control the appearance of StackMap links and help your users find items that are physically available. To enable this setting, navigate to OCLC Service Configuration > Third-Party integrations > StackMap > Display StackMap link > Based on Availability.


When you select the option to display the StackMap link “Based On Availability,” the StackMap button will display for items configured with the status available or library use only – available in OCLC Service Configuration > WorldCat Discovery and WorldCat Local > OPAC Statuses, Locations, and Circulation Policies of OCLC Service Configuration  in the accordion Item Availability from OPAC status grid. When an item has the status treatment of Available or Library use only – Available, the StackMap link will display in WorldCat Discovery.


Bug fixes

OpenURL ILL forms fixes

When OpenURL forms are used for placing an ILL request, publisher information will now display correctly. Prior to this release, publisher information that was present in the MARC record 264 field was not transmitted correctly into OpenURL ILL forms like those used with Tipasa and ILLiad.  

The journal title element (jtitle) when present on a chapter citation will now pass correctly into the OpenURL resolver for article/chapter requests. Prior to this release, the jtitle would remain blank on the OpenURL ILL forms for chapter requests. 

Links from the knowledge base will display correctly when they contain the same coverage range

Knowledge base links that have the same coverage ranges but different URLs will be correctly de-duplicated in the WorldCat Discovery interface.
