WorldCat Discovery release notes, April 2019

Release Date: April 17, 2019


WorldCat Discovery April release highlights

The WorldCat Discovery April release brings the Open Access filter to the freely available website, continuing OCLC’s commitment to improving access to open content in our services.  

Along with the inclusion of the Open Access filter in other OCLC services, this release will also include informative messaging when a user attempts to execute an undefined search, provide improved author filtering when viewing brief search results in addition to correcting a few important issues.

Include Request ID with problem reports

When reporting an issue with WorldCat Discovery, it is extremely helpful to include the Request ID. The Request ID is found at the bottom of the screen on which the issue occurred. Including this information allows us to directly trace what happened on the request we are troubleshooting.

New features and enhancements

Open Access filter in and WorldCat Local

The same open access content filter available in WorldCat Discovery will now be available for any user searching the website or the database in WorldCat Local. The open access content filter narrows a user's search to a subset of databases known for providing open access content.  The open access subset of databases from will continue to grow beyond those currently available:

  • BioMed Central
  • Directory of Open Access Books
  • Directory of Open Access Journals
  • HBO Kennisbank
  • Hindawi eJournals
  • JSTOR Open Access Books
  • JSTOR Open Access Journal Collection
  • KnowledgeUnlatched
  • OAIster
  • Open Editions
  • Open Access Publishing in European Networks
  • Opened Hypotheses
  • Opened Books
  • Paperity
  • PLOS
  • Project Euclid
  • SciELO Journals
  • WorldCat records with a 506 subfield a of “Unrestricted Access Online”

There is no configuration necessary to surface this filter. The content filter will appear as a selectable choice when searching the website or the database in WorldCat Local.

Informative display when an undefined search is attempted

When a user attempts to execute a search from the Advanced Search screen without entering any text, WorldCat Discovery will now display a warning message that provides context about how to correct their workflow in order to retrieve results. Prior to this release there was no indication on the advanced search page to indicate to a user why a search failed when no search parameter was entered.


Improved filtering for author names on brief results

When a user narrows her/his by selecting an author name from the filters and facets listed on the left side of the brief search results screen, the name of the author will now be enclosed with quotations to ensure the author name is treated as an author phrase rather than an author keyword. This update ensures that users will see more precise results when author filtering is in use.

For example, selecting Garcia Marquez, Gabriel from the Author section of facets and filters will now narrow search results to only display the exact match of the author name increasing the precision of the author facet.


Bug fixes

Hosted CONTENTdm thumbnail images using http will now display as cover art

URLs for thumbnail images from hosted CONTENTdm sites that have been synced through Digital Connection Gateway using HTTP protocol in the 856 subfield u of the MARC record will now display in WorldCat Discovery. If these images have been saved with IIIF enabled in the CONTENTdm repository, users will also be able to interact with the IIIF viewer. This correction applies only to thumbnail images in MARC records that meet the following criteria:

  • Synced through Digital Collection Gateway 
  • HTTP URLs that point to Hosted CONTENTdm repositories

Thumbnail images from non-hosted CONTENTdm or non-CONTENTdm repositories that use http (unsecured HyperText Transfer Protocol)  will be unable to be displayed in WorldCat Discovery as cover art images.

Author relator terms in the 1xx and 7xx fields now translate in WorldCat Discovery

In WorldCat Discovery the author relator metadata will now translate in the WorldCat Discovery interface. Prior to this release, relator metadata displayed in only English. This fix applies to the following MARC subfields/fields.

  • Subfield d and subfield e of the following MARC fields:
    • 100
    • 110
    • 700
    • 710
  • Subfield j and subfield 4 of the following MARC fields:
    • 111
    • 711

Translation of the relator terms are supported in the following languages in the April 2019 release with the remaining WorldCat Discovery languages planned for May of 2019.

  • German
  • Dutch
  • French
  • Portuguese
