New features and enhancements

Expanding your search using authority files

Users can now enable searching across authority files to find relevant search terms, even when using related, variant or deprecated search terms.

Search Expansion

  • A patron’s search term matches on 1xx and 4xx fields of an authority record in order to obtain an authorized term and any related terms to be used in the search query.
  • These authorized and related terms will be added to the original search term to expand the search.

Service Configuration Settings

Configuration for this feature is in> WorldCat Discovery > Search Settings > in the accordion labeled Search Expansion Settings. The accordion is closed by default. When you open the menu, the settings are disabled by default as seen in this screen shot below.


You can configure the following settings

  • Enable or disable the “Expand query using authority data” to show the setting in the Discovery UI
  • Enable or disable the “Expand query using authority data” by default when searching in the Discovery interface
  • Select any or all authority files


When these features are enabled in WorldCat Discovery, the informational bar indicates the expanded terms were used for the search. Users can click the links in the informational bar to see what related terms were used, or they can decide to search again without using expanded terms.

The screen shot below shows the informational bar with these links.


If you click on the “include related terms” link, you will see all the related terms that are now being searched as well as your original search:


Your library staff set the default configuration for this new feature. During any session a user can change the settings by switching the “Expand search with related terms” toggle shown in this screen display.


New labels added for customized filters in the dropdown menus

Based on feedback from our community members we have added new options for customized filters.The following new labels are now available under Search Settings > Search Filters Settings in all supported languages:

Filter Type: Filter Label:
Library Owned by Library
Format Item Format
Topic Subject Headings
Database Results Source
Source Collection

Updated citation style for APA

As part of ongoing updates to citation styles available to our WorldCat Discovery users, the APA 7th edition is now  available in WorldCat Discovery citation options. Prior to this release WorldCat Discovery offered APA 6th edition.

Bug fixes

Corrected issue with scoping down to Level 1 holdings when using Metasearch Content module “Treat as Held”

When you have enabled a database in>Metasearch Content>Default Databases and Licensed Content module and are treating the entire database as held by your institution by enabling the toggle to “Treat as Held” you will now see functionality working for all scoping levels when searching in the WorldCat Discovery interface.



When your users are viewing search results scoped down to their institution in WorldCat Discovery search results, all records from databases set to “Treat as Held” will return correctly.




Prior to this release, users did not see all results from these databases when scoped to their library holdings and needed to adjust their scoping level to Libraries Worldwide to see all results from databases set to “Treat as Held.”


Translation of all seasons in Journal availability status display corrected 

When viewing the WorldCat Discovery interface in their preferred language, users will now see the season, if included in the Journal availability status display, translated correctly. Prior to this release, the season defaulted to English even when it was not the preferred language display.


New content

This is a list of new databases added to WorldCat Discovery, WorldCat Local and since our last update.

You can enable these databases as search options in the Licensed Content and Databases module of the OCLC Service Configuration site. Please remember that your library must have a valid subscription to these databases in order to enable them.
