The WorldCat Discovery DEI Initiative aims to reduce harm in item description. Given the global nature of WorldCat Discovery, we acknowledge that there is no one-size-fits-all solution for item description. The first phase of this new functionality provides libraries with the ability to locally re-map subject headings to display locally preferred subjects and facilitate a more inclusive experience for library users in their local community. The second phase will allow libraries to build on their work and define local search expansions to ensure the most relevant results are returned for users.
Local subject re-mapping
Create a spreadsheet to define local re-mapping for subject headings using a universal template provided by WorldCat Discovery. Use the template to replace the existing local subject heading with an updated locally defined subject heading. Upload this template to the OCLC Service Configuration to surface the local inclusive subject heading in your library's WorldCat Discovery interface.
Note: Uploading this file does not modify local bibliographic data or the WorldCat record itself; it changes the way subjects display in the user interface for your institution only. With the first phase of this project, the inclusive subject will display on the first term it matches on. An additional release will expand the functionality to allow replacement on all relevant subject matches.

Download and edit the Local subject re-mapping template
After accessing the template:
- Adding to the universal template allows for it to be a collaborative document where libraries can benefit from the re-mapping solutions being defined globally. Add your local subject re-mappings to the universal template, being careful not to delete any previous work.
- Download the template.
- Navigate to File > Download > Tab Separated Values (.tsv). The template is exported to your system as a tab-separated values sheet and able to be edited locally.
- Open the file and populate the sheet to meet your subject heading needs. Refer to the Subject mapping column definitions for more information and for required fields.
- Save the modified file as a tab-separated values (.tsv) file.
Subject mapping column definitions
Find the definitions for the subject re-mapping configuration file. An asterisk (*) after the field name denotes a required field that will be checked by the system upon upload into service configuration.
The standard country code as described in Standard country or area codes for statistical use (M49)..
The institution's unique OCLC symbol.
The subject access field for the sensitive subject heading.
|6xx 2nd Indicator||
The thesaurus a subject term originates from.
|6xx 2 value||
The source of the subject heading or term.
The category of the group of terminology that reflects the same value.
The sensitive subject heading to be replaced.
The locally defined, inclusive subject heading your library wishes to display.
Use wildcards to define where subjects are replaced
Leverage wildcards to define rules about where locally preferred, inclusive subjects can display. Where the subject can be replaced is denoted using an asterisk (*).
|Asterisk (*) location||Result|
|Subject Being Replaced*||An inclusive subject can replace a subject for display if it occurs at the beginning of a string.|
|*Subject Being Replaced||An inclusive subject can replace a subject for display if it occurs at the end of a string.|
|*Subject Being Replaced*||An inclusive subject can replace a subject for display in the middle of a string.|
Note: For libraries using Chinese, Japanese, or Korean, a subject heading needs to be encased by two asterisks to allow for sub-string replacements like so: **Subject Being Replaced**
Upload the Local subject re-mapping template to the OCLC Service Configuration
Refer to Alternate Subject Headings.
Caution: The file type must be a tab-separated values (.tsv) file or the upload will not work. The row limit on the spreadsheet is 2,000 rows. We encourage using wildcards, where possible, in order to maximize the number of subject headings that can be changed.
- Navigate to the OCLC Service Configuration.
- From the left navigation, select the WorldCat Discovery and WorldCat Local module.
- Select Search Settings and navigate to the Alternate Subject Headings section.
- Toggle on the Display alternative subject headings in search results and item details setting.
- Select the Browse button to find and select your tab-separated values file for upload.
- Determine whether to configure a custom message for library users. Users will see this language if they click on a locally defined subject replacement, warning them that the original subject will be displayed when the search is run.
