This category holds articles that use any of the short-cite templates ({{harv}} and {{sfn}} template families, and {{harvc}}) where one or more of those short-cite templates do not properly link to a full citation, the target. See guidance at Category:Harv and Sfn template errors to resolve.

Currently, two user scripts relatively reliably detect errors

• User:Svick/HarvErrors.js – Errors only
• User:Trappist the monk/HarvErrors.js – Errors + Warnings about potential errors when short footnote templates are used. This has substantially fewer pointless warnings than Ucucha's old script.

as well as a third experimental method based on customizing a .css page. The three methods are

Method 1 – Automatic script installation

Go in the 'Gadgets' tab of your preferences and select the 'Install scripts without having to edit JavaScript files' option at the bottom of the 'Advanced' section.

Click on the 'Install' button in at the top of either User:Svick/HarvErrors.js, or User:Trappist the monk/HarvErrors.js

Method 2 – Manual script installation

Go to Special:MyPage/common.js and add any of

importScript('User:Svick/HarvErrors.js'); // Backlink: [[User:Svick/HarvErrors.js]]

importScript('User:Trappist the monk/HarvErrors.js'); // Backlink: [[User:Trappist the monk/HarvErrors.js]]

in your skin page, like this. Alternatively, you can go to Special:MyPage/skin.js to make the script apply only to your current skin.

Method 3 – .css code for error messages emitted by the short-cite templates

Error messages are emitted by the various short-cite templates via Module:Footnotes and Module:Harvc. Because of technical limitations, the modules can emit false-positive error messages along with valid error messages. For this reason, no-target error messages are hidden by default. To show these hidden error messages, include the following text in your common.css page or your specific skin.css page:

.harv-error {display: inline !important;} /* display Module:Footnotes errors */

Error message display may be enabled in the future.
