Category:CS1 maint: ASIN uses ISBN


This is a tracking category for CS1 citations that use |asin= where the assigned value may be an ISBN. Module:Citation/CS1 checks the ASIN value and if the value has the form of an ISBN (passes the length, composition, and checksum tests) adds the page to this category. While the value assigned to |asin= may appear to be an ISBN, in fact, the value may not be. It appears that |asin=630... values are not ISBNs.

When the value assigned to |asin= parameters is a valid ISBN, |asin=ISBN should be changed to |isbn=ISBN. When there is an existing |isbn= parameter, the |asin= parameter should be removed. Associated |asin-tld= parameters should be removed. Pages in this category should only be added by Module:Citation/CS1.


By default, Citation Style 1 and Citation Style 2 error messages are visible to all readers and maintenance category messages are hidden from all readers.

To display maintenance messages, include the following text in your common CSS page or your specific skin's CSS page (common.css and skin.css respectively):

.mw-parser-output span.cs1-maint {display: inline;} /* display Citation Style 1 maintenance messages */

To display hidden-by-default error messages:

.mw-parser-output span.cs1-hidden-error {display: inline;} /* display hidden Citation Style 1 error messages */

Even with this CSS installed, older pages in Wikipedia's cache may not have been updated to show these error messages even though the page is listed in one of the tracking categories. A null edit will resolve that issue.

To hide normally-displayed error messages:

.mw-parser-output span.cs1-visible-error {display: none;} /* hide Citation Style 1 error messages */

You can personalize the display of these messages (such as changing the color), but you will need to ask someone who knows CSS or at WP:Simple talk if you do not understand how.
