Category:CS1 maint: ASIN uses ISBN

Lua error in package.lua at line 80: module 'strict' not found. Lua error in package.lua at line 80: module 'strict' not found. This is a tracking category for CS1 citations that use |asin= where the assigned value is an ISBN. Module:Citation/CS1 checks the ASIN value and if the value is an ISBN (passes the length, composition, and checksum tests) adds the page to this category. Citations that have |asin=ISBN parameters should be changed to |isbn=ISBN parameters. Associated |asin-tld= parameters should be removed. Pages in this category should only be added by Module:Citation/CS1.

While most of the Citation Style 1 and Citation Style 2 error messages are visible to all readers, some remain hidden. Editors who wish to see all of the CS1|2 error messages can do so by updating their common or skin CSS stylesheet to include:

.citation-comment {display: inline !important;} /* show all 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 WP:NULLEDIT will resolve that issue.

The above code is required if you wish see maintenance category messages:
