Jump to navigation Jump to search

This category is populated by pages and templates that use {{ISBN}} and {{ISBNT}}.

In these templates, ISBN parameters are checked for invalid ISBNs as well as extraneous text such as "ISBN", "N/A", "none", dashes (use hyphens instead), lower-case "x" (use "X" instead), and tab characters.

Error messages for erroneous ISBNs look like one of:

  • Check |isbn= value
  • Invalid ISBN
  • Parameter error in {{isbn}}: Invalid ISBN
