Template:Please check ISMN
 | This template should not be used in citation templates such as Citation Style 1 and Citation Style 2, because it includes markup that will pollute the COinS metadata they produce; see Wikipedia:COinS. |
 | This template may have no transclusions, because it is substituted by a tool or script, it is used as part of a short-term or less active Wikipedia process, or for some other reason. |
Usage
This template is used to mark an International Standard Music Number (ISMN) that may not be valid. For example:
<syntaxhighlight lang="wikitext"> ISMN 1234-56789 Parameter error in {{ISMN}}: Invalid ISMN. </syntaxhighlight>
The template does not produce any visible change to the article (unless the article is viewed in preview mode):
ISMN 1234-56789 Parameter error in {{ISMN}}: Invalid ISMN.
Rather, it adds the article to the hidden maintenance/tracking category: Category:Articles with invalid ISMNs.
In preview mode, it shows the warning message (Warning: Check ISMN). This warning is shown only in preview mode.
Parameters
The optional parameter |reason= simply provides a comment to explain why the ISSN may not be valid. For example:
<syntaxhighlight lang="wikitext"> ISMN 1234-56789 Parameter error in {{ISMN}}: Invalid ISMN. </syntaxhighlight>
