{{Tl|ISBN missing}} is an inline cleanup template for flagging a reference that is missing the [[International Standard Book Number|International Standard Book Number (ISBN)]] of the source document. The template adds [[:Category:Pages with missing ISBNs]] to the article.

==Usage==
{{tlc|ISBN missing|date&#61;{{CURRENTMONTHNAME}} {{CURRENTYEAR}}}}

*With a reference formatted via a [[Help:Citation Style 1#Templates|Citation Style 1 template]] ({{Tlx|Cite web}}, {{Tlx|Cite book}}, {{Tlx|Citation}}, etc.):
:#Place {{tlc|ISBN missing|date&#61;{{CURRENTMONTHNAME}} {{CURRENTYEAR}}}} outside the citation template
:#{{warnsign|Do not place it in the {{para|isbn}} parameter of a Citation Style 1 template.  The inclusion of text other than the digits of an ISBN in {{para|isbn}} corrupts the citation's [[WP:COinS|COinS]] metadata and the citation's link to [[Special:BookSources]].}}
*With a free-form reference, just append {{tlc|ISBN missing|date&#61;{{CURRENTMONTHNAME}} {{CURRENTYEAR}}}} to the end of the citation.

==How to fix the problem flagged by this template==

'''<span style="color:red">Do not remove the <nowiki>{{ISBN missing}}</nowiki> template without fixing the problem in one of the following ways:</span>'''

*'''Determine the ISBN, add it to the reference, then remove the <nowiki>{{ISBN missing}}</nowiki> template'''
:For a reference formatted via a [[Help:Citation Style 1#Templates|Citation Style 1 template]], use its ISBN parameter:
::{{para|isbn|<var>X-XXXX-XXXX-X</var>}}
:For a free-form reference:
:#Add the ISBN as appropriate to the citation, preferably using the {{tl|ISBN}} template, or...
:#''Better yet'', convert the citation to a [[Help:Citation Style 1#Templates|Citation Style 1 template]].

*'''If you are certain that the source document does not have an ISBN, add a {{tl|No ISBN}} template to the reference, then remove the <nowiki>{{ISBN missing}}</nowiki> template'''
:For a reference formatted via a [[Help:Citation Style 1#Templates|Citation Style 1 template]]:
::1. Use its ISBN parameter to state explicitly that the ISBN does not exist:
:::{{para|isbn|<nowiki><!-- ISBN unspecified --></nowiki>}} (''you must use HTML'' <code><nowiki><!--  --></nowiki></code> ''comment tags to hide the message from the citation processing software'')
::2. Place {{Tlx|No ISBN}} outside the citation template
:For free-form reference, just add {{Tlx|No ISBN}} to the end of the citation.

'''<span style="color:red">If you remove the <nowiki>{{ISBN missing}}</nowiki> template without fixing the problem in one of the above ways, someone else will come along later and flag the reference with <nowiki>{{ISBN missing}}</nowiki> again!</span>'''
