ISBN missing is an inline cleanup template flagging a broken source citation that is missing the ISBN of the cited source.

Usage
This template should not be substituted.


 * With references in a Cite-type template (Cite web, Cite book, Citation, etc.):
 * ISBN
 * With a free-form reference citation, just append to the end of the citation.

How to fix the problem flagged by this template
Do not remove the template without fixing the problem one of the following ways.


 * If you know the ISBN, fill in the needed information, and remove the template.
 * For a template-formatted citation, there are three basic ways to do this&#58;:
 * X-XXXX-XXXX-X
 * For a free-form citation&#58;:
 * Just add the ISBN as appropriate to the format of the citation; or...
 * Better yet, convert the entire citation to Cite journal, Cite news or some other Cite-series template, as appropriate for the work in question.


 * If you know that no ISBN was specified by the original source, as is common with older books, you have the following option.
 * Explicitly state that the ISBN was unspecified (it will appear inside parentheses in most citation templates, but if it does not it should probably be put in [square brackets]):
 * ISBN unspecified
 * or
 * [ISBN unspecified]
 * For free-form citations:
 * Do not use question marks.
 * Do not leave the information blank and untag it, or someone else will just come along later and flag this with ISBN missing again!
 * Do not use none, unknown or anything else vague; any implication other than that the source itself did not specify a ISBN is simply a signal to other editors to re-tag it with ISBN missing.
 * Do not use none, unknown or anything else vague; any implication other than that the source itself did not specify a ISBN is simply a signal to other editors to re-tag it with ISBN missing.


 * If you don't know:
 * Check the source, and add the necessary information, as above.
 * Do not use question marks.
 * If the source is a dead link, check archive.org for a backup copy (see your Citation/Cite-type template's documentation for use of archiveurl and archivedate parameters). If no archive copy is available, use Dead link after the citation, but leave ISBN missing as well.
