((ISBN missing)) is an inline cleanup template for flagging a reference that is missing the International Standard Book Number (ISBN) of the source document. The template adds Category:Pages with missing ISBNs to the article.
Usage
((ISBN missing|date=February 2024)) or ((ISBN?|date=February 2024))
- With a reference formatted via a Citation Style 1 template (
((Cite web)),((Cite book)),((Citation)), etc.):
- Place
((ISBN missing|date=February 2024))outside the citation template 
Do not place it in the |isbn=parameter of a Citation Style 1 template. The inclusion of text other than the digits of an ISBN in|isbn=corrupts the citation's COinS metadata and the citation's link to Special:BookSources.
- Place
- With a free-form reference, just append
((ISBN missing|date=February 2024))to the end of the citation. - With either method or format, it will render a [ISBN missing] inline note.
How to fix the problem flagged by this template
Do not remove the ((ISBN missing)) template without fixing the problem in one of the following ways:
- Determine the ISBN, add it to the reference, then remove the ((ISBN missing)) template
- For a reference formatted via a Citation Style 1 template, use its ISBN parameter:
|isbn=X-XXXX-XXXX-X
- For a free-form reference:
- Add the ISBN as appropriate to the citation, preferably using the ((ISBN)) template, or...
- Better yet, convert the citation to a Citation Style 1 template.
- If you are certain that the source document does not have an ISBN, add a ((No ISBN)) template to the reference, then remove the ((ISBN missing)) template
- For a reference formatted via a Citation Style 1 template:
- 1. Use its ISBN parameter to state explicitly that the ISBN does not exist:
|isbn=<!-- ISBN unspecified -->(you must use HTML<!-- -->comment tags to hide the message from the citation processing software)
- 2. Place
((No ISBN))outside the citation template
- 1. Use its ISBN parameter to state explicitly that the ISBN does not exist:
- For free-form reference, just add
((No ISBN))to the end of the citation.
If you remove the ((ISBN missing)) template without fixing the problem in one of the above ways, someone else will come along later and flag the reference with ((ISBN missing)) again!
