{{ ISBN?}}

{{ 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=April 2024}} or {{ISBN?|date=April 2024}}

With a reference formatted via a Citation Style 1 template ({{ Cite web}}, {{ Cite book}}, {{ Citation}}, etc.):

Place {{ISBN missing|date=April 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.

With a free-form reference, just append {{ISBN missing|date=April 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= (you must use HTML  comment tags to hide the message from the citation processing software)

2. Place

{{
No ISBN}}

outside the citation template

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!
