{{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 edit

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

  1. Place {{ISBN missing|date=April 2024}} outside the citation template
  2. red-outlined triangle containing exclamation point 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 edit

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:
  1. Add the ISBN as appropriate to the citation, preferably using the {{ISBN}} template, or...
  2. 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
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!
