[ISBN missing]

Documentation icon Template documentation[view] [edit] [history] [purge]

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

Usage[edit]

{{ISBN missing|date=April 2014}}

  • With references in a Citation Style 1 template ({{Cite web}}, {{Cite book}}, {{Citation}}, etc.):
    • Place {{ISBN missing}} outside the citation template
    • ⚠ Do not place this template in the |isbn= parameter of a Citation Style 1 citation. The inclusion of text other than an ISBN in |isbn= corrupts the citation's COinS metadata and the citation's link to Special:BookSources.
  • With a free-form reference citation, just append {{ISBN missing}} to the end of the citation.

How to fix the problem flagged by this template[edit]

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, add the ISBN
    1. |ISBN=X-XXXX-XXXX-X
    For a free-form citation
    :
    1. Just add the ISBN as appropriate to the format of the citation; or...
    2. 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.
    1. Explicitly state that the ISBN was unspecified:
      |ISBN=<!-- ISBN unspecified --> (you must use HTML <!-- --> comment tags to hide the message from the citation processing software)
    For free-form citations:
    No ISBN specified.
    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 |ISBN=none, |ISBN=unknown or anything else vague; any implication other than that the source itself did not specify an ISBN is simply a signal to other editors to re-tag it with {{ISBN missing}}.
  • If you don't know:
    1. 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.
