Use this template as a warning that some or all books cited in the article do not have their ISBNs specified.

To add this template to an article, simply copy and paste {{Lacking ISBN|date=जुलाई 2020}}.

Articles that contain the {{Lacking ISBN}} template are included in Category:Articles lacking ISBNs


  • WP:CITE states that an ISBN is optional in the citation of a book. Therefore, do not restore this template over objections.
  • Do not use this template to warn about books that were not assigned an ISBN by their publishers. Most books originally published before 1974 do not an ISBN, though later editions of such books should have an ISBN.

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

Add an ISBN to every possible book cited in the article. See Wikipedia:ISBN


  • An ISBN directs the reader to one edition of a book. If an ISBN is added to a citation at a later date, its edition may differ from the edition originally used as the source in the article. Therefore, a risk arises that its page numbers or even its content may not match the citation. When in doubt, check with the main author(s) of the article or discuss on the article's talk page. As with all CITEVAR issues, defer to the citation system used by the first major contributor if no consensus can be reached.
