the unrelated Istituto Centrale per il Catalogo Unico SBN identifiers ਲਈ, ਦੇਖੋ Template:ICCU।
Usage
Use this template to create a link (or list of links) to Special:BookSources for one or more Standard Book Numbers with "SBN" prefix. The template supports 9-digit SBNs (with or without hyphens). The prefix link deliberately goes through an (identifier) redirect in order to aid reverse lookup of articles which contain SBN links from specific books (rather than only mentioning the concept of Standard Book Numbers in general).
If the leading "SBN" link should not be linked to (for example because it was already linked to in the article), it can be suppressed using the link=no parameter:
This template uses Module:Check isxn to validate the SBN. If the SBN is not valid, this subtemplate will still generate the link, and it will add the article to Category:Pages with ISBN errors.
Since invalid SBNs are sometimes used in publications, it is possible to disable the validity check for individual SBNs given as parameters. In order to do so, add invalid?=yes (with ? replaced by the parameter number 1 to 9) to the template. In this case, the article will be added to Category:Pages with listed invalid ISBNs.
