Use this template to create a link to Special:BookSources for an International Standard Book Number without the usual "ISBN" prefix. For example, in a table with a column labelled "ISBN", it would be redundant to write "ISBN" before every International Standard Book Number in the column.
An ISBN link is created by using the {{ISBN}} template with the International Standard Book Number. Example:
{{ISBN|978-1-4133-0454-1}} produces ISBN 978-1-4133-0454-1In tables (or other applications) where the letters "ISBN" would be redundant, this ISBNT template may be used instead, and the link still gets created automatically:
{{ISBNT|1-4133-0454-0}} produces 1-4133-0454-0{{ISBNT|978-1-4133-0454-1}} produces 978-1-4133-0454-1{{ISBNT|978-1-4133-0454-1|978-1-4133-0454-1|978-1-4133-0454-1}} produces 978-1-4133-0454-1, 978-1-4133-0454-1, 978-1-4133-0454-1{{ISBNT|978-1-4133-0454-1|978-1-4133-0454-1|978-1-4133-0454-1|leadout=and}} produces 978-1-4133-0454-1, 978-1-4133-0454-1 and 978-1-4133-0454-1This template uses Module:Check isxn to validate the ISBN. If the ISBN is not valid, this subtemplate will still generate the link, and it will add the article to Category:Pages with ISBN errors.
Since invalid ISBNs are sometimes used in publications, it is possible to disable the validity check for individual ISBNs 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.
