{{H:h}}

For a book with ISBN e.g. 0131103628, the simple wikitext "<nowiki>ISBN 0131103628</nowiki>" gives ISBN 0131103628, with the same target as  [[Special:Booksources/0131103628]]: the text of  [[MediaWiki:Booksources-text]] and links regarding the book according to the contents of the page "Book sources" in the project namespace (ns4, here: ''Meta''), where each occurrence of '''MAGICNUMBER''' is replaced with the ISBN.

If there is no such "Book sources" page, a default page is displayed. It uses the settings ''$wgBookstoreListEn'' in [[Language.php]], currently:

<pre>
/* private */ $wgBookstoreListEn = array(
	"Amazon.com" => "http://astore.amazon.com/amazon-books-20/detail/$1"
	"Amazon.de" => "http://astore.amazon.de/www.amazon.de-21/detail/$1"
        "Amazon.fr" => "http://astore.amazon.fr/www.amazon.fr-21/detail/$1" 
        "Amazon.co.uk" => "http://astore.amazon.co.uk/www-amazon-co-uk-21/detail/$1" 
	"AddALL" => "http://www.addall.com/New/Partner.cgi?query=$1&type=ISBN",
	"PriceSCAN" => "http://www.pricescan.com/books/bookDetail.asp?isbn=$1",
	"Barnes & Noble" => "http://shop.barnesandnoble.com/bookSearch/isbnInquiry.asp?isbn=$1",
);
</pre>

The name of the book sources page can be changed by editing [[MediaWiki:Booksources]]<sup>[dead link]</sup>, but the name space cannot.

== Alternative ==
Use a template like [[Template:ISBN]] allowing <nowiki>{{ISBN|193151447X}}</nowiki> to produce something like:

{{ISBN|193151447X}}

However, often a separate page would be desirable. This can be done, but requires a page like [[193151447X]] for every book. Those pages can call [[Template:Bk]], so that they only have to contain <nowiki>{{bk}}</nowiki>.
