Manual:ISBN

MediaWiki 1.28.0 and later
According to RFC "Future of magic links" ISBNs will no longer be linking automatically to Special:BookSources by default. Templates like should be used instead to create the respective links. To restore the automatic linking use configuration parameter.

MediaWiki 1.20.0 to 1.27.x
To customize Special:BookSources, edit the page "Book_sources" (not done on this very wiki) in the project namespace as defined with configuration parameter, e.g. "Project:Book sources" or the equivalent page name as defined by system message MediaWiki:Booksources.

In the wikitext of page "Project:Book sources", use the  variable wherever you want the ISBN to be included. For instance, to link to an Amazon.com search by ISBN, enter this wikitext:

For an example, see Wikipedia:Book sources.

MediaWiki 1.16.0 to 1.19.x
Mediawiki recognizes inline ISBNs; for example: the wikitext becomes ISBN 0-12-345678-9 (the dashes are optional), which corresponds to Special:Booksources/0123456789. This is a link to a special booksource page, generated on-the-fly by the script. You can influence the appearance of that generated page by putting your custom text into the pages Sadly, however, this only changes the text on the page, but not the list of shops. That shop list currently comes hard-coded from the file , where  is the current language of your Wiki. For example, the default Mediawiki installation in  assigns: And there sadly is no possibility to override this in. It would already be better if the above assignment would be done only if  has not already assigned a value. The only 2 ways to currently change that list are: Both changes sadly will be overwritten with your next MediaWiki software upgrade. For Germany, this could for example be changed to etc.
 * 1) You patch that file directly with your custom shop list.
 * 2) You patch that file a little to only assign that value when   has not done so already.
