Template:Book category header/doc
|This is a documentation subpage for Template:Book category header
It contains usage information, categories and other content that is not part of the original template page.
|This template is used on 3,000+ pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.
Use this template on a book category, containing all the pages of a book (rather than, say, a subject category containing all books relating specifically to that subject; or some other kind of category). See Using Wikibooks/Shelves, Categories, and Classifications for details.
The list of subpages link via Special:PrefixIndex puts a slash after the book name, thus excluding the book main page, because the slash also prevents listing pages of other books whose names have the current book's name as a prefix (for example, at this writing, Special:PrefixIndex/Apache).
