 | This module is rated as ready for general use. It has reached a mature form and is thought to be bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
Usage[edit]
Search and display one book pages from its TOC page, in order to create a printable version page, and a navigation bar (automatic "previous" / "next" page buttons).
- See b:Template:printable as a printable page generator.
- b:Template:Nav (or b:Template:footer) as a navigation bar creator.
