2. The <bookmap> element

A <bookmap> Opens in new window element is just a more elaborate form of <map> Opens in new window. We recommend using a <bookmap> for anything more complex than an article.

Tip
You don't need to create a <map> for the screen media and a <bookmap> for the print media. If you follow the “one topic per XML file” rule, a single topic map (<map> or <bookmap> depending on the complexity of the contents) is all you need.
What follows is a possible <bookmap> for this tutorial (contents of file tutorial-book.ditamap Opens in new window):
