If your EPUB has a print counterpart, it's a good idea to include a Page List in the EPUB. A Page List maps your eBook content to print pages. This helps readers who may be referring to both the print and electronic versions of the content (for example, in a classroom setting, or when looking up a citation).
In an EPUB 2 file, the Page List goes in the NCX file. You can put it right after the closing </navMap> tag, for example. It looks like this:
<pageList> <pageTarget id="page3" type="normal" value="3" playOrder="59"> <navLabel><text>3</text></navLabel> <content src="intro.xhtml#page3"/> </pageTarget> <pageTarget id="page4" type="normal" value="4" playOrder="60"> <navLabel><text>4</text></navLabel> <content src="intro.xhtml#page4"/> </pageTarget> ... </pageList>
An example NCX file including a Page List is included in the OPF spec.
Note: All of the
playorder="" values in your entire NCX file must be in numerical order, from top to bottom. This includes the values of the
playorder="" attributes in the NavMap, PageList,and NavList sections.
In an EPUB 3 file, the Page List goes in the Navigation Document, and it looks like this:
<nav epub:type="page-list" hidden=""> <ol> <li><a href="intro.xhtml#page3">3</a></li> <li><a href="intro.xhtml#page4">4</a></li> <li><a href="chapter1.xhtml#page5">5</a></li> ... </ol> </nav>
The EPUB 3 Accessibility Guidelines provide more information about Page Lists, as well as information about marking up page breaks within an EPUB.
