The objective of this technique is to ensure that a page-selection mechanism is provided that makes available programmatically all set page locations in the digital publication.
The page-selection mechanism provides a way to locate static page break locations (i.e., where each new page begins) within a digital publication. These locations typically come from a print equivalent of the edition and allow synchronization in, for example, a mix of print and digital publications in environments such as schools and universities.
- +The source of pagination is not limited to print but could match up to any statically paginated alternative, such as a PDF or even a fixed-layout EPUB (i.e., where the content does not reflow to fit the available screen size).
- +The order of the page break locations in a digital publication is not sequential in all cases, and not all page breaks may be represented. Publishers often rearrange and remove content from the paginated source content when creating a digital version.
- -Page lists are a central feature of many digital publishing formats. EPUB 3 defines the page list in its navigation document while EPUB 2 and DAISY 3 use the pageList element in the NCX. The DPUB-ARIA module also includes a doc-pagelist role for identifying the navigation element containing the page list.

Other publications provide a means of page navigation through a 'go to' mechanism.
