DAISY—Structure Guidelines: Intro to Structured Markup, Page ID

It is not a requirement that pages be individually tagged in a DTB, but it is strongly recommended for textbooks or books that may be used for study purposes. When tagging the pages of a book, all pages should be included.

To aid in navigation, each page number should be placed preceding the first text on the page, regardless of its location in the printed book. This allows the Go To Page feature of most players to navigate directly to the top of a given page, so that playback begins with the requested page and includes the full content of that page. When a chapter or section begins at the top of a page, the level tag would occur first, followed by the page number, the heading (if present in the printed book), and then the text.

Sentences often span a page break. A standard procedure for placement of the page tag should be developed by producing organizations, and the tagging should be handled consistently in all books produced. Some organizations consider it best practice to place the page tag at the the end of the sentence, rather than mid-sentence. For example, if only the first one or two words appear on the previous page, the page tag would be placed at the beginning of the sentence (on the page prior to the actual page break). Other organizations choose to place the page tag exactly where it appears in the sentence. It would not however be appropriate to place a page tag mid-word if a word is broken and hyphenated at the page break.

Blank pages should be tagged and assigned the appropriate page numbers regardless of whether a printed number appears on the pages of the print book. The listener should also receive aural confirmation of the existence of blank pages.
