It's good to have the clarification, Bill, because I was using it in both ways simultaneously. Careless of me! You need to maintain a record in the digital file of where the page breaks occur in the paginated version of record. But under certain circumstances, you need to replicate that in the rendered pages. Sighted users also sometimes need to use an online version for accessibility reasons (or by choice, but my concern is always going to be with accessibility). Those users also need to be able to have a visually rendered page as if it were print. There are any other number of reasons, both accessibility and design, why rendering a paged model would be desirable. E-book versions of picture books, for example, need visually rendered pages. There are good reasons to have visual pagination because of user preference, as has been discussed further up this thread, but there are also solid use cases where it is required, which is why I was bringing up accessibility and scholarship. Kaveh, adding pagination to the CSS requirements does not preclude in any way doing the richer kind of pagination you are describing for specific functionality. However, it is vitally important that, for the use cases were pagination is necessary, it is available. Deborah Kaplan prio On Tue, 4 Aug 2015, Bill Kasdorf wrote: > > A quick clarification.
