You have to remember, also, that the books you see on Alexandria are all a bunch of different events, rendered in order.

So, the Bible will be split down into books, chapters, and verses, and all 30k+ verses will be a different event, so that people can refer to them, or annotate/comment on them, individually.

So, when you're looking at this edition of Jane Eyre, for instance, that is a different for every chapter. It just renders as one document. That can be read online or offline.
