Overall, there’s a lot of work before a book like this goes native on the web. Better still, it the experience is standardized across vendors—which I have attempted as far as possible with the available tech. I mean scrolling is skeuomorphism off of the physical scrolls too, but that’s the point of start for a root problem here. Native books have never happened on the web, and that’s one main reason why people continue to buy the dead-tree; the lack of availability, bad experience and all.
> Physical reference books are often accessed in a non-linear fashion, and often not alone. But let's forget that second part and focus on non-linear.
The demo does implement random access via page numbers on the tail of the url. This affords both random access i.e non-linear reading and referential accessibility [1].
