It seems to me e-readers don’t fully exploit the affordances digital publishing provides. Specifically when it comes to non-linear reading of non-fiction.
My Nova2 at least allow me to see both the table of contents alongside my current page, as well as my notes. This makes flipping back and forth easier. Kindle doesn’t.
But other things that would be possible are missing. With a paper book you have an immediate sense of both the size of the document and your current point within it. My e-reader can show me I am at 12% or position 123 of 456, but not a visual cue that doesn’t require interpretation.
More importantly my e-readers don’t manipulate a book like they should be able to given it is digital. Why can’t I collapse a document in various ways? E.g. show me the first and last paragraph of each chapter. Now add in all subheadings. Now add in all first and last sentences of a sub header and show all images. Etc. More advanced things would be e.g. highlighting referenced books also in my library and being able to jump between them. Or am I overlooking functionalities in my e-readers?
Also welcome: more publishers that sell a combination of a the physical and digital book.
How do you read non-linearly in e-books? What are your practices?
