[dm-l] TAN: How does one reference a location in an electronic book on Kindle or iPad?

Hi all,

Good question from a student: if she is referencing a specific passage in a book on a Kindle that (apparently) has no pages or paragraph numbers, what does she do? She says Kindle has something called "locations" but it isn't clear to me if these are canonical or more like arbitrary bookmarks from how she is describing them (I don't have any ereaders, and so don't know).

Anybody know what you are supposed to do? I guess she could count paragraphs if it was that important, or, as with a very long webpage, just skip providing a location more precise than the entire work on the theory that you could full-text-search for it.
