I was recently reading Matthew Arnold's "Culture and Anarchy" on my K2, and it has physical page numbers corresponding to a specific print edition. They are embedded as [N] in the text; at first I took them for end notes, but once I realized they were page numbers, they became fairly unobtrusive. Here's an example of what I'm talking about
: One screen on the Kindle might show
"This is some text on page 123 of a specific print edition. blah blah blah blah blah. This is the last text on that page [124] and this is the first text on page 124 of the specific print edition. blah blah blah."
Of course, the actual text was a lot more boring than "blah blah blah"!
