Amazon adds ‘Real Page Numbers’ to Kindle eBooks:

We wanted to be able to display real page numbers that have value and are useful for those who need to cite a specific passage in a book for class, follow along with their friend in a book club, or simply point a friend to a favorite part of the book.

They’ve also found a way to distribute this new metadata to all previously purchased eBooks, so it matches up to the page numbers from a real book. I wonder how book editions are handled, though – three versions of the same book would have slightly different page numbers.
