According to The New York Times:
In the spring Hachette Book Group called its version, by David Baldacci, an “enriched” book. Penguin Group released an “amplified” version of a novel by Ken Follett last week. And on Thursday Simon & Schuster will come out with one of its own, an “enhanced” e-book version of “Nixonland” by Rick Perlstein.
In the future we look forward also to having our reading material “augmented,” “supplemented,” “expanded,” “intensified,” “elevated,” “heightened,” “adorned,” “bedecked,” “embellished,” “illuminated,” and “festooned.” Yes!
