I don't recall where I first read about this olfactory revolution for ebook readers, but it's an amusing bit of trivia.
From Wired blog:
"The folks at Smell of Books, though, think they have the answer: a spray-can loaded with, that’s right, the smell of books. A quick spritz from the aerosol can and your Kindle, Sony Reader or iPhone will be transformed into a romantic bundle of musty smelling stories."
Smell of Books
The Guardian jumps in with their own innovation. Perhaps books themselves could be sprayed ?
"What might a JK Rowling smell like? Unwashed teenage boy, perhaps, with a whiff of owl droppings."
