A quick thought on "Old Book Smell"

I'm one of those people who gives much credence to the smell of a book. I will burrow my nose right in the creases of a book and take a deep whiff. I've never given much thought to it, but browsing around on the internet I came across this gem:

"old book smell. Did you know? 'Lignin, the stuff that prevents all trees from adopting the weeping habit, is a polymer made up of units that are closely related to vanillin. When made into paper and stored for years, it breaks down and smells good. Which is how divine providence has arranged for secondhand bookstores to smell like good quality vanilla absolute, subliminally stoking a hunger for knowledge in all of us.'"

Now isn't that some food for thought?
