Have you ever noticed the following:
You buy a book and usually it smells kinda good, the mix of heavy paper and ink. Sometimes, when you buy a second hand book, you have this smell in a older, heavier way and as long as these books were in good clean hands, it still is a pretty pleasant smell.

But for some reason only literature of the leisure kind has this character. Something is different about study books. somehow they lack this and i wonder why? It is pretty much the same thing, only the content is different, everything else, paper, ink, cover, should be the same or do i miss something?
