Whenever I read, the start of the journey is always opening the book and breathing deeply. Don’t you find there are few things more wonderful than the smell of a much-loved book? Newly printed books certainly smell very different from older ones. The ink is so crisp. I’ve also noticed that books from different periods & different countries also have very different smells. And then there are the scents of different bindings: leather is marvelous of course but I find a peculiar pleasure in musty worn clothbound books as well. Perhaps just a hint of mildew!
