Paper books smell AWFUL.
Period.
Many veteran bookworms (like myself) would swear that they smell nice. That is simply a
Pavlovian Reflex.
We were conditioned to associate smell of mouldy pulp, slowly decomposing organic glue (**), aggresive chemicals used to process brown pulp into white paper, unwashed hands of dozens of people reading the library book at the loo with all those countles hours of [reading] pleasure we get from those smelly books.
(**) you do NOT want to know what was the
glue manufactured from some 50 years ago
