The Smell of Old Books - a podcast by Dr Chris Smith

Books can hold stories, knowledge, ideas and memories - but what about the smell? So on this week's QotW - What gives an old book that distinctive smell? Also, we ask how we perceive the 'size' of an odour, and if there's more carbon dioxide in the atmosphere - is it leading to bigger caves? Like this podcast?
