We're talking about a new exhibition at the Bodleian Libraries in Oxford, which celebrates touching, tasting, seeing, smelling and hearing books. It looks at the sensory appeal of reading physical books from flip-books to pop-ups and even a book made from processed cheese slices. They even bottled the smell of books. Our guest is Kate Rudy, Professor of Art History at the University of St Andrews, who is one of the co-curators of this exhibition
