Those of you who are more than casually familiar with books -- those of you who spend your free afternoons in fusty bookshops, who offer furtive, kindly strokes along the spines of familiar titles -- understand that page riffling is an essential element in the process of introducing oneself to a new book. It isn't about reading the words; it's about reading the smell, which wafts from the pages in a cloud of dust and wood pulp. It might smell expensive and well bound, or it might smell of tissue-thin paper and blurred two-colour prints, or of fifty years unread in the home of a tobacco-smoking old man. Books can smell of cheap thrills or painstaking scholarship, or literary weight or unsolved mysteries.
