We stand amazed by the vitality of printed books, a more than 500-year-old technique, both on and offline. We have observed over the years all of the dialogue which books have created around themselves, through 150 interviews with readers, bookshops, publishers, bloggers, library assistants, 25 participant observations, 750 responses to an online questionnaire and 5,000 mapped sites in France and the francophone world. An impressive collective activity. So, yes, your book carries on living just by staying on your shelf because you talk about it, remember it, and refer to it in conversation. Even better still, you might have lent it to a friend so that she can read it, perhaps you have spent time with people who have spoken about it before buying it, or after having read it. You will have encountered official reviews, of course, and also blogs about it. The conversation goes on even when the book is no longer in circulation.
