The scope of heritage evolves in time and space. It depends on experts on the one side, and on the relationship that societies maintain with their past on the other. The intentional destruction of monuments shows how they carry cultural identities and economic values. The economics of the built cultural heritage raises questions linked to value, prices and regulations. The value of real estate changes with labels. Digitisation transforms the conditions of access, while globalization (from mass tourism to United Nations Educational, Scientific and Cultural Organization lists) designs a collective concern for the future of historical monuments.
E-books are complements to and not substitutes for paper books, but the development of a market for e-books can disrupt the publishing industry by changing the value chain and challenging regulations. The future of e-books depends on the ability of traditional publishers and newcomers to implement new business models with prices consistent with the willingness-to-pay of e-consumers.
